ur_rna.GUITester.ScriptParser

## Class ParseException

- java.lang.Object
- - java.lang.Throwable
  - - java.lang.Exception
    - - ur_rna.GUITester.ScriptParser.ParseException

- All Implemented Interfaces:
    java.io.Serializable
  Direct Known Subclasses:
    ParseFormatException

      public class ParseException
      extends java.lang.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.

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

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

    Modifier and Type | Method and Description
    --- | ---
    `private static java.lang.String` | `buildMessage(Token currentToken, int[][] expectedTokenSequences, java.lang.String[] tokenImage)` It uses "currentToken" and "expectedTokenSequences" to generate a parse error message and returns it.

- - ### Field Detail

    - #### 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.

    - #### EOL

          protected static java.lang.String EOL

      The end of line string for this machine.

    - #### 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.

    - #### serialVersionUID

          private static final long serialVersionUID

      The version identifier for this Serializable class. Increment only if the serialized form of the class changes.

        Constant Field Values

    - #### 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.

  - ### Constructor Detail

    - #### 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)

      Constructor with message.

    - #### ParseException

          public ParseException(java.lang.String message,
                                java.lang.Throwable cause)

      Constructor with message.

    - #### 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.

  - ### Method Detail

    - #### buildMessage

          private static java.lang.String buildMessage(Token currentToken,
                                                       int[][] expectedTokenSequences,
                                                       java.lang.String[] tokenImage)

      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) the correct error message gets displayed.
