the singleton object that stores information regarding this module.

invoke

void invoke(int index,
          ArgumentStack arguments)
            throws java.lang.Throwable

This method invokes a function within this module.

This is a low-level function needed to implement delegates.

The key is the index of the function in the list returned by moduleFunctions().

This method does nothing, iff the index does not refer to a real function.

Parameters:

index - identifies the function to invoke.

arguments - contains the arguments to pass to the function.

Throws:

java.lang.Throwable - Any unhandled exception thrown by the function will be rethrown.
