public Expression bind(StructuredQName functionName,
Expression[] staticArgs,
StaticContext env,
Container container)
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.

- Overrides:
bind
in class IntegratedFunctionLibrary
- Parameters:

- 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.
