Constructor Detail

• ByteWriter

  public ByteWriter()

  Default constructor.

• ByteWriter

  public ByteWriter(int capacity)

  Constructor.

  Parameters:

  capacity - initial capacity of buffer

Method Detail

• getBytes

  public byte[] getBytes()

  Retrieve all of the bytes that have been written to this instance.

  Returns:

  byte content written so far (not necessarily a copy; caller must not modify)

• getBytes

  public byte[] getBytes(int off)

  Retrieve the bytes that have been written to this instance, starting at the given offset.

  Parameters:

  off - offset into written bytes

  Returns:

  byte content written so far starting at off (not necessarily a copy; caller must not modify)

  Throws:

  IndexOutOfBoundsException - if off or len is out of bounds

• getBytes

  public byte[] getBytes(int off,
                int len)

  Retrieve a sub-range of the bytes that have been written to this instance.

  Parameters:

  off - offset into written bytes

  len - desired length

  Returns:

  len bytes written so far starting from off (not necessarily a copy; caller must not modify)

  Throws:

  IndexOutOfBoundsException - if off or len is out of bounds

• writeByte

  public void writeByte(int value)

  Write a single byte to this instance.

  Parameters:

  value - byte to write; all but the lower 8 bits are ignored

• write

  public void write(ByteReader reader)

  Read all remaining content from the given ByteReader and write it to this instance.

  Parameters:

  reader - source for bytes to write

• write

  public void write(byte[] data)

  Write an array of bytes to this instance.

  Parameters:

  data - bytes to write

• write

  public void write(byte[] data,
           int off,
           int len)

  Write a sub-range from an array of bytes.

  Parameters:

  data - bytes to write

  off - offset into data

  len - the number of bytes to write

  Throws:

  IndexOutOfBoundsException - if off or len is out of bounds

• getLength

  public int getLength()

  Get the current buffer length. Returns the same value as #mark.

  Returns:

  number of bytes written so far

• mark

  public int mark()

  Mark current position. Returns the same value as #getLength.

  Returns:

  number of bytes written so far

• reset

  public void reset(int mark)

  Reset write position to a previously marked position.

  Parameters:

  mark - value previously returned by mark()

  Throws:

  IndexOutOfBoundsException - if mark is out of bounds
