INTERFACEThe netobj package uses specific subclasses of Pickle.Reader and Pickle.Writer to pickle object parameters. If you need to handle netobj pickling differently than other kinds of pickling, you can use these routines to check if the pickle is being used as a network object parameter or return value.NetObjF ; IMPORT NetObj, Pickle2 AS Pickle, Thread;
PROCEDURE IsNetObjWriter(wr: Pickle.Writer): BOOLEAN; PROCEDURE IsNetObjReader(wr: Pickle.Reader): BOOLEAN;We want to be able to pass an identifier for a network object between machines outside of the network object system.
ToWireRep
converts a NetObj.T into a wire representation and a text string
describing the location of the object. FromWireRep converts a
wire representation and location back into a NetObj.T. If the
corresponding network object (or a surrogate) does not already
exist in the process, FromWireRep will raise NetObj.Error if it
cannot be retreived from loc.
TYPE WRep = RECORD byte: ARRAY [0..15] OF BITS 8 FOR [0..255]; END;
