Method Details

iterate

public SequenceIterator iterate(XPathContext c)
            throws XPathException
Return an Iterator to iterate over the values of a sequence. The value of every expression can be regarded as a sequence, so this method is supported for all expressions. This default implementation handles iteration for expressions that return singleton values: for non-singleton expressions, the subclass must provide its own implementation.
Specified by:
iterate in interface SequenceIterable
Overrides:
iterate in interface Expression
Parameters:
Returns:
a SequenceIterator that can be used to iterate over the result of the expression
Throws:
XPathException - if any dynamic error occurs evaluating the expression
