Class HessianFreeList<T>

java.lang.Object
com.caucho.hessian.util.HessianFreeList<T>

public final class HessianFreeList<T> extends Object
FreeList provides a simple class to manage free objects. This is useful for large data structures that otherwise would gobble up huge GC time.

The free list is bounded. Freeing an object when the list is full will do nothing.
