Constructor & Destructor Documentation

ParserBase()

ml::ParserBase::ParserBase ( )

inline

Constructor.

Definition at line 41 of file mlParserBase.h.

~ParserBase()

virtual ml::ParserBase::~ParserBase ( )

inlinevirtual

Make destructor virtual to avoid warnings.

Definition at line 44 of file mlParserBase.h.

Member Function Documentation

deleteString()

static void ml::ParserBase::deleteString ( char *  str )

static

Dispose a string allocated with newString()

Referenced by ml::ListBase::deleteString().

endOfSource()

bool ml::ParserBase::endOfSource ( )

inline

Return end-of-source flag.

Definition at line 54 of file mlParserBase.h.

getCurrentPos()

const char * ml::ParserBase::getCurrentPos ( )

inline

Get current parser position.

Definition at line 51 of file mlParserBase.h.

getErrorMessage()

virtual const char * ml::ParserBase::getErrorMessage ( int  errorCode )

virtual

Get error string for errorCode.

Reimplemented in ml::BaseItemParser, and ml::ListParser.

init()

virtual int ml::ParserBase::init ( const char *  source )

virtual

Initialize parser and proceed to first non-whitespace character.

Returns kEmptyString for an empty or null source string.

Reimplemented in ml::ListParser.

newString()

static char * ml::ParserBase::newString ( const std::string &  str )

static

Convenience method to create a copy of the string str allocated on the heap.

This avoids passing STL strings between modules, which fails in Windows due to a bug in the VC++ implementation of the STL.

Referenced by ml::ListBase::newString().

skipWhitespace()

void ml::ParserBase::skipWhitespace ( )

protected

Proceed to next non-whitespace character.

Member Data Documentation

_eos

bool ml::ParserBase::_eos

protected

End-of-string flag.

Definition at line 88 of file mlParserBase.h.

_pNext

const char* ml::ParserBase::_pNext

protected

Pointer to current parser position.

Definition at line 86 of file mlParserBase.h.

_source

const char* ml::ParserBase::_source

protected

Source string.

Definition at line 84 of file mlParserBase.h.
