public abstract class ExtensionFunctionCall
An instance of this class will be created by the compiler for each function call to this extension function that is found in the source code. The implementation may therefore retain information about the static context of the call. Once compiled, however, the instance object must be immutable.

public void SupplyStaticContext(StaticContext context)
Method called by the compiler (at compile time) to provide information about the static context of the function call. The implementation may retain this information for use at run-time, if the result of the function depends on information in the static context.
For efficiency, the implementation should only retain copies of the information that it actually needs. It is not a good idea to hold a reference to the static context itself, since that can result in a great deal of compile-time information being locked into memory during run-time execution.
Parameters:context
-
public void CopyLocalData(ExtensionFunctionCall destination)
A subclass must implement this method if it retains any local data at the instance level. On some occasions
(for example, when XSLT or XQuery code is inlined), Saxon will make a copy of an ExtensionFunction
object.
It will then call this method on the old object, supplying the new object as the value of the argument, and the
method must copy all local data items from the old object to the new.
