org.j3d.texture
Interface TextureCacheFactory

public interface TextureCacheFactory

Abstract representation of what a factory for texture caches would look like.

Different types of cache implementations are allowed (ie different ways of deciding when an texture no longer needs to be in the cache).

The factory also supports the concept of the "default cache". This is used when you want a simple system that doesn't really care about the cache type used and just wants to use this class as a global singleton for storing the texture information. The default cache type can be controlled through either directly setting the value in this class, or using a system property. By defining a value for the property

   org.j3d.texture.DefaultCacheType
 

with one of the values (case-sensitive) fixed, lru or weakref. Setting the type through the method call will override this setting. However, the cache type can only be set once. All further attempts will result in an exception.
