Data Members

Name	Description
compilerGeneratedStatementQueue	compiler generated code statements are pushed into a temporary queue so that they can be output after any statements attached to the next statements and before the next statement
cur	This is a cursor mechanism which is not encapsulated into the curprint() member function.
cur_index	used to index the preprocessor list
currentFile
delegate	delegate unparser that can be used to replace the output of this unparser
opt	holds all desired options for this unparser
prevdir_was_cppDeclaration	The previous directive was a CPP statment (otherwise it was a comment)

Description

This class represents the backend C++ code generator within ROSE. It is separated from the AST IR so that it can be more easily developed as a separate modular piece of ROSE.

This is the source code generator. It traverses the AST (not using the newer traversal mechanisms) and generates C++ source code from the constructs within the AST. Special attention is given to formatting the generated code.

Note: Large parts of documentation contained in ROSE/src/unparser.docs.

Internal: This class could be simplified now that comments and CPP directives are a part of the AST.

Metadata: ‐ Authors: Lee, Quinlan, Schordan, ... ‐ Version: 0.5 cvs‐version‐#: _Name: _ ‐ Date: _Date: 2006/04/24 00:21:29 _ ‐ Bug: No known bugs. ‐ Warning: Formatting still overly complex (can be simplified now that comments are part of the AST). ‐ TODO: Finish documentation; make formatting easily tailorable to different styles (low priority at the moment).
