iterate
public SequenceIterator iterate(XPathContext context) throws XPathException
Iterator over the results of the expression- Overrides:
iterate
in classExpression
- Parameters:
context
- supplies the context for evaluation- 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
-
sequenceIterator
public SequenceIterator sequenceIterator(java.util.Iterator<NamespaceBinding> iter, XPathContext context)
-
call
public SequenceIterator call(SequenceIterator[] arguments, XPathContext context) throws XPathException
Description copied from interface:CallableExpression
Evaluate the expression- Specified by:
call
in interfaceCallableExpression
- Parameters:
arguments
- the values of the arguments, supplied as SequenceIteratorscontext
- the dynamic evaluation context- Returns:
- the result of the evaluation, in the form of a SequenceIterator
- Throws:
XPathException
- if a dynamic error occurs during the evaluation of the expression
