20 * Describes the input token stream.
26 * An integer that describes the kind of this token. This numbering
27 * system is determined by JavaCCParser, and a table of these numbers is
28 * stored in the file ...Constants.java.
33 * beginLine and beginColumn describe the position of the first character
34 * of this token; endLine and endColumn describe the position of the
35 * last character of this token.
37 public int beginLine, beginColumn, endLine, endColumn;
40 * The string image of the token.
45 * A reference to the next regular (non-special) token from the input
46 * stream. If this is the last token from the input stream, or if the
47 * token manager has not read tokens beyond this one, this field is
48 * set to null. This is true only if this token is also a regular
49 * token. Otherwise, see below for a description of the contents of
55 * This field is used to access special tokens that occur prior to this
56 * token, but after the immediately preceding regular (non-special) token.
57 * If there are no such special tokens, this field is set to null.
58 * When there are more than one such special token, this field refers
59 * to the last of these special tokens, which in turn refers to the next
60 * previous special token through its specialToken field, and so on
61 * until the first special token (whose specialToken field is null).
62 * The next fields of special tokens refer to other special tokens that
63 * immediately follow it (without an intervening regular token). If there
64 * is no such token, this field is null.
66 public Token specialToken;
71 public String toString()
77 * Returns a new Token object, by default. However, if you want, you
78 * can create and return subclass objects based on the value of ofKind.
79 * Simply add the cases to the switch for all those special cases.
80 * For example, if you have a subclass of Token called IDToken that
81 * you want to create if ofKind is ID, simlpy add something like :
83 * case MyParserConstants.ID : return new IDToken();
85 * to the following switch statement. Then you can cast matchedToken
86 * variable to the appropriate type and use it in your lexical actions.
