Member Function Documentation

virtual void Ogre::ResourceManager::_notifyResourceLoaded ( Resource res)
virtualinherited

Notify this manager that a resource which it manages has been loaded.

virtual void Ogre::ResourceManager::_notifyResourceTouched ( Resource res)
virtualinherited

Notify this manager that a resource which it manages has been 'touched', i.e.

used.

virtual void Ogre::ResourceManager::_notifyResourceUnloaded ( Resource res)
virtualinherited

Notify this manager that a resource which it manages has been unloaded.

virtual void Ogre::ResourceManager::addImpl ( ResourcePtr res)
protectedvirtualinherited

Add a newly created resource to the manager (note weak reference)

virtual void Ogre::GpuProgramManager::addMicrocodeToCache ( const String name,
const Microcode microcode 
)
virtualinherited

Adds a microcode for a program to the microcode cache.

Parameters
nameThe name of the program.
static String Ogre::GpuProgramManager::addRenderSystemToName ( const String name)
staticprotectedinherited
bool Ogre::GpuProgramManager::canGetCompiledShaderBuffer ( )
inherited
virtual void Ogre::ResourceManager::checkUsage ( void  )
protectedvirtualinherited

Checks memory usage and pages out if required.

This is automatically done after a new resource is loaded.

virtual ResourcePtr Ogre::GpuProgramManager::create ( const String name,
const String group,
GpuProgramType  gptype,
const String syntaxCode,
bool  isManual = false,
ManualResourceLoader loader = 0 
)
virtualinherited

General create method, using specific create parameters instead of name / value pairs.

Resource* Ogre::GLGpuProgramManager::createImpl ( const String name,
ResourceHandle  handle,
const String group,
bool  isManual,
ManualResourceLoader loader,
const NameValuePairList createParams 
)
protectedvirtual

Create a new resource instance compatible with this manager (no custom parameters are populated at this point).

Remarks
Subclasses must override this method and create a subclass of Resource.
Parameters
nameThe unique name of the resource
groupThe name of the resource group to attach this new resource to
isManualIs this resource manually loaded? If so, you should really populate the loader parameter in order that the load process can call the loader back when loading is required.
loaderPointer to a ManualLoader implementation which will be called when the Resource wishes to load (should be supplied if you set isManual to true). You can in fact leave this parameter null if you wish, but the Resource will never be able to reload if anything ever causes it to unload. Therefore provision of a proper ManualLoader instance is strongly recommended.
createParamsIf any parameters are required to create an instance, they should be supplied here as name / value pairs. These do not need to be set on the instance (handled elsewhere), just used if required to differentiate which concrete class is created.

Implements Ogre::ResourceManager.

Resource* Ogre::GLGpuProgramManager::createImpl ( const String name,
ResourceHandle  handle,
const String group,
bool  isManual,
ManualResourceLoader loader,
GpuProgramType  gptype,
const String syntaxCode 
)
protectedvirtual

Specialised create method with specific parameters.

Implements Ogre::GpuProgramManager.

virtual Microcode Ogre::GpuProgramManager::createMicrocode ( const uint32  size) const
virtualinherited

Creates a microcode to be later added to the cache.

Parameters
sizeThe size of the microcode in bytes
virtual ResourceCreateOrRetrieveResult Ogre::ResourceManager::createOrRetrieve ( const String name,
const String group,
bool  isManual = false,
ManualResourceLoader loader = 0,
const NameValuePairList createParams = 0 
)
virtualinherited

Create a new resource, or retrieve an existing one with the same name if it already exists.

Remarks
This method performs the same task as calling getByName() followed by create() if that returns null. The advantage is that it does it in one call so there are no race conditions if using multiple threads that could cause getByName() to return null, but create() to fail because another thread created a resource in between.
See also
ResourceManager::createResource
ResourceManager::getResourceByName
Returns
A pair, the first element being the pointer, and the second being an indicator specifying whether the resource was newly created.
virtual GpuProgramParametersSharedPtr Ogre::GpuProgramManager::createParameters ( void  )
virtualinherited

Creates a new GpuProgramParameters instance which can be used to bind parameters to your programs.

Remarks
Program parameters can be shared between multiple programs if you wish.
virtual GpuProgramPtr Ogre::GpuProgramManager::createProgram ( const String name,
const String groupName,
const String filename,
GpuProgramType  gptype,
const String syntaxCode 
)
virtualinherited

Create a new, unloaded GpuProgram from a file of assembly.

