  • SharedByteArrayInputStream

    public SharedByteArrayInputStream(byte[] buf)

    Create a SharedByteArrayInputStream representing the entire byte array.

    Parameters:

    buf - the byte array

  • SharedByteArrayInputStream

    public SharedByteArrayInputStream(byte[] buf,
     int offset,
     int length)

    Create a SharedByteArrayInputStream representing the part of the byte array from offset for length bytes.

    Parameters:

    buf - the byte array

    offset - offset in byte array to first byte to include

    length - number of bytes to include

• Method Detail

  • getPosition

    public long getPosition()

    Return the current position in the InputStream, as an offset from the beginning of the InputStream.

    Specified by:

    getPosition in interface SharedInputStream

    Returns:

    the current position

  • newStream

    public InputStream newStream(long start,
     long end)

    Return a new InputStream representing a subset of the data from this InputStream, starting at start (inclusive) up to end (exclusive). start must be non-negative. If end is -1, the new stream ends at the same place as this stream. The returned InputStream will also implement the SharedInputStream interface.

    Specified by:

    newStream in interface SharedInputStream

    Parameters:

    start - the starting position

    end - the ending position + 1

    Returns:

    the new stream
