The mesh cache stores already loaded meshes and provides an interface to them.
You can access it using ISceneManager::getMeshCache(). All existing scene managers will return a pointer to the same mesh cache, because it is shared between them. With this interface, it is possible to manually add new loaded meshes (if ISceneManager::getMesh() is not sufficient), to remove them and to iterate through already loaded meshes.

Adds a mesh to the internal list of loaded meshes.
Usually, ISceneManager::getMesh() is called to load a mesh from a file. That method searches the list of loaded meshes if a mesh has already been loaded and returns a pointer to if it is in that list and already in memory. Otherwise it loads the mesh. With IMeshCache::addMesh(), it is possible to pretend that a mesh already has been loaded. This method can be used for example by mesh loaders who need to load more than one mesh with one call. They can add additional meshes with this method to the scene manager. The COLLADA loader for example uses this method.
name | Name of the mesh. When calling ISceneManager::getMesh() with this name it will return the mesh set by this method. |
mesh | Pointer to a mesh which will now be referenced by this name. |

Clears the whole mesh cache, removing all meshes.
All meshes will be reloaded completely when using ISceneManager::getMesh() after calling this method. Warning: If you have pointers to meshes that were loaded with ISceneManager::getMesh() and you did not grab them, then they may become invalid.

Returns amount of loaded meshes in the cache.
You can load new meshes into the cache using getMesh() and addMesh(). If you ever need to access the internal mesh cache, you can do this using removeMesh(), getMeshNumber(), getMeshByIndex() and getMeshName().

Removes the mesh from the cache.
After loading a mesh with getMesh(), the mesh can be removed from the cache using this method, freeing a lot of memory.

Note that renaming meshes might change the ordering of the meshes, and so the index of the meshes as returned by getMeshIndex() or taken by some methods will change.
