parseCode()

void CCodeParser::parseCode ( OutputCodeList & codeOutList, const QCString & scopeName, const QCString & input, SrcLangExt lang, bool stripCodeComments, bool isExampleBlock, const QCString & exampleName = QCString(), const FileDef * fileDef = nullptr, int startLine = -1, int endLine = -1, bool inlineFragment = FALSE, const MemberDef * memberDef = nullptr, bool showLineNumbers = TRUE, const Definition * searchCtx = nullptr, bool collectXRefs = TRUE )

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]	isExampleBlock	TRUE iff the code is part of an example.
[in]	exampleName	Name of the example.
[in]	fileDef	File definition to which the code is associated.
[in]	startLine	Starting line in case of a code fragment.
[in]	endLine	Ending line of the code fragment.
[in]	inlineFragment	Code fragment that is to be shown inline as part of the documentation.
[in]	memberDef	Member definition to which the code is associated (non null in case of an inline fragment for a member).
[in]	showLineNumbers	if set to TRUE and also fileDef is not 0, line numbers will be added to the source fragment
[in]	searchCtx	context under which search data has to be stored.
[in]	collectXRefs	collect cross-reference relations.

Implements CodeParserInterface.

resetCodeParserState()

void CCodeParser::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.
