Class CswsConnector.ExecuteMethodThread

java.lang.Object

java.lang.Thread

org.apache.manifoldcf.crawler.connectors.csws.CswsConnector.ExecuteMethodThread

All Implemented Interfaces:

java.lang.Runnable

Enclosing class:

CswsConnector

protected static class CswsConnector.ExecuteMethodThread
extends java.lang.Thread

This thread does the actual socket communication with the server. It's set up so that it can be abandoned at shutdown time. The way it works is as follows: - it starts the transaction - it receives the response, and saves that for the calling class to inspect - it transfers the data part to an input stream provided to the calling class - it shuts the connection down If there is an error, the sequence is aborted, and an exception is recorded for the calling class to examine. The calling class basically accepts the sequence above. It starts the thread, and tries to get a response code. If instead an exception is seen, the exception is thrown up the stack.
