Constructor Detail

• public BitBuffer(int bytes)

  Creates a bit buffer of a specfied size. The buffer size cannot be changed after allocation.

  Parameters:

  bytes - number of bytes in the buffer

Method Detail

• public boolean eos()

  Checks if the read/write position is at the end of the buffer.

  Returns:

  true if position at end, false otherwise

• public byte[] getBytes()

  Gets an array of bytes in the buffer. Any modifications to the array are reflected as changes in the buffer.

  Returns:

  byte array of buffered data

• public int getSizeInBits()

  Gets the size of the buffer in bits.

  Returns:

  size in bits

• public int getSizeInBytes()

  Gets the size of the buffer in bytes.

  Returns:

  size in bytes

• public int read()

  Reads one bit of data from the buffer.

  Returns:

  bit (0 or 1) or -1 if end of stream

• public void reset()

  Resets the read/write position of the buffer to the start of the buffer.

• public void write(int bit)

  Writes one bit into the buffer.

  Parameters:

  bit - bit to write (0 or 1)

• public void write(byte[] data)

  Writes an array of bytes into the buffer. This method should not be called when an incompletely written byte exists in the buffer.

  Parameters:

  data - array of bytes to write
