Dylan Language Stub Mapping

This document present a proposed mapping of Dylan to the CORBA IDL.

There are 8 basic tasks, each of which occupies one section.

1) All IDL basic types.

2) All IDL constructed data types.

3) References to constants defined in IDL.

4) References to objects defined in IDL.

5) Invocations of operations, including passing parameters and
receiving results.

6) Exceptions, including what happens when an operation raises an
exception and how the exception parameters are accessed.

7) Access to attributes.

8) Signatures for the operations defined by the ORB, such as the
dynamic invocation interface, the object adapters.

===============================================================================

1)  Data Type Mappings

IDL				Dylan class

short				limited (<integer> min: - expt(2 15)
						   max: expt(2 15) - 1)

long				limited (<integer> min: - expt(2 31)
						   max: expt(2 31) - 1)

unsigned short			limited (<integer> min: 0
						   max: expt(2 16) - 1)

unsigned long			limited (<integer> min: 0
					 	   max: expt(2 32) - 1)

float				<single-float> (IEEE single precision)

double				<double-float> (IEEE double precision)

char				<character> transmission conversion allowed

boolean				union (singleton(#t) singleton (#f))

octet				<character>* no transmission conversion

enum				limited (<integer> min: 0
						   max: expt(2 32) - 1)

any				<object>

2) Constructed Data Types.

a) An IDL Structure is a Dylan <class>

b) An IDL Union 

c) Enumeration

3) Constants

IDL constants are Dylan <singletons> (and C #define's).
