Method Detail

meta_pass

public ATObject meta_pass()
                   throws InterpreterException

By reference objects serialize to a proxy representation. This proxy representation takes the form of a far reference to the local object.

Specified by:

meta_pass in interface ATObject

Overrides:

meta_pass in class NATNil

Throws:

InterpreterException

meta_resolve

public ATObject meta_resolve()
                      throws InterpreterException

By reference objects cannot be deserialized, by definition. It is an error to try to resolve an unserializable by reference object. The object on which meta_resolve is normally invoked is the proxy representation that was returned by this object's meta_pass method.

Specified by:

meta_resolve in interface ATObject

Overrides:

meta_resolve in class NATNil

Throws:

InterpreterException
