public interface SequenceIterable
extends Serializable

This interface is a simple subset of the Expression interface, that provides a single method to evaluate the result of an expression as a sequence

Method Summary

SequenceIterator

iterate(XPathContext context) Return an iterator over the results of evaluating an expression

Method Detail

iterate

SequenceIterator iterate(XPathContext context)
                         throws XPathException

Return an iterator over the results of evaluating an expression

Parameters:

context - the dynamic evaluation context

Returns:

an iterator over the items delivered by the expression

Throws:

XPathException
