public interface CloneableSmartAsset
extends java.lang.Cloneable

Implementing the CloneableSmartAsset interface allows use of cloneable smart asset management.

Smart asset management requires cooperation from the AssetKey. In particular, the AssetKey should return WeakRefCloneAssetCache in its AssetKey.getCacheType() method. Also smart assets MUST create a clone of the asset and cannot return the same reference, e.g. createClone(someAsset) != someAsset.

If the AssetManager.loadAsset(com.jme3.asset.AssetKey) method is called twice with the same asset key (equals() wise, not necessarily reference wise) then both assets will have the same asset key set (reference wise) via AssetKey(), then this asset key is used to track all instances of that asset. Once all clones of the asset are garbage collected, the shared asset key becomes unreachable and at that point it is removed from the smart asset cache.

Method Summary

Modifier and Type	Method and Description
CloneableSmartAsset	clone() Creates a clone of the asset.
AssetKey	getKey() Returns the asset key that is used to track this asset for garbage collection.
void	setKey(AssetKey key) Set by the AssetManager to track this asset.

Method Detail

clone

CloneableSmartAsset clone()

Creates a clone of the asset. Please see Object.clone() for more info on how this method should be implemented.

Returns:

A clone of this asset. The cloned asset cannot reference equal this asset.

setKey

void setKey(AssetKey key)

Set by the AssetManager to track this asset. Only clones of the asset has this set, the original copy that was loaded has this key set to null so that only the clones are tracked for garbage collection.

Parameters:

key - The AssetKey to set

getKey

AssetKey getKey()

Returns the asset key that is used to track this asset for garbage collection.

Returns:

the asset key that is used to track this asset for garbage collection.
