Class FreeList

    java.lang.Object
      |
      +--com.caucho.util.FreeList

public final class FreeList
extends java.lang.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.

Constructor Summary
`FreeList(int initialSize)` Create a new free list.

Method Summary
`java.lang.Object` | `allocate()` Try to get an object from the free list.
`boolean` | `allowFree(java.lang.Object obj)`
`void` | `free(java.lang.Object obj)` Frees the object.
