      public FixedString(String fixedResult)
      Construct a Decoder that returns a fixed result in the getResult method.
      Parameters:
      fixedResult - the String that the getResult method will return on each invocation

  • Method Details

    • getResult

      public String getResult()
      Description copied from interface: Decoder
      Retrieve the current result of this Decoder. Decoders that handle multiple byte input may be somewhere within a token. Such Decoders should report a partial result. If no data has been added, the result must be the empty string.
      Specified by:
      getResult in interface Decoder
      Returns:
      the current result of this Decoder

    • getMaximumWidth

      public int getMaximumWidth()
      Description copied from interface: Decoder
      Retrieve the maximum width (in characters) of results that this Decoder can return (all shorter results will be padded to this width with spaces, unless this is the last active Decoder).
      Specified by:
      getMaximumWidth in interface Decoder
      Returns:
      the maximum width (in characters) of results that this Decoder can return

    • append

      public boolean append(int address, byte theByte)
      Description copied from interface: Decoder
      Decode one (more) byte. This method must return true when a line becomes full due to this call, otherwise this method must return false.
      Specified by:
      append in interface Decoder
      Parameters:
      address - the address that corresponds with the byte
      theByte - the byte
      Returns:
      true if an output line has been completed by this call; false if at least one more byte can be appended to the local accumulator before the current output line is full

    • ignoreForIdenticalOutputCheck

      public boolean ignoreForIdenticalOutputCheck()
      Description copied from interface: Decoder
      If the result of this Decoder should not be used to compare output lines for suppressing identical lines, this method should return true; otherwise it should return false.
      Specified by:
      ignoreForIdenticalOutputCheck in interface Decoder
      Returns:
      true if the result of this Decoder should be ignored in testing for identical output lines; otherwise false

    • toString

      public String toString()
      Overrides:
      toString in class Object
