Member Function Documentation

◆ needsPreprocessing()

bool FortranOutlineParser::needsPreprocessing ( const QCString & extension ) const

overridevirtual

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 3377 of file fortranscanner.l.

{
  return extension!=extension.lower(); // use preprocessor only for upper case extensions
}

References QCString::lower().

◆ parseInput()

void FortranOutlineParser::parseInput	(	const QCString &	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.

  ::parseMain(p->yyscanner,fileName,fileBuf,root,p->format);
}

◆ parsePrototype()

void FortranOutlineParser::parsePrototype ( const QCString & text )

overridevirtual

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.
