Class DocumentDeleteThread

java.lang.Object
  java.lang.Thread
      org.apache.manifoldcf.crawler.system.DocumentDeleteThread

All Implemented Interfaces:

java.lang.Runnable

public class DocumentDeleteThread
extends java.lang.Thread

This class represents a document delete thread. This thread's job is to pull document sets to be deleted off of a queue, and kill them. It finishes a delete set by getting rid of the corresponding rows in the job queue. There are very few decisions that this thread needs to make; essentially all the hard thought went into deciding what documents to queue in the first place. The only caveat is that the ingestion API may not be accepting delete requests at the time that this thread wants it to be able to accept them. In that case, it's acceptable for the thread to block until the ingestion service is functioning again. Transactions are not much needed for this class; it simply needs to not fail to remove the appropriate jobqueue table rows at the end of the delete.