Remarks
Use this method in preference to the 'load' methods if you wish to define a GpuProgram, but not load it yet; useful for saving memory.
This method creates a new program of the type specified as the second parameter. As with all types of ResourceManager, this class will search for the file in all resource locations it has been configured to look in.
Parameters
nameThe name of the program
groupNameThe name of the resource group
filenameThe file to load
syntaxCodeThe name of the syntax to be used for this program e.g. arbvp1, vs_1_1
gptypeThe type of program to create
virtual GpuProgramPtr Ogre::GpuProgramManager::createProgramFromString ( const String name,
const String groupName,
const String code,
GpuProgramType  gptype,
const String syntaxCode 
)
virtualinherited

Create a GPU program from a string of assembly code.

Remarks
Use this method in preference to the 'load' methods if you wish to define a GpuProgram, but not load it yet; useful for saving memory.
The assembly code must be compatible with this manager - call the getSupportedSyntax method for details of the supported syntaxes
Parameters
nameThe identifying name to give this program, which can be used to retrieve this program later with getByName.
groupNameThe name of the resource group
codeA string of assembly code which will form the program to run
gptypeThe type of program to create.
syntaxCodeThe name of the syntax to be used for this program e.g. arbvp1, vs_1_1
virtual ResourcePtr Ogre::ResourceManager::createResource ( const String name,
const String group,
bool  isManual = false,
ManualResourceLoader loader = 0,
const NameValuePairList createParams = 0 
)
virtualinherited

Creates a new blank resource, but does not immediately load it.

Remarks
Resource managers handle disparate types of resources, so if you want to get at the detailed interface of this resource, you'll have to cast the result to the subclass you know you're creating.
Parameters
nameThe unique name of the resource
groupThe name of the resource group to attach this new resource to
isManualIs this resource manually loaded? If so, you should really populate the loader parameter in order that the load process can call the loader back when loading is required.
loaderPointer to a ManualLoader implementation which will be called when the Resource wishes to load (should be supplied if you set isManual to true). You can in fact leave this parameter null if you wish, but the Resource will never be able to reload if anything ever causes it to unload. Therefore provision of a proper ManualLoader instance is strongly recommended.
createParamsIf any parameters are required to create an instance, they should be supplied here as name / value pairs
virtual GpuSharedParametersPtr Ogre::GpuProgramManager::createSharedParameters ( const String name)
virtualinherited

bool  preferHighLevelPrograms = true 
)
inherited

Get a resource by name.

See also
GpuProgramManager::getResourceByName
virtual Real Ogre::ResourceManager::getLoadingOrder ( void  ) const
inlinevirtualinherited

Gets the relative loading order of resources of this type.

Remarks
There are dependencies between some kinds of resource in terms of loading order, and this value enumerates that. Higher values load later during bulk loading tasks.

Implements Ogre::ScriptLoader.

Definition at line 459 of file OgreResourceManager.h.

virtual size_t Ogre::ResourceManager::getMemoryBudget ( void  ) const
virtualinherited

Get the limit on the amount of memory this resource handler may use.

virtual size_t Ogre::ResourceManager::getMemoryUsage ( void  ) const

Definition at line 183 of file OgreResourceManager.h.

virtual const Microcode& Ogre::GpuProgramManager::getMicrocodeFromCache ( const String name) const
virtualinherited

Returns a microcode for a program from the microcode cache.

Parameters
nameThe name of the program.
ResourceHandle Ogre::ResourceManager::getNextHandle ( void  )
protectedinherited

Allocates the next handle.

ResourcePtr Ogre::GpuProgramManager::getResourceByName ( const String name,
bool  preferHighLevelPrograms = true 
)
inherited

Overrides the standard ResourceManager getResourceByName method.

Parameters
nameThe name of the program to retrieve
preferHighLevelProgramsIf set to true (the default), high level programs will be returned in preference to low-level programs.
virtual ResourcePtr Ogre::ResourceManager::getResourceByName ( const String name,
const String groupName = ResourceGroupManager::AUTODETECT_RESOURCE_GROUP_NAME 
)
virtualinherited

Retrieves a pointer to a resource by name, or null if the resource does not exist.

ResourceMapIterator Ogre::ResourceManager::getResourceIterator ( void  )
inlineinherited

Returns an iterator over all resources in this manager.

Note
Use of this iterator is NOT thread safe!

Definition at line 567 of file OgreResourceManager.h.

ResourcePool* Ogre::ResourceManager::getResourcePool ( const String name)
inherited

Create a resource pool, or reuse one that already exists.

const String& Ogre::ResourceManager::getResourceType ( void  ) const
inlineinherited

Gets a string identifying the type of resource this manager handles.

Definition at line 462 of file OgreResourceManager.h.

bool Ogre::GpuProgramManager::getSaveMicrocodesToCache ( )
inherited

Get if the microcode of a shader should be saved to a cache.

virtual const StringVector& Ogre::ResourceManager::getScriptPatterns ( void  ) const
inlinevirtualinherited

Gets the file patterns which should be used to find scripts for this ResourceManager.

