com.netscape.certsrv.util.AsyncLoader

public class AsyncLoader
extends java.lang.Object

A locking mechanism for loading or reloading an initially unknown number of items. The "producer" is the thread that loads items, informing the Loader when each item is loaded and how many items there are (when that fact becomes known). Other threads can await the completion of a (re)loading process.
