java.lang.Objectorg.jboss.util.collection.WeakTypeCache<T>
T
- the cached typepublic abstract class WeakTypeCache<T>
A weak class cache that instantiates does not a hold a strong reference to either the classloader or class.
It creates the class specific data in two stages to avoid recursion.
instantiate - creates the data
generate - fills in the details
