public SequenceIterator map(XPathContext context)
                     throws XPathException

Map one item to a sequence.

Specified by:

map in interface ContextMappingFunction

Parameters:

context - The processing context. Some mapping functions use this because they require context information. Some mapping functions modify the context by maintaining the context item and position. In other cases, the context may be null.

Returns:

either (a) a SequenceIterator over the sequence of items that the supplied input item maps to, or (b) an Item if it maps to a single item, or (c) null if it maps to an empty sequence.

Throws:

XPathException - if a dynamic error is detected
