Detailed Description

Archive-handling class.

Remarks: An archive is a generic term for a container of files. This may be a filesystem folder, it may be a compressed archive, it may even be a remote location shared on the web. This class is designed to be subclassed to provide access to a range of file locations.

: Instances of this class are never constructed or even handled by end-user applications. They are constructed by custom ArchiveFactory classes, which plugins can register new instances of using ArchiveManager. End-user applications will typically use ResourceManager or ResourceGroupManager to manage resources at a higher level, rather than reading files directly through this class. Doing it this way allows you to benefit from OGRE's automatic searching of multiple file locations for the resources you are looking for.

Constructor & Destructor Documentation

Ogre::Archive::Archive	(	const String &	name,
		const String &	archType
	)

inline

Constructor - don't call direct, used by ArchiveFactory.

Definition at line 102 of file OgreArchive.h.

virtual Ogre::Archive::~Archive ( )

inlinevirtual

Default destructor.

Definition at line 107 of file OgreArchive.h.

Member Function Documentation

virtual DataStreamPtr Ogre::Archive::create ( const String & filename ) const

inlinevirtual

Create a new file (or overwrite one already there).

Note: If the archive is read-only then this method will fail.

Parameters

filename The fully qualified name of the file

Returns: A shared pointer to a DataStream which can be used to read / write the file.

Reimplemented in Ogre::ZipArchive, Ogre::FileSystemArchive, and Ogre::APKFileSystemArchive.

Definition at line 155 of file OgreArchive.h.

References Ogre::Exception::ERR_NOT_IMPLEMENTED, and OGRE_EXCEPT.

virtual bool Ogre::Archive::exists ( const String & filename )

pure virtual

Find out if the named file exists (note: fully qualified filename required)

Implemented in Ogre::ZipArchive, Ogre::FileSystemArchive, and Ogre::APKFileSystemArchive.

virtual StringVectorPtr Ogre::Archive::find	(	const String &	pattern,
		bool	recursive = `true`,
		bool	dirs = `false`
	)

pure virtual

Find all file or directory names matching a given pattern in this archive.

Note: This method only returns filenames, you can also retrieve other information using findFileInfo.

Parameters

pattern	The pattern to search for; wildcards (*) are allowed
recursive	Whether all paths of the archive are searched (if the archive has a concept of that)
dirs	Set to true if you want the directories to be listed instead of files

Returns: A list of filenames matching the criteria, all are fully qualified

Implemented in Ogre::ZipArchive, Ogre::FileSystemArchive, and Ogre::APKFileSystemArchive.

virtual FileInfoListPtr Ogre::Archive::findFileInfo	(	const String &	pattern,
		bool	recursive = `true`,
		bool	dirs = `false`
	)		const

pure virtual

Find all files or directories matching a given pattern in this archive and get some detailed information about them.

Parameters

pattern	The pattern to search for; wildcards (*) are allowed
recursive	Whether all paths of the archive are searched (if the archive has a concept of that)
dirs	Set to true if you want the directories to be listed instead of files

Returns: A list of file information structures for all files matching the criteria.

Implemented in Ogre::ZipArchive, Ogre::FileSystemArchive, and Ogre::APKFileSystemArchive.

virtual time_t Ogre::Archive::getModifiedTime ( const String & filename )

pure virtual

Retrieve the modification time of a given file.

Implemented in Ogre::ZipArchive, Ogre::FileSystemArchive, and Ogre::APKFileSystemArchive.

const String& Ogre::Archive::getName ( void ) const

inline

Get the name of this archive.

Definition at line 110 of file OgreArchive.h.

const String& Ogre::Archive::getType ( void ) const

inline

Return the type code of this Archive.

Definition at line 233 of file OgreArchive.h.

virtual bool Ogre::Archive::isCaseSensitive ( void ) const

pure virtual

Returns whether this archive is case sensitive in the way it matches files.

Implemented in Ogre::ZipArchive, Ogre::FileSystemArchive, and Ogre::APKFileSystemArchive.

virtual bool Ogre::Archive::isReadOnly ( ) const

inlinevirtual

Reports whether this Archive is read-only, or whether the contents can be updated.

Definition at line 134 of file OgreArchive.h.

virtual StringVectorPtr Ogre::Archive::list	(	bool	recursive = `true`,
		bool	dirs = `false`
	)

pure virtual

List all file names in the archive.

Note: This method only returns filenames, you can also retrieve other information using listFileInfo.

Parameters

recursive	Whether all paths of the archive are searched (if the archive has a concept of that)
dirs	Set to true if you want the directories to be listed instead of files

Returns: A list of filenames matching the criteria, all are fully qualified

Implemented in Ogre::ZipArchive, Ogre::FileSystemArchive, and Ogre::APKFileSystemArchive.

virtual FileInfoListPtr Ogre::Archive::listFileInfo	(	bool	recursive = `true`,
		bool	dirs = `false`
	)

pure virtual

List all files in the archive with accompanying information.

Parameters

recursive	Whether all paths of the archive are searched (if the archive has a concept of that)
dirs	Set to true if you want the directories to be listed instead of files

Returns: A list of structures detailing quite a lot of information about all the files in the archive.

Implemented in Ogre::ZipArchive, Ogre::FileSystemArchive, and Ogre::APKFileSystemArchive.

virtual void Ogre::Archive::load ( )

pure virtual

Loads the archive.

Remarks: This initializes all the internal data of the class.

Warning: Do not call this function directly, it is meant to be used only by the ArchiveManager class.

Implemented in Ogre::ZipArchive, Ogre::FileSystemArchive, and Ogre::APKFileSystemArchive.

virtual DataStreamPtr Ogre::Archive::open	(	const String &	filename,
		bool	readOnly = `true`
	)		const

pure virtual

Open a stream on a given file.

Note: There is no equivalent 'close' method; the returned stream controls the lifecycle of this file operation.

Parameters

filename	The fully qualified name of the file
readOnly	Whether to open the file in read-only mode or not (note, if the archive is read-only then this cannot be set to false)
