public abstract class AsynchronousAssetLoader<T,P extends AssetLoaderParameters<T>>
extends AssetLoader<T,P>

Base class for asynchronous AssetLoader instances. Such loaders try to load parts of an OpenGL resource, like the Pixmap, on a separate thread to then load the actual resource on the thread the OpenGL context is active on.

Method Detail

loadAsync

public abstract void loadAsync(AssetManager manager,
                               java.lang.String fileName,
                               FileHandle file,
                               P parameter)

Loads the non-OpenGL part of the asset and injects any dependencies of the asset into the AssetManager.

Parameters:

manager -

fileName - the name of the asset to load

file - the resolved file to load

parameter - the parameters to use for loading the asset

unloadAsync

public void unloadAsync(AssetManager manager,
                        java.lang.String fileName,
                        FileHandle file,
                        P parameter)

Called if this task is unloaded before loadSync is called. This method may be invoked on any thread, but will not be invoked during or after loadSync. This method is not invoked when a task is cancelled because it threw an exception, only when the asset is unloaded before loading is complete.

The default implementation does nothing. Subclasses should release any resources acquired in loadAsync, which may or may not have been called before this method, but never during or after this method. Note that loadAsync may still be executing when this method is called and must release any resources it allocated.

loadSync

public abstract T loadSync(AssetManager manager,
                           java.lang.String fileName,
                           FileHandle file,
                           P parameter)

Loads the OpenGL part of the asset.

Parameters:

manager -

fileName -

file - the resolved file to load

parameter -
