parseCode()

void PythonCodeParser::parseCode ( OutputCodeList & codeOutList, const QCString & scopeName, const QCString & input, SrcLangExt lang, bool stripCodeComments, const CodeParserOptions & options )

overridevirtual

Parses a source file or fragment with the goal to produce highlighted and cross-referenced output.

Parameters

[in]	codeOutList	interface for writing the result.
[in]	scopeName	Name of scope to which the code belongs.
[in]	input	Actual code in the form of a string
[in]	lang	The programming language of the code fragment.
[in]	stripCodeComments	signals whether or not for the code block the doxygen comments should be stripped.
[in]	options	Additional options to configure the parser.

Implements CodeParserInterface.

resetCodeParserState()

void PythonCodeParser::resetCodeParserState ( )

overridevirtual

Resets the state of the code parser.

Since multiple code fragments can together form a single example, an explicit function is used to reset the code parser state.
