Class BlockingDocuments

java.lang.Object
  org.apache.manifoldcf.crawler.interfaces.BlockingDocuments

public class BlockingDocuments
extends java.lang.Object

An instance of this class keeps track of a pool of documents that the stuffer thread believes are ready to be reprioritized. The way it works is that when the stuffer sees documents that it can't use, but which it thinks are eligible from reprioritization, it hands them to this object. The prioritization thread then takes documents out of this queue and prioritizes them, before it goes looking for other documents. This process guarantees that the stuffer is not blocked by documents that need reprioritization.
