Method Detail

getFunctionQName

public StructuredQName getFunctionQName()

Description copied from class: ExtensionFunctionDefinition

Get the name of the function, as a QName.

This method must be implemented in all subclasses

Specified by:

getFunctionQName in class ExtensionFunctionDefinition

Returns:

the function name

compute

protected SequenceIterator compute(SequenceIterator input,
                                   FunctionItem test,
                                   XPathContext context)

The function that does the work, which must be implemented in subclasses

Specified by:

compute in class SubsequenceTestFn

Parameters:

input - the input sequence

test - the function to be applied to the items in the sequence, which takes an item in the sequence as input and produces a boolean as its result

context - the XPath dynamic context

Returns:

the result
