Method Detail

makeOptionsParameter

public static OptionsParameter makeOptionsParameter()

call

public Sequence call(XPathContext context,
                     Sequence[] arguments)
              throws XPathException

Description copied from interface: Function

Invoke the function

Specified by:

call in interface Callable

Specified by:

call in interface Function

Parameters:

context - the XPath dynamic evaluation context

arguments - the actual arguments to be supplied

Returns:

the result of invoking the function

Throws:

XPathException - if a dynamic error occurs within the function

process

public void process(Outputter destination,
                    XPathContext context,
                    Sequence[] arguments)
             throws XPathException

Description copied from interface: PushableFunction

Evaluate the function in "push" mode

Specified by:

process in interface PushableFunction

Parameters:

destination - the destination for the function result

context - the dynamic evaluation context

arguments - the supplied arguments to the function

Throws:

XPathException - if a dynamic error occurs during the evaluation

getStreamerName

public java.lang.String getStreamerName()

Description copied from class: SystemFunction

Get a name that identifies the class that can be used to evaluate this function in streaming mode, that is, supplying one item or event at a time as it is delivered by the parser. Special streaming support is generally available in Saxon-EE for all system functions that take a sequence as their argument.

Overrides:

getStreamerName in class SystemFunction

Returns:

a name that identifies a class that supports streamed evaluation of this system function, or null if no such class is available. The mapping of names to classes is defined in the Saxon-EE class StreamerMap. In non-streaming Saxon editions (HE and PE) the method always returns null.
