Detailed Description

Class defining the common interface which classes can use to present a reflection-style, self-defining parameter set to callers.

Remarks
This class also holds a static map of class name to parameter dictionaries for each subclass to use. See ParamDictionary for details.
In order to use this class, each subclass must call createParamDictionary in their constructors which will create a parameter dictionary for the class if it does not exist yet.

Member Function Documentation

static void Ogre::StringInterface::cleanupDictionary ( )
static

Cleans up the static 'msDictionary' required to reset Ogre, otherwise the containers are left with invalid pointers, which will lead to a crash as soon as one of the ResourceManager implementers (e.g.

MaterialManager) initializes.

virtual void Ogre::StringInterface::copyParametersTo ( StringInterface dest) const
inlinevirtual

Method for copying this object's parameters to another object.

Remarks
This method takes the values of all the object's parameters and tries to set the same values on the destination object. This provides a completely type independent way to copy parameters to other objects. Note that because of the String manipulation involved, this should not be regarded as an efficient process and should be saved for times outside of the rendering loop.
Any unrecognised parameters will be ignored as with setParameter method.
Parameters
destPointer to object to have it's parameters set the same as this object.

bool Ogre::StringInterface::createParamDictionary ( const String className)
inlineprotected

Internal method for creating a parameter dictionary for the class, if it does not already exist.

Remarks
This method will check to see if a parameter dictionary exist for this class yet, and if not will create one. NB you must supply the name of the class (RTTI is not used or performance).
Parameters
classNamethe name of the class using the dictionary
Returns
true if a new dictionary was created, false if it was already there

Definition at line 185 of file OgreStringInterface.h.

References OGRE_LOCK_MUTEX.

ParamDictionary* Ogre::StringInterface::getParamDictionary ( void  )
inline

Retrieves the parameter dictionary for this class.

Remarks
Only valid to call this after createParamDictionary.
Returns
Pointer to ParamDictionary shared by all instances of this class which you can add parameters to, retrieve parameters etc.

Definition at line 218 of file OgreStringInterface.h.

const ParamDictionary* Ogre::StringInterface::getParamDictionary ( void  ) const
inline

Definition at line 223 of file OgreStringInterface.h.

virtual String Ogre::StringInterface::getParameter ( const String name) const
inlinevirtual

Generic parameter retrieval method.

Remarks
Call this method with the name of a parameter to retrieve a string-format value of the parameter in question. If in doubt, check the parameter definition in the list returned from getParameters for the type of this parameter. If you like you can use StringConverter to convert this string back into a native type.
Parameters
nameThe name of the parameter to get
Returns
String value of parameter, blank if not found

const ParameterList& Ogre::StringInterface::getParameters ( void  ) const

Retrieves a list of parameters valid for this object.

Returns
A reference to a static list of ParameterDef objects.
Ogre::StringInterface::OGRE_STATIC_MUTEX ( msDictionaryMutex  )
private
virtual bool Ogre::StringInterface::setParameter ( const String name,
const String value 
)
virtual

Generic parameter setting method.

Remarks
Call this method with the name of a parameter and a string version of the value to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.
Parameters
nameThe name of the parameter to set
valueString value. Must be in the right format for the type specified in the parameter definition. See the StringConverter class for more information.
Returns
true if set was successful, false otherwise (NB no exceptions thrown - tolerant method)

Referenced by copyParametersTo().

virtual void Ogre::StringInterface::setParameterList ( const NameValuePairList paramList)
virtual

Generic multiple parameter setting method.

Remarks
Call this method with a list of name / value pairs to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.
Parameters
paramListName/value pair list
