Member Function Documentation

◆ needsPreprocessing()

bool LexOutlineParser::needsPreprocessing ( const DString & extension ) const

inlineoverridevirtual

Returns true if the language identified by extension needs the C preprocessor to be run before feed the result to the input parser.

See also: parseInput()

Implements OutlineParserInterface.

Definition at line 35 of file lexscanner.h.

35{ return true; }

◆ parseInput()

void LexOutlineParser::parseInput	(	const DString &	fileName,
		const char *	fileBuf,
		const std::shared_ptr< Entry > &	root,
		ClangTUParser *	clangParser )

overridevirtual

Parses a single input file with the goal to build an Entry tree.

Parameters

[in]	fileName	The full name of the file.
[in]	fileBuf	The contents of the file (zero terminated).
[in,out]	root	The root of the tree of Entry *nodes representing the information extracted from the file.
[in]	clangParser	The clang translation unit parser object or nullptr if disabled.

Implements OutlineParserInterface.

  struct yyguts_t *yyg = (struct yyguts_t*)p->yyscanner;
 
  yyextra->fileName      = fileName;
  DebugLex debugLex(Debug::Lex_lexscanner, __FILE__, qPrint(fileName));
 
  ::parseMain(p->yyscanner,fileName,fileBuf,root,clangParser);
}

◆ parsePrototype()

void LexOutlineParser::parsePrototype ( const DString & text )

inlineoverridevirtual

Callback function called by the comment block scanner.

It provides a string text containing the prototype of a function or variable. The parser should parse this and store the information in the Entry node that corresponds with the node for which the comment block parser was invoked.

Implements OutlineParserInterface.
