Detailed Description

THis class is the interface for storing information about tokens and the token's class. It thus serves two purposes: first, it is used as the "list of all defined tokens" wherever this list is needed. Secondly, it stores the informatino taken from the token customization section.

Member Function Documentation

void ITokenSpec::setClassName ( const string & className ) [pure virtual]

Sets the token's class name. Reimplemented in TokenSpec. Referenced by ITokenSpec_setClassName().

void ITokenSpec::setInheritance ( const string & inheritance, const Position & pos ) [pure virtual]

Sets the token's class inheritance. Reimplemented in TokenSpec. Referenced by ITokenSpec_setInheritance().

void ITokenSpec::setPreambleCode ( const string & preambleCode, const Position & pos ) [pure virtual]

Sets the token's class preamble code. Reimplemented in TokenSpec. Referenced by ITokenSpec_setPreambleCode().

void ITokenSpec::addCodeBlock ( const string & block, const Position & pos ) [pure virtual]

Adds a njew block of user code to be merged into the token's class. Reimplemented in TokenSpec. Referenced by ITokenSpec_addCodeBlock().

void ITokenSpec::addToken ( const string & tokName, Tkinds tokKind, ReNode * regexp, const string & tokAction, const Position & pos ) throw (ParseException) [pure virtual]

Adds a new regular or skip token into the list. The token's id will be set to its position into the list. It is VERY important that the list keeps the tokens in their textual order (as they appeared into the input source), and thtat their ids are given in the same order. Exceptions: ParseException   if a token with the same name already exists in the list. Reimplemented in TokenSpec. Referenced by ScannerSpec::ScannerSpec().

void ITokenSpec::addToken ( const string & tokName, const Position & pos ) throw (ParseException) [pure virtual]

Adds a new special token into the list. For a special token, only the name and id are needed. Exceptions: ParseException   if a token with the same name already exists. Reimplemented in TokenSpec.

bool ITokenSpec::isToken ( const string & tokName ) [pure virtual]

Returns true if a tokenwith the given name exists in the list. Reimplemented in TokenSpec.

int ITokenSpec::getTokenId ( const string & tokName ) [pure virtual]

Returns the id of the oktne with the given name, or -1 if no token with that id is found into the list. Reimplemented in TokenSpec. Referenced by operator[]().

ITokenDesc & ITokenSpec::operator[] ( int tokid ) [pure virtual]

Returns a reference to an implementation-defined TokenDesc object that contains data about he token with the given id. invariant: &this[i].id() == i, for any vaild i. Reimplemented in TokenSpec.

ITokenDesc & ITokenSpec::operator[] ( const string & tokName ) [inline]

Definition at line 160 of file itoken_spec.hh.

int ITokenSpec::count ( ) [pure virtual]

Returns the number of tokens. Reimplemented in TokenSpec. Referenced by ScannerSpec::dump(), and LAnalyzer::makeLa().

void ITokenSpec::dump ( ostream & os ) const [pure virtual]

If DEBUG is enabled, this method will dump all the data currently contained into this spec into the given stream Reimplemented in TokenSpec. Referenced by ScannerSpec::dump().
