Member Function Documentation
| static void ml::ParserBase::deleteString | ( | char * | str | ) | [static] |
Dispose a string allocated with newString().
| bool ml::ParserBase::endOfSource | ( | ) | [inline] |
| const char* ml::ParserBase::getCurrentPos | ( | ) | [inline] |
| virtual const char* ml::ParserBase::getErrorMessage | ( | int | errorCode | ) | [virtual] |
| 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.
| 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.
| void ml::ParserBase::skipWhitespace | ( | ) | [protected] |
Proceed to next non-whitespace character.
