| TokenMgrError | | public class TokenMgrError extends Error (Code) | | |
| Field Summary | |
| final static int | INVALID_LEXICAL_STATE
Tried to change to an invalid lexical state. | | final static int | LEXICAL_ERROR
Lexical error occured. | | final static int | LOOP_DETECTED
Detected (and bailed out of) an infinite loop in the token manager. | | final static int | STATIC_LEXER_ERROR
An attempt wass made to create a second instance of a static token manager. | | int | errorCode
Indicates the reason why the exception is thrown. |
| Method Summary | |
| protected static String | LexicalError(boolean EOFSeen, int lexState, int errorLine, int errorColumn, String errorAfter, char curChar)

| | public String | getMessage()
You can also modify the body of this method to customize your error messages.
For example, cases like LOOP_DETECTED and INVALID_LEXICAL_STATE are not
of end-users concern, so you can return something like :
"Internal Error : Please file a bug report .... |
| INVALID_LEXICAL_STATE | | final static int INVALID_LEXICAL_STATE(Code) | | Tried to change to an invalid lexical state.

|
| LOOP_DETECTED | | final static int LOOP_DETECTED(Code) | | Detected (and bailed out of) an infinite loop in the token manager.
|
| STATIC_LEXER_ERROR | | final static int STATIC_LEXER_ERROR(Code) | | An attempt wass made to create a second instance of a static token manager.

curLexState : lexical state in which this error occured
errorLine : line number when the error occured
errorColumn : column number when the error occured
errorAfter : prefix that was seen before this error occured
curchar : the offending character
