Member Function Documentation
| virtual const char* ml::ListParser::getErrorMessage | ( | int | errorCode | ) | [virtual] |
Get error string for errorCode.
Reimplemented from ml::ParserBase.

| virtual int ml::ListParser::init | ( | const char * | source | ) | [virtual] |
Initialize parser and proceed to first character of first item.
Return codes:
- kEmptyString for an empty or null source string,
- kEndOfSource for an empty list ("[]")
- kMissingOpenBracket for a non-empty string not beginning with '['
- kMissingCloseBracket for a string containing only "["

| static bool ml::ListParser::needsQuote | ( | char * | itemStr | ) | [static] |
Return true if itemStr needs to be quoted.
| int ml::ListParser::nextItemString | ( | char *& | itemString | ) |
Set itemString to next item's substring Return codes:
- kEndOfSource if no next item exists
- kMissingCloseBracket if string ends without closing bracket
- Any return code of unquoteString()

| static char* ml::ListParser::quoteString | ( | char * | itemStr | ) | [static] |
Return a quoted copy of itemStr allocated on the heap.
| int ml::ListParser::unquoteString | ( | std::string & | itemString | ) | [protected] |
Convert quoted string to original, unescaped character sequence Assumes that _pNext points to a leading quote, proceeds to the first character after the terminating quote.
Return kUnmatchedQuote if strings ends without terminating quote.
