Class ParseException

  • All Implemented Interfaces:
    java.io.Serializable
    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.

    Serialized Form

    • Field Summary

      Fields 
      Modifier and Type Field 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 Summary

      Constructors 
      Constructor 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​(Token currentTokenVal, int[][] expectedTokenSequencesVal, java.lang.String[] tokenImageVal)
      This constructor is used by the method "generateParseException" in the generated parser.

    • Method Summary

      All Methods Static Methods Concrete Methods 
      Modifier and Type Method Description
      (package private) static 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.
      private static java.lang.String initialise​(Token currentToken, int[][] expectedTokenSequences, java.lang.String[] tokenImage)
      It uses "currentToken" and "expectedTokenSequences" to generate a parse error message and returns it.

      • 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

      • EOL

        protected static java.lang.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 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.

    • 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.

      • 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.

    • Method Detail

      • initialise

        private static java.lang.String initialise​(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.

      • add_escapes

        static 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.
