public void supplyStaticContext(StaticContext context,
- Supply static context information.
This method is called during compilation to provide information about the static context in which
the function call appears. If the implementation of the function needs information from the static context,
then it should save it now, as it will not be available later at run-time.
The implementation also has the opportunity to examine the expressions that appear in the
arguments to the function call at this stage. These might already have been modified from the original
expressions as written by the user. The implementation should not modify any of these expressions.
The default implementation of this method does nothing.
supplyStaticContext in class
context - The static context in which the function call appears. The method must not modify
the static context.
locationId - An integer code representing the location of the call to the extension function
in the stylesheet; can be used in conjunction with the locationMap held in the static context for diagnostics
arguments - The XPath expressions supplied in the call to this function. The method must not
modify this array, or any of the expressions contained in the array.
XPathException - if the implementation is able to detect a static error in the way the
function is being called (for example it might require that the types of the arguments are
consistent with each other).
public void copyLocalData(ExtensionFunctionCall destination)
- Copy local data from one copy of the function to another. This method must be implemented
in any implementation that maintains local data retained from the static context; the job of the
method is to copy this local data to the supplied destination function.
copyLocalData in class
destination - the function to which the local data must be copied. This will always
be an instance of the same function class as the source function.
