Inheritance diagram for Puma::Parser:

Description

Generic parser abstraction.

Setups the parser components ready to be used for parsing an input file (see class Puma::Syntax, Puma::Builder, and Puma::Semantic).

The result of parsing a source file is the so-called translation unit (see class Puma::CTranslationUnit). It encapsulates the result of the syntactic and semantic analyses (syntax tree, semantic information database, preprocessor tree).

Constructor & Destructor Documentation

Parser()

Puma::Parser::Parser ( Syntax & x, Builder & b, Semantic & s )

inline

Constructor.

Parameters

x	The syntax analysis component.
b	The syntax tree builder.
s	The semantic analysis component.

Member Function Documentation

configure()

void Puma::Parser::configure

(

Config &

c

)

Configure the parser components.

Calls the corresponding configure methods of the parser components.

Parameters

c	The configuration settings.

parse()

CTranslationUnit * Puma::Parser::parse	(	Unit &	file,
		CProject &	p,
		int	pre_mode = 0,
		std::ostream &	os = std::cout )

Parse the given input file.

Supports different preprocessing modes. 0 means to pass the preprocessed tokens to the parser. 1 means to print the preprocessed tokens on stdout and to not parse at all. Mode 2 means the same as mode 1 except that the preprocessed tokens are not printed to stdout.

Parameters

file	The input file.
p	The source project information.
pre_mode	The preprocessing mode (0-2).
os	Preprocessor output stream if mode is 1.

Returns

A newly created object containing the parse results. To be destroyed by the caller.