Remarks
Some resource managers can read script files in order to define resources ahead of time. These resources are added to the available list inside the manager, but none are loaded initially. This allows you to load the items that are used on demand, or to load them all as a group if you wish (through ResourceGroupManager).
This method lets you determine the file pattern which will be used to identify scripts intended for this manager.
Returns
A list of file patterns, in the order they should be searched in.

isScriptingSupported, parseScript

Implements Ogre::ScriptLoader.

Definition at line 435 of file OgreResourceManager.h.

virtual GpuSharedParametersPtr Ogre::GpuProgramManager::getSharedParameters ( const String name) const
virtualinherited

Retrieve a set of shared parameters, which can be used across many GpuProgramParameters objects of different structures.

static GpuProgramManager& Ogre::GpuProgramManager::getSingleton ( void  )
staticinherited

Override standard Singleton retrieval.

Remarks
Why do we do this? Well, it's because the Singleton implementation is in a .h file, which means it gets compiled into anybody who includes it. This is needed for the Singleton template to work, but we actually only want it compiled into the implementation of the class based on the Singleton, not all of them. If we don't change this, we get link errors when trying to use the Singleton-based class from an outside dll.
This method just delegates to the template version anyway, but the implementation stays in this single compilation unit, preventing link errors.
static GpuProgramManager* Ogre::GpuProgramManager::getSingletonPtr ( void  )
staticinherited

Override standard Singleton retrieval.

Remarks
Why do we do this? Well, it's because the Singleton implementation is in a .h file, which means it gets compiled into anybody who includes it.

virtual void Ogre::ResourceManager::parseScript ( DataStreamPtr stream,
const String groupName 
)
inlinevirtualinherited

Parse the definition of a set of resources from a script file.

Remarks
Some resource managers can read script files in order to define resources ahead of time. These resources are added to the available list inside the manager, but none are loaded initially. This allows you to load the items that are used on demand, or to load them all as a group if you wish (through ResourceGroupManager).
Parameters
streamWeak reference to a data stream which is the source of the script
groupNameThe name of the resource group that resources which are parsed are to become a member of. If this group is loaded or unloaded, then the resources discovered in this script will be loaded / unloaded with it.

Implements Ogre::ScriptLoader.

Reimplemented in Ogre::MaterialManager, and Ogre::FontManager.

virtual ResourcePtr Ogre::ResourceManager::prepare ( const String name,
const String group,
bool  isManual = false,
ManualResourceLoader loader = 0,
const NameValuePairList loadParams = 0,
bool  backgroundThread = false 
)
virtualinherited

Generic prepare method, used to create a Resource specific to this ResourceManager without using one of the specialised 'prepare' methods (containing per-Resource-type parameters).

Parameters
nameThe name of the Resource
groupThe resource group to which this resource will belong
isManualIs the resource to be manually loaded? If so, you should provide a value for the loader parameter
loaderThe manual loader which is to perform the required actions when this resource is loaded; only applicable when you specify true for the previous parameter
loadParamsOptional pointer to a list of name/value pairs containing loading parameters for this type of resource.
backgroundThreadOptional boolean which lets the load routine know if it is being run on the background resource loading thread
bool Ogre::GLGpuProgramManager::registerProgramFactory ( const String syntaxCode,
CreateGpuProgramCallback  createFn 
)
virtual void Ogre::ResourceManager::reloadAll ( bool  reloadableOnly = true)
virtualinherited

Caused all currently loaded resources to be reloaded.

Remarks
All resources currently being held in this manager which are also marked as currently loaded will be unloaded, then loaded again.
Parameters
reloadableOnlyIf true (the default), only reload the resource that is reloadable. Because some resources isn't reloadable, they will be unloaded but can't loaded again. Thus, you might not want to them unloaded. Or, you might unload all of them, and then populate them manually later.
See also
Resource::isReloadable for resource is reloadable.
virtual void Ogre::ResourceManager::reloadUnreferencedResources ( bool  reloadableOnly = true)
virtualinherited

Caused all currently loaded but not referenced by any other object resources to be reloaded.

Remarks
This method behaves like reloadAll, except that it only reloads resources which are not in use, i.e. not referenced by other objects.
Some referenced resource may exists 'weak' pointer to their sub-components (e.g. Entity held pointer to SubMesh), in this case, unload or reload that resource will cause dangerous pointer access. Use this function instead of reloadAll allows you avoid fail in those situations.
Parameters
reloadableOnlyIf true (the default), only reloads resources which can be subsequently automatically reloaded.
virtual void Ogre::ResourceManager::remove ( ResourcePtr r)
virtualinherited

Remove a single resource.

