public Class UnsharedNameTable

extends Utf8NameTable
Class Inheritance
Imports
java.lang.ref.WeakReference
Implementation of Name.Table that stores names in individual arrays using weak references. It is recommended for use when a single shared byte array is unsuitable.

This is NOT part of any supported API. If you write code that depends on this, you do so at your own risk. This code and its internal interfaces are subject to change or deletion without notice.
