Class Pipe

com.ziclix.python.sql.pipe.Pipe

public class Pipe
extends java.lang.Object

Manager for a Sink and Source. The Pipe creates a Queue through which the Source can feed data to the Sink. Both Sink and Source run in their own thread and can are completely independent of the other. When the Source pushes None onto the Queue, the piping is stopped and the Sink finishes processing all the remaining data. This class is especially useful for loading/copying data from one database or table to another.
