void FileParser::finishTranslationUnit ( )
inlinevirtual

Called after all files in a translation unit have been processed.

Implements ParserInterface.

bool FileParser::needsPreprocessing ( const QCString extension)
inlinevirtual

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

virtual

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

Parameters
[in]codeOutIntfAbstract interface for writing the result.
[in]langThe programming language of the code fragment.
[in]scopeNameName of scope to which the code belongs.
[in]inputActual code in the form of a string
[in]isExampleBlockTRUE iff the code is part of an example.
[in]exampleNameName of the example.
[in]fileDefFile definition to which the code is associated.
[in]startLineStarting line in case of a code fragment.
[in]endLineEnding line of the code fragment.
[in]inlineFragmentCode fragment that is to be shown inline as part of the documentation.
[in]memberDefMember definition to which the code is associated (non null in case of an inline fragment for a member).
[in]showLineNumbersif set to TRUE and also fileDef is not 0, line numbers will be added to the source fragement
[in]searchCtxcontext under which search data has to be stored.
[in]collectXRefscollect cross-reference relations.

void FileParser::parseInput ( const char *  fileName,

bool  sameTranslationUnit,

)
inlinevirtual

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

Parameters
[in]fileNameThe full name of the file.
[in]fileBufThe contents of the file (zero terminated).
[in,out]rootThe root of the tree of Entry *nodes representing the information extracted from the file.
[in]sameTranslationUnitTRUE if this file was found in the same translation unit (in the filesInSameTranslationUnit list returned for another file).
[in,out]filesInSameTranslationUnitother files expected to be found in the same translation unit (used for libclang)

void FileParser::parsePrototype ( const char *  text)
inlinevirtual

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 ParserInterface.

Definition at line 46 of file fileparser.h.

void FileParser::resetCodeParserState ( )
inlinevirtual

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.

parseCode()

Implements ParserInterface.

Definition at line 45 of file fileparser.h.

45 {}
void FileParser::startTranslationUnit ( const char *  fileName)
inlinevirtual

Starts processing a translation unit (source files + headers). After this call parseInput() is called with sameTranslationUnit set to FALSE. If parseInput() returns additional include files, these are also processed using parseInput() with sameTranslationUnit set to TRUE. After that finishTranslationUnit() is called.
