Dokumentation der Elementfunktionen

getValue()

Object de.lathanda.eos.interpreter.parser.en.Token.getValue

(

)

An optional attribute value of the Token. Tokens which are not used as syntactic sugar will often contain meaningful values that will be used later on by the compiler or interpreter. This attribute value is often different from the image. Any subclass of Token that actually wants to return a non-null value can override this method as appropriate.

Definiert in Zeile 71 der Datei Token.java.

newToken() [1/2]

static Token de.lathanda.eos.interpreter.parser.en.Token.newToken ( int  ofKind )

static

Definiert in Zeile 125 der Datei Token.java.

newToken() [2/2]

static Token de.lathanda.eos.interpreter.parser.en.Token.newToken ( int  ofKind, String  image  )

static

Returns a new Token object, by default. However, if you want, you can create and return subclass objects based on the value of ofKind. Simply add the cases to the switch for all those special cases. For example, if you have a subclass of Token called IDToken that you want to create if ofKind is ID, simply add something like :

case MyParserConstants.ID : return new IDToken(ofKind, image);

to the following switch statement. Then you can cast matchedToken variable to the appropriate type and use sit in your lexical actions.

Definiert in Zeile 117 der Datei Token.java.

toString()

String de.lathanda.eos.interpreter.parser.en.Token.toString

(

)

Returns the image.

Definiert in Zeile 100 der Datei Token.java.

Dokumentation der Datenelemente

beginColumn

int de.lathanda.eos.interpreter.parser.en.Token.beginColumn

The column number of the first character of this Token.

Definiert in Zeile 28 der Datei Token.java.

beginLine

int de.lathanda.eos.interpreter.parser.en.Token.beginLine

The line number of the first character of this Token.

Definiert in Zeile 26 der Datei Token.java.

endColumn

int de.lathanda.eos.interpreter.parser.en.Token.endColumn

The column number of the last character of this Token.

Definiert in Zeile 32 der Datei Token.java.

endLine

int de.lathanda.eos.interpreter.parser.en.Token.endLine

The line number of the last character of this Token.

Definiert in Zeile 30 der Datei Token.java.

image

String de.lathanda.eos.interpreter.parser.en.Token.image

The string image of the token.

Definiert in Zeile 37 der Datei Token.java.

kind

int de.lathanda.eos.interpreter.parser.en.Token.kind

An integer that describes the kind of this token. This numbering system is determined by JavaCCParser, and a table of these numbers is stored in the file ...Constants.java.

Definiert in Zeile 23 der Datei Token.java.

next

Token de.lathanda.eos.interpreter.parser.en.Token.next

A reference to the next regular (non-special) token from the input stream. If this is the last token from the input stream, or if the token manager has not read tokens beyond this one, this field is set to null. This is true only if this token is also a regular token. Otherwise, see below for a description of the contents of this field.

Definiert in Zeile 47 der Datei Token.java.

specialToken

Token de.lathanda.eos.interpreter.parser.en.Token.specialToken

This field is used to access special tokens that occur prior to this token, but after the immediately preceding regular (non-special) token. If there are no such special tokens, this field is set to null. When there are more than one such special token, this field refers to the last of these special tokens, which in turn refers to the next previous special token through its specialToken field, and so on until the first special token (whose specialToken field is null). The next fields of special tokens refer to other special tokens that immediately follow it (without an intervening regular token). If there is no such token, this field is null.

Definiert in Zeile 61 der Datei Token.java.
