All Implemented Interfaces:
Serializable

Field Summary
static final int	LEXICAL_ERROR	Lexical error occured.
static final int	STATIC_LEXER_ERROR	An attempt wass made to create a second instance of a static token manager.
static final int	INVALID_LEXICAL_STATE	Tried to change to an invalid lexical state.
static final int	LOOP_DETECTED	Detected (and bailed out of) an infinite loop in the token manager.
int	errorCode	Indicates the reason why the exception is thrown. It will have one of the above 4 values.

Constructor:
public TokenMgrError() { }
public TokenMgrError(String message, int reason) { super(message); errorCode = reason; }
public TokenMgrError(boolean EOFSeen, int lexState, int errorLine, int errorColumn, String errorAfter, char curChar, int reason) { this(LexicalError(EOFSeen, lexState, errorLine, errorColumn, errorAfter, curChar), reason); }

Constructor:

 public TokenMgrError() {

}

 public TokenMgrError(String message,
    int reason) {
      super(message);
      errorCode = reason;
}

 public TokenMgrError(boolean EOFSeen,
    int lexState,
    int errorLine,
    int errorColumn,
    String errorAfter,
    char curChar,
    int reason) {
      this(LexicalError(EOFSeen, lexState, errorLine, errorColumn, errorAfter, curChar), reason);

Method from com.lowagie.text.pdf.codec.postscript.TokenMgrError Detail:
protected static final String addEscapes(String str) { StringBuffer retval = new StringBuffer(); char ch; for (int i = 0; i < str.length(); i++) { switch (str.charAt(i)) { case 0 : continue; case '\b": retval.append("\\b"); continue; case '\t": retval.append("\\t"); continue; case '\n": retval.append("\\n"); continue; case '\f": retval.append("\\f"); continue; case '\r": retval.append("\\r"); continue; case '\"": retval.append("\\\""); continue; case '\'": retval.append("\\\'"); continue; case '\\": retval.append("\\\\"); continue; default: if ((ch = str.charAt(i)) < 0x20 \|\| ch > 0x7e) { String s = "0000" + Integer.toString(ch, 16); retval.append("\\u" + s.substring(s.length() - 4, s.length())); } else { retval.append(ch); } continue; } } return retval.toString(); } Replaces unprintable characters by their espaced (or unicode escaped) equivalents in the given string
public String getMessage() { return super.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 .... " from this method for such cases in the release version of your parser.
