Class RefCountingBLOBFileValue

java.lang.Object
  org.apache.jackrabbit.core.value.RefCountingBLOBFileValue

All Implemented Interfaces:

Binary

public class RefCountingBLOBFileValue
extends Object

RefCountingBLOBFileValue implements a reference counting BLOB file value on top of an existing BLOBFileValue. Whenever a copy() is created from this BLOB file value, a new light weight RefCountBinary is created and the reference count refCount is incremented. The underlying value is discarded once this RefCountingBLOBFileValue and all its light weight RefCountBinary intances have been discarded.

Constructor Summary

RefCountingBLOBFileValue(org.apache.jackrabbit.core.value.BLOBFileValue value)