Remarks
Removes a single resource, meaning it will be removed from the list of valid resources in this manager, also causing it to be unloaded.
Note
The word 'Destroy' is not used here, since if any other pointers are referring to this resource, it will persist until they have finished with it; however to all intents and purposes it no longer exists and will likely get destroyed imminently.
If you do have shared pointers to resources hanging around after the ResourceManager is destroyed, you may get problems on destruction of these resources if they were relying on the manager (especially if it is a plugin). If you find you get problems on shutdown in the destruction of resources, try making sure you release all your shared pointers before you shutdown OGRE.
virtual void Ogre::ResourceManager::remove ( const String name)
virtualinherited

Remove a single resource by name.

Remarks
Removes a single resource, meaning it will be removed from the list of valid resources in this manager, also causing it to be unloaded.
Note

virtual void Ogre::ResourceManager::remove ( ResourceHandle  handle)
virtualinherited

Remove a single resource by handle.

Remarks
Removes a single resource, meaning it will be removed from the list of valid resources in this manager, also causing it to be unloaded.
Note
The word 'Destroy' is not used here, since if any other pointers are referring to this resource, it will persist until they have finished with it; however to all intents and purposes it no longer exists and will likely get destroyed imminently.

virtual void Ogre::ResourceManager::removeAll ( void  )
virtualinherited

Removes all resources.

Note

virtual void Ogre::ResourceManager::removeImpl ( ResourcePtr res)
protectedvirtualinherited

Remove a resource from this manager; remove it from the lists.

virtual void Ogre::GpuProgramManager::removeMicrocodeFromCache ( const String name)
virtualinherited

Removes a microcode for a program from the microcode cache.

Parameters
nameThe name of the program.
virtual void Ogre::ResourceManager::removeUnreferencedResources ( bool  reloadableOnly = true)
virtualinherited

Remove all resources which are not referenced by any other object.

Remarks
This method behaves like removeAll, except that it only removes resources which are not in use, ie not referenced by other objects. This allows you to free up some memory selectively whilst still keeping the group around (and the resources present, just not using much memory).
Some referenced resource may exists 'weak' pointer to their sub-components (e.g. Entity held pointer to SubMesh), in this case, remove or reload that resource will cause dangerous pointer access. Use this function instead of removeAll allows you avoid fail in those situations.
Parameters
reloadableOnlyIf true (the default), only removes resources which can be subsequently automatically reloaded.
virtual bool Ogre::ResourceManager::resourceExists ( const String name)
inlinevirtualinherited

Returns whether the named resource exists in this manager.

Definition at line 355 of file OgreResourceManager.h.

virtual bool Ogre::ResourceManager::resourceExists ( ResourceHandle  handle)
inlinevirtualinherited

Returns whether a resource with the given handle exists in this manager.

Definition at line 360 of file OgreResourceManager.h.

virtual void Ogre::GpuProgramManager::saveMicrocodeCache ( DataStreamPtr  stream) const
virtualinherited

Saves the microcode cache to disk.

Parameters
streamThe destination stream
virtual void Ogre::ResourceManager::setMemoryBudget ( size_t  bytes)
virtualinherited

Set a limit on the amount of memory this resource handler may use.

Remarks
If, when asked to load a new resource, the manager believes it will exceed this memory budget, it will temporarily unload a resource to make room for the new one. This unloading is not permanent and the Resource is not destroyed; it simply needs to be reloaded when next used.
void Ogre::GpuProgramManager::setSaveMicrocodesToCache ( const bool  val)
inherited

Set if the microcode of a shader should be saved to a cache.

virtual void Ogre::ResourceManager::setVerbose ( bool  v)
inlinevirtualinherited

Sets whether this manager and its resources habitually produce log output.

Definition at line 465 of file OgreResourceManager.h.

virtual void Ogre::ResourceManager::unload ( const String name)
virtualinherited

Unloads a single resource by name.

Remarks
Unloaded resources are not removed, they simply free up their memory as much as they can and wait to be reloaded.
See also
ResourceGroupManager for unloading of resource groups.
virtual void Ogre::ResourceManager::unload ( ResourceHandle  handle)
virtualinherited

Unloads a single resource by handle.

Remarks
Unloaded resources are not removed, they simply free up their memory as much as they can and wait to be reloaded.

ResourceGroupManager for unloading of resource groups.
virtual void Ogre::ResourceManager::unloadAll ( bool  reloadableOnly = true)
virtualinherited

Unloads all resources.

Remarks
Unloaded resources are not removed, they simply free up their memory as much as they can and wait to be reloaded.
