All Implemented Interfaces:

Runnable

Enclosing class:

SequenceExchanger

public static class SequenceExchanger.EvaluationThread
extends SequenceExchanger.Producer

EvaluationThread is a producer that evaluates an expression in "push" mode, writing the results to a Conduit.

Constructor Summary

SequenceExchanger.EvaluationThread(Expression exp, PipelineConfiguration pipe, XPathContext context, Conduit conduit)
Create an EvaluationThread

Method Summary

SequenceExchanger.Producer	getAnother(Conduit conduit) Make a copy of this Producer, evaluating the expression again starting at the beginning, and writing the results to a new Conduit
void	run() Run the thread, evaluating the expression and writing its results to the Conduit
