+ 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).

sThe semantic analysis component.

Member Function Documentation

void Puma::Parser::configure ( Config c)

Configure the parser components.

Calls the corresponding configure methods of the parser components.

Parameters
cThe configuration settings.
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
fileThe input file.
pThe source project information.
pre_modeThe preprocessing mode (0-2).
osPreprocessor output stream if mode is 1.
Returns
A newly created object containing the parse results. To be destroyed by the caller.
