# Class ParseException

java.lang.Object
java.lang.Throwable
java.lang.Exception
org.apfloat.calc.ParseException

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.

- ## Field Summary

  Fields
  Modifier and Type
  Field
  Description
  `Token`
  `currentToken`
  This is the last token that has been consumed successfully.
  `protected static String`
  `EOL`
  The end of line string for this machine.
  `int[][]`
  `expectedTokenSequences`
  Each entry in this array is an array of integers.
  `String[]`
  `tokenImage`
  This is a reference to the "tokenImage" array of the generated parser within which the parse error occurred.

  Description
  `ParseException()`
  The following constructors are for use by you for whatever purpose you can think of.
  `ParseException(String message)`
  Constructor with message.
  `ParseException(Token currentTokenVal, int[][] expectedTokenSequencesVal, String[] tokenImageVal)`
  This constructor is used by the method "generateParseException" in the generated parser.

- ## Method Summary

  ### Methods inherited from class Throwable

  `addSuppressed, fillInStackTrace, getCause, getLocalizedMessage, getMessage, getStackTrace, getSuppressed, initCause, printStackTrace, printStackTrace, printStackTrace, setStackTrace, toString`

  ### Methods inherited from class Object

  `clone, equals, finalize, getClass, hashCode, notify, notifyAll, wait, wait, wait`

- ## Field Details

  - ### EOL

    protected static String EOL
    The end of line string for this machine.

  - ### 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 following 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.

- ## Constructor Details

  - ### 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.

  - ### 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)
    Constructor with message.
