method-message

method <-> message: code|host_method*

Implementation of the method object. This slot cooperates with the -function variable:

@nil In this case the -function is a pointer to a C-function implementing the method. This function will be passed the receiver and the arguments of the method. If the last type of the method denotes multiple arguments (...), the C-function will be passed an integer for the number of arguments and a pointer to an array of objects for the actual arguments. Internal use only.
host_method object An opaque handle, provided by the host language, that refers to a procedure in the host language. See also pce_predicate_reference/2.
A code object If the method is a get_method object, this must be a function object.
If the method is executed, @receiver points to the receiver of the message and @arg1, ... point to the arguments provided to the message. See also method->initialise.
