## Class ParseException

- java.lang.Object
- - java.lang.Throwable
  - - java.lang.Exception
    - - bsh.EvalError
      - - bsh.ParseException

- All Implemented Interfaces:
    java.io.Serializable

      public class ParseException
      extends EvalError

  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.

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

  - ### Constructor Summary

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

  - ### Method Summary

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `protected java.lang.String` | `add_escapes(java.lang.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.
    `int` | `getErrorLineNumber()`
    `java.lang.String` | `getErrorSourceFile()`
    `java.lang.String` | `getErrorText()`
    `java.lang.String` | `getMessage()`
    `java.lang.String` | `getMessage(boolean debug)` This method has the standard behavior when this object has been created using the standard constructors.
    `void` | `setErrorSourceFile(java.lang.String file)` Used to add source file info to exception
    `java.lang.String` | `toString()` Print the error with line number and stack trace.

- - ### Field Detail

    - #### 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 java.lang.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 java.lang.String eol

      The end of line string for this machine.

  - ### Constructor Detail

    - #### ParseException

          public ParseException(Token currentTokenVal,
                        int[][] expectedTokenSequencesVal,
                        java.lang.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:

    - #### 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(java.lang.String message)

  - ### Method Detail

    - #### setErrorSourceFile

          public void setErrorSourceFile(java.lang.String file)

      Used to add source file info to exception

    - #### getErrorSourceFile

          public java.lang.String getErrorSourceFile()

      Overrides:
        `getErrorSourceFile` in class `EvalError`

    - #### getMessage

          public java.lang.String getMessage()

      Overrides:
        `getMessage` in class `EvalError`
      See Also:
        `for a full display of the information`

    - #### getMessage

          public java.lang.String getMessage(boolean debug)

      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.

    - #### add_escapes

          protected java.lang.String add_escapes(java.lang.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.

    - #### getErrorLineNumber

          public int getErrorLineNumber()

      Overrides:
        `getErrorLineNumber` in class `EvalError`

    - #### getErrorText

          public java.lang.String getErrorText()

      Overrides:
        `getErrorText` in class `EvalError`

    - #### toString

          public java.lang.String toString()

      Description copied from class: `EvalError`
      Print the error with line number and stack trace.
      Overrides:
        `toString` in class `EvalError`
