  • Constructor Details

    • Dumper

      public Dumper​(int addressOffset)
      Construct a new Dumper.
      Parameters:
      addressOffset - int; address for the first byte that will be appended

    • Dumper

      public Dumper()
      Construct a new Dumper with addressOffset 0.

  • Method Details

    • setOutputStream

      public Dumper<T> setOutputStream​(OutputStream newOutputStream)
      Set or replace the active output stream. (The default output stream is System.out.)
      Parameters:
      newOutputStream - OutputStream; the new output stream
      Returns:
      Dumper<T>; this Dumper object (for method chaining)

    • setSuppressMultipleIdenticalLines

      public Dumper<T> setSuppressMultipleIdenticalLines​(boolean newState)
      Set the output compression mode.
      Parameters:
      newState - boolean; if true; groups of three or more output lines with the significant content are compressed; if false; no output is suppressed
      Returns:
      Dumper<T>; this Dumper object (for method chaining)

    • addDecoder

      public void addDecoder​(Decoder decoder)
      Add a Decoder at the end of the current list of decoders.
      Parameters:
      decoder - Decoder; the decoder to add or insert

    • addDecoder

      public Dumper<T> addDecoder​(int index, Decoder decoder) throws IndexOutOfBoundsException
      Add a Decoder at a specified index.
      Parameters:
      index - int; the position where the Decoder must be added (inserted)
      decoder - Decoder; the decoder to add or insert
      Returns:
      Dumper<T>; this Dumper object (for method chaining)
      Throws:
      IndexOutOfBoundsException - when the provided index is invalid

    • append

      public boolean append​(byte theByte) throws IOException
      Append one byte to this dump.
      Parameters:
      theByte - byte; the byte to append
      Returns:
      boolean; true if output was generated; false if the byte was accumulated, but did not result in immediate output
      Throws:
      IOException - when output was generated and writing to the output stream generated an IOException

    • append

      public Dumper<T> append​(byte[] bytes) throws IOException
      Append an array of bytes.
      Parameters:
      bytes - byte[]; the bytes to append
      Returns:
      Dumper<T>; this Dumper object (for method chaining)
      Throws:
      IOException - when an outputStream has been set and it throws an IOException

    • append

      public Dumper<T> append​(byte[] bytes, int start, int len) throws IOException
      Append a slice of an array of bytes.
      Parameters:
      bytes - byte[]; byte array from which to take the bytes to append
      start - int; index of first byte in bytes to append (NB. using non-zero does not cause a jump in the address that is printed before the dumped bytes)
      len - int; number of bytes to append
      Returns:
      Dumper<T>; this Dumper object (for method chaining)
      Throws:
      IOException - when an outputStream has been set and it throws an IOException

    • append

      public Dumper<T> append​(InputStream inputStream) throws IOException
      Consume an entire input stream and append what it produces to this Dumpmer. The input stream is not closed by this append method. This method does not return until the inputStream returns end of file, or throws an IOException (which is - actually - not a return to the caller, but a jump to the closest handler for that exception).
      Parameters:
      inputStream - InputStream; the input stream that is to be consumed
      Returns:
      Dumper<T>; this Dumper object (for method chaining)
      Throws:
      IOException - when the inputStream throws that exception, or when an output stream has been set and that throws an IOException

    • flush

      public boolean flush() throws IOException
      Force the currently assembled output to be written (write partial result if the output line currently being assembled is not full).
      Returns:
      boolean; true if output was generated; false if no output was generated
      Throws:
      IOException - when output was generated and writing to the output stream generated an IOException

    • getMaximumWidth

      public int getMaximumWidth()
      Return the maximum width of an output line.
      Returns:
      int; the maximum width of an output line

    • toString

      public String toString()
      Overrides:
      toString in class Object
