Uses of WeakIdentityMap in org.eclipse.persistence.internal.identitymaps

Subclasses of WeakIdentityMap in org.eclipse.persistence.internal.identitymaps

Modifier and Type	Class	Description
class	HardCacheWeakIdentityMap	Purpose: A HardCacheWeakIdentityMap is identical to the weak identity map, however the weak reference can be a performance problem for some types of apps because it can cause too much garbage collection of objects read causing them to be re-read and re-built (this defeats the purpose of the cache).
class	SoftCacheWeakIdentityMap	Purpose: A SoftCacheWeakIdentityMap is identical to the WeakIdentityMap, however the weak reference can be a performance problem for some types of apps because it can cause too much garbage collection of objects read causing them to be re-read and re-built (this defeats the purpose of the cache).
class	SoftIdentityMap	Purpose: A SoftIdentityMap holds all objects referenced by the application.
