Class AbstractParseException

          java.lang.Exception
              java.lang.RuntimeException

public class AbstractParseException
extends java.lang.RuntimeException

The `AbstractParseException` represents a parse exception that was thrown by one of the parsers generated by JavaCC. It is the supertype of all generated ParseException classes so that they can be unified here.

  Serialized Form

Field Summary
`AbstractToken` | `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.
`ProgramPoint` | `programPoint`
`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
`AbstractParseException()` The following constructors are for use by you for whatever purpose you can think of.
`AbstractParseException(AbstractToken currentTokenVal, int[][] expectedTokenSequencesVal, java.lang.String[] tokenImageVal)` This constructor is used by the method "generateParseException" in the generated parser.
`AbstractParseException(java.lang.String message)`

Method Summary
`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.

Methods inherited from class java.lang.Throwable

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 AbstractToken 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.

### programPoint

    public ProgramPoint programPoint

Constructor Detail

### AbstractParseException

    public AbstractParseException(AbstractToken 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:

### AbstractParseException

    public AbstractParseException()

  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.

### AbstractParseException

    public AbstractParseException(java.lang.String message)

Method Detail

### 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.
