## Constructor & Destructor Documentation

Ogre::ArchiveManager::ArchiveManager | ( |  | ) |

Definition at line 54 of file OgreArchiveManager.h.

Default destructor.

## Member Function Documentation

Archive* Ogre::ArchiveManager::load | ( | const String & | filename,
|  | const String & | archiveType |
| ) |  |  |

Opens an archive for file reading.

Remarks:
  The archives are created using class factories within extension libraries.

Parameters:

  | filename | The filename that will be opened
  | refLibrary | The library that contains the data-handling code

Returns:
  If the function succeeds, a valid pointer to an Archive object is returened.

  If the function fails, an exception is thrown.

void Ogre::ArchiveManager::unload | ( | Archive * | arch | ) |

Unloads an archive.

Remarks:
  You must ensure that this archive is not being used before removing it.

void Ogre::ArchiveManager::unload | ( | const String & | filename | ) |

Unloads an archive by name.

Remarks:
  You must ensure that this archive is not being used before removing it.

void Ogre::ArchiveManager::addArchiveFactory | ( | ArchiveFactory * | factory | ) |

Adds a new ArchiveFactory to the list of available factories.

Remarks:
  Plugin developers who add new archive codecs need to call this after defining their ArchiveFactory subclass and Archive subclasses for their archive type.

static ArchiveManager& Ogre::ArchiveManager::getSingleton | ( | void |  | ) | `[static]`

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.

Reimplemented from Ogre::Singleton< T >.

static ArchiveManager* Ogre::ArchiveManager::getSingletonPtr | ( | void |  | ) | `[static]`
