| Token | | public class Token (Code) | | Describes the input token stream.
|
| Field Summary | |
| public int | beginLinebeginColumnendLineendColumn
beginLine and beginColumn describe the position of the first character of this token; endLine and endColumn
describe the position of the last character of this token. | | public String | image
The string image of the token. | | public int | kind
An integer that describes the kind of this token. | | public Token | next
A reference to the next regular (non-special) token from the input stream. | | public 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. |
| Method Summary | |
| final public static Token | newToken(int ofKind)
Returns a new Token object, by default. | | public String | toString()
Returns the image. |
| beginLinebeginColumnendLineendColumn | | public int beginLinebeginColumnendLineendColumn(Code) | | beginLine and beginColumn describe the position of the first character of this token; endLine and endColumn
describe the position of the last character of this token.
|
| image | | public String image(Code) | | The string image of the token.
|
| kind | | public int kind(Code) | | 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.
|
| next | | public Token next(Code) | | 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.
|
| specialToken | | public Token specialToken(Code) | | 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.
|
| newToken | | final public static Token newToken(int ofKind)(Code) | | 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, simlpy add something like : case
MyParserConstants.ID : return new IDToken(); to the following switch statement. Then you can cast matchedToken
variable to the appropriate type and use it in your lexical actions.
