Open Object Rexx - Files
Interpreter Behaviour Source Files
This directory contains files used to implement the underlying ooRexx
object behaviour. The behaviour management includes generated class
identifiers, tables of statically defined tables, etc. Many of the
behaviour files are auto-generated during the build process from a master
XML file using XSLT transforms. These auto-generated files are checked in
to the SVN source tree, but are not intended to be directly altered.
The following is a partial list of the files to be found in this subdirectory.
- PrimitiveClasses.xml
- The master file defining all of the ooRexx classes (both externally
available and internal). Each ooRexx class that is allocated from the
ooRexx memory heap must be defined in PrimitiveClasses.xml.
- ClassTypeCodes.h
- The master header file that assigns numeric type codes to each of the
classes defined in PrimitiveClasses.xml. This file is generated by the
ClassTypeCodes.xsl transform file.
- PrimitiveBehaviourNames.h
- A header file that defines symbol mappings between individual
class behaviours and the global primitive behaviour array in
PrimitiveBehaviours.cpp. This file is generated by the
PrimitiveBehaviourNames.xsl transform file.
- PrimitiveBehaviours.cpp
- The master set of primitive behaviour objects that are referenced by
created class instances. This file is generated by the
PrimitiveBehaviours.xsl transform file.
- VirtualFunctionTable.cpp
- A static table of virtual function table pointers for each of the
ooRexx classes. This table is used for setting/restoring the C++ VFT
pointers in restored class instances. This file is generated by the
VirtualFunctionTable.xsl transform file.
- RexxBehaviour.*
- The implementation of the class that manages class identifier and
behaviour information. All ooRexx classes have an associated behaviour
object referenced from the header. For internal classes, this is
largely just class identification information. For fully exported
ooRexx classes, the behaviour object holds the method dictionary and
scope information.
