Method Detail

init

protected void init()

Initialize the set of functions available

Overrides:

init in class VendorFunctionLibraryPE

copy

public FunctionLibrary copy()

Description copied from class: IntegratedFunctionLibrary

This method creates a copy of a FunctionLibrary: if the original FunctionLibrary allows new functions to be added, then additions to this copy will not affect the original, or vice versa.

Specified by:

copy in interface FunctionLibrary

Overrides:

copy in class VendorFunctionLibraryPE

Returns:

a copy of this function library. This must be an instance of the original class.

bind

public Expression bind(SymbolicName symbolicName,
              Expression[] staticArgs,
              StaticContext env)
                throws XPathException

Bind an extension function, given the URI and local parts of the function name, and the list of expressions supplied as arguments. This method is called at compile time.

Specified by:

bind in interface FunctionLibrary

Overrides:

bind in class VendorFunctionLibraryPE

Parameters:

symbolicName - the name and arity of the function

staticArgs - The expressions supplied statically in the function call. The intention is that the static type of the arguments (obtainable via getItemType() and getCardinality() may be used as part of the binding algorithm.

env - The static context

Returns:

An object representing the extension function to be called, if one is found; null if no extension function was found matching the required name and arity.

Throws:

XPathException - if a function is found with the required name and arity, but the implementation of the function cannot be loaded or used; or if an error occurs while searching for the function; or if this function library "owns" the namespace containing the function call, but no function was found.
