- All Known Implementing Classes:
public interface ContextMappingFunctionContextMappingFunction is an interface that must be satisfied by an object passed to a ContextMappingIterator. It represents an object which, given an Item, can return a SequenceIterator that delivers a sequence of zero or more Items.
This is a specialization of the more general MappingFunction class: it differs in that each item being processed becomes the context item while it is being processed.
SequenceIterator map(XPathContext context) throws XPathExceptionMap one item to a sequence.
context- The processing context. The item to be mapped is the context item identified from this context: the values of position() and last() also relate to the set of items being mapped
- a SequenceIterator over the sequence of items that the supplied input item maps to
XPathException- if a dynamic error is detected
