ByteArrayDataInputStream

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

ByteArrayDataInputStream

public ByteArrayDataInputStream(java.nio.ByteBuffer buffer)

Method Detail

position

public ByteArrayDataInputStream position(int pos)

position

public int position()

limit

public int limit()

capacity

public int capacity()

read

public int read()

Reads the next byte of data from buf. The value byte is returned as an int in the range 0 to 255. If no byte is available because the end of the buffer has been reached, the value -1 is returned.

Returns:

the next byte of data, or -1 if the end of the stream has been reached.
