Method Details

addClassLoader

public void addClassLoader(ClassLoader loader)

Description copied from interface: AssetManager

Adds a ClassLoader that is used to load classes that are needed for finding and loading Assets. This does not allow loading assets from that classpath, use registerLocator for that.

Specified by:

addClassLoader in interface AssetManager

Parameters:

loader - A ClassLoader that Classes in asset files can be loaded from.

removeClassLoader

public void removeClassLoader(ClassLoader loader)

Description copied from interface: AssetManager

Remove a ClassLoader from the list of registered ClassLoaders

Specified by:

removeClassLoader in interface AssetManager

Parameters:

loader - the ClassLoader to be removed

public List<ClassLoader> getClassLoaders()

Description copied from interface: AssetManager

Retrieve the list of registered ClassLoaders that are used for loading classes from asset files.

Specified by:

getClassLoaders in interface AssetManager

Returns:

an unmodifiable list

addAssetEventListener

public void addAssetEventListener(AssetEventListener listener)

Description copied from interface: AssetManager

Add an AssetEventListener to receive events from this AssetManager.

Specified by:

addAssetEventListener in interface AssetManager

Parameters:

listener - The asset event listener to add

removeAssetEventListener

public void removeAssetEventListener(AssetEventListener listener)

Description copied from interface: AssetManager

Remove an AssetEventListener from receiving events from this AssetManager

Specified by:

removeAssetEventListener in interface AssetManager

Parameters:

listener - The asset event listener to remove

clearAssetEventListeners

Description copied from interface: AssetManager

Removes all asset event listeners.

Specified by:

clearAssetEventListeners in interface AssetManager

• AssetManager.addAssetEventListener(com.jme3.asset.AssetEventListener)

setAssetEventListener

public void setAssetEventListener(AssetEventListener listener)

registerLoader

public void registerLoader(Class<? extends AssetLoader> loader,
 String... extensions)

Description copied from interface: AssetManager

Register an AssetLoader by using a class object.

Specified by:

registerLoader in interface AssetManager

Parameters:

loader - The loader class to register.

extensions - Which extensions this loader is responsible for loading, if there are already other loaders registered for that extension, they will be overridden - there should only be one loader for each extension.

registerLoader

public void registerLoader(String clsName,
 String... extensions)

unregisterLoader

public void unregisterLoader(Class<? extends AssetLoader> loaderClass)

Description copied from interface: AssetManager

Unregister a AssetLoader from loading its assigned extensions. This undoes the effect of calling AssetManager.registerLoader(java.lang.Class, java.lang.String[]).

Specified by:

unregisterLoader in interface AssetManager

Parameters:

loaderClass - The loader class to unregister.

See Also:

• AssetManager.registerLoader(java.lang.Class, java.lang.String[])

registerLocator

public void registerLocator(String rootPath,
 Class<? extends AssetLocator> locatorClass)

Description copied from interface: AssetManager

Registers the given locator class for locating assets with this AssetManager. AssetLocators are invoked in the order they were registered, to locate the asset by the AssetKey. Once an AssetLocator returns a non-null AssetInfo, it is sent to the AssetLoader to load the asset. Once a locator is registered, it can be removed via AssetManager.unregisterLocator(java.lang.String, java.lang.Class).

Specified by:

registerLocator in interface AssetManager

Parameters:

rootPath - Specifies the root path from which to locate assets for the given AssetLocator. The purpose of this parameter depends on the type of the AssetLocator.

locatorClass - The class type of the AssetLocator to register.

See Also:

• AssetLocator.setRootPath(java.lang.String)
• AssetLocator.locate(com.jme3.asset.AssetManager, com.jme3.asset.AssetKey)
• AssetManager.unregisterLocator(java.lang.String, java.lang.Class)

registerLocator

public void registerLocator(String rootPath,
 String clsName)

unregisterLocator

public void unregisterLocator(String rootPath,
 Class<? extends AssetLocator> clazz)

Description copied from interface: AssetManager

Unregisters the given locator class. This essentially undoes the operation done by AssetManager.registerLocator(java.lang.String, java.lang.Class).

Specified by:

unregisterLocator in interface AssetManager

Parameters:

rootPath - Should be the same as the root path specified in AssetManager.registerLocator(java.lang.String, java.lang.Class).

clazz - The locator class to unregister

See Also:

• AssetManager.registerLocator(java.lang.String, java.lang.Class)

locateAsset

public AssetInfo locateAsset(AssetKey<?> key)

Description copied from interface: AssetManager

Manually locates an asset with the given AssetKey. This method should be used for debugging or internal uses.
The call will attempt to locate the asset by invoking the AssetLocator that are registered with this AssetManager, in the same way that the AssetManager.loadAsset(com.jme3.asset.AssetKey) method locates assets.

Specified by:

locateAsset in interface AssetManager

Parameters:

key - The AssetKey to locate.

The AssetInfo object returned from the AssetLocator that located the asset, or null if the asset cannot be located.

Specified by:

getFromCache in interface AssetManager

Type Parameters:

T - The object type that will be retrieved from the AssetKey instance.

Parameters:

key - The AssetKey to get from the cache.

Returns:

The cached asset, if found. Otherwise, null.

addToCache

public <T> void addToCache(AssetKey<T> key,
 T asset)

Description copied from interface: AssetManager

Inject an asset into the asset cache. NOTE: Do not modify the cached asset after storing! It is the same reference as what is stored in the cache, therefore any modifications to it will leak onto assets loaded from the same key in the future.

Specified by:

addToCache in interface AssetManager

Type Parameters:

T - The object type of the asset.

Parameters:

key - The key where the asset shall be stored.

asset - The asset to inject into the cache.

deleteFromCache

Description copied from interface: AssetManager

Delete an asset from the asset cache.

Specified by:

deleteFromCache in interface AssetManager

Type Parameters:

T - The object type of the AssetKey instance.

Parameters:

key - The asset key to remove from the cache.

Returns:

True if the asset key was found in the cache and was removed successfully. False if the asset key was not present in the cache.
