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

Sets the token's class name.
Reimplemented from ITokenSpec.
Definition at line 49 of file token_spec.cc.

void TokenSpec::setInheritance ( const string & inheritance,

const Position & pos ) [virtual]

Sets the token's class inheritance.
Reimplemented from ITokenSpec.
Definition at line 55 of file token_spec.cc.

void TokenSpec::setPreambleCode ( const string & preambleCode,

const Position & pos ) [virtual]

Sets the token's class preamble code.
Reimplemented from ITokenSpec.
Definition at line 63 of file token_spec.cc.

void TokenSpec::addCodeBlock ( const string & block,

const Position & pos ) [virtual]

Adds a njew block of user code to be merged into the token's class.
Reimplemented from ITokenSpec.
Definition at line 71 of file token_spec.cc.

void TokenSpec::addToken ( const string & tokName,

Tkinds tokKind,

ReNode * regexp,

const string & tokAction,

const Position & pos ) throw (ParseException) [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 from ITokenSpec.
Definition at line 76 of file token_spec.cc.

void TokenSpec::addToken ( const string & tokName,

const Position & pos ) throw (ParseException) [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 from ITokenSpec.
Definition at line 88 of file token_spec.cc.

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

Returns true if a tokenwith the given name exists in the list.
Reimplemented from ITokenSpec.
Definition at line 103 of file token_spec.cc.

int TokenSpec::getTokenId ( const string & tokName ) [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 from ITokenSpec.
Definition at line 109 of file token_spec.cc.

TokenDesc & TokenSpec::operator[] ( int tokid ) [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 from ITokenSpec.
Definition at line 118 of file token_spec.cc.

int TokenSpec::count ( ) [virtual]

Returns the number of tokens.
Reimplemented from ITokenSpec.
Definition at line 125 of file token_spec.cc.
Referenced by ScannerDfaWriter::writeScanner(), and TokenWriter::writeTokenClass().

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

If DEBUG is enabled, this method will dump all the data currently contained into this spec into the given stream
Reimplemented from ITokenSpec.
Definition at line 134 of file token_spec.cc.
