public SequenceIterator iterate(XPathContext context)
throws XPathException
iterate in interface Expressioniterate in class ComputedExpressioncontext - supplies the context for evaluation
XPathException - if any dynamic error occurs evaluating the
expression
public java.lang.Object map(Item item,
XPathContext context,
java.lang.Object info)
throws XPathException
map in interface MappingFunctionitem - The item to be mapped.
If context is supplied, this must be the same as context.currentItem().context - The processing context. This is supplied only for mapping constructs that
set the context node, position, and size. Otherwise it is null.info - Arbitrary information supplied by the creator of the MappingIterator. It must be
read-only and immutable for the duration of the iteration.
