- All Implemented Interfaces: 
- Serializable
- public class ParseException- extends Exception
This exception is thrown when parse errors are encountered. You can
 explicitly create objects of this exception type by calling the method
 generateParseException in the generated parser.
 
 You can modify this class to customize your error reporting mechanisms so
 long as you retain the public fields.

specialConstructor
protected boolean specialConstructor
- This variable determines which constructor was used to create this object
 and thereby affects the semantics of the "getMessage" method (see below).
currentToken
public Token currentToken
- This is the last token that has been consumed successfully. If this
 object has been created due to a parse error, the token followng this
 token will (therefore) be the first error token.
expectedTokenSequences
public int[][] expectedTokenSequences
- Each entry in this array is an array of integers. Each array of integers
 represents a sequence of tokens (by their ordinal values) that is
 expected at this point of the parse.
tokenImage
public String[] tokenImage
- This is a reference to the "tokenImage" array of the generated parser
 within which the parse error occurred. This array is defined in the
 generated ...Constants interface.
eol
protected String eol
- The end of line string for this machine.
ParseException
public ParseException(Token currentTokenVal,
                      int[][] expectedTokenSequencesVal,
                      String[] tokenImageVal)
- This constructor is used by the method "generateParseException" in the
 generated parser. Calling this constructor generates a new object of this
 type with the fields "currentToken", "expectedTokenSequences", and
 "tokenImage" set. The boolean flag "specialConstructor" is also set to
 true to indicate that this constructor was used to create this object.
 This constructor calls its super class with the empty string to force the
 "toString" method of parent class "Throwable" to print the error message
 in the form: ParseException: (result of getMessage)
ParseException
public ParseException()
- The following constructors are for use by you for whatever purpose you
 can think of. Constructing the exception in this manner makes the
 exception behave in the normal way - i.e., as documented in the class
 "Throwable". The fields "errorToken", "expectedTokenSequences", and
 "tokenImage" do not contain relevant information. The JavaCC generated
 code does not use these constructors.
ParseException
public ParseException(String message)
getMessage
public String getMessage()
- This method has the standard behavior when this object has been created
 using the standard constructors. Otherwise, it uses "currentToken" and
 "expectedTokenSequences" to generate a parse error message and returns
 it. If this object has been created due to a parse error, and you do not
 catch it (it gets thrown from the parser), then this method is called
 during the printing of the final stack trace, and hence the correct error
 message gets displayed.- 
- Overrides:
- getMessagein class- Throwable
 
add_escapes
protected String add_escapes(String str)
- Used to convert raw characters to their escaped version when these raw
 version cannot be used as part of an ASCII string literal.
