Method Detail

readFully

public static void readFully(java.io.InputStream stream,
                             byte[] bytes,
                             int offset,
                             int length)
                      throws java.io.IOException

Reads into a buffer from a stream, making multiple read calls if necessary.

Parameters:

stream - an InputStream to read from

bytes - a buffer to write into

offset - starting offset in the buffer for the data

length - length of bytes to copy from the input stream to the buffer

Throws:

java.io.EOFException - if the end of the stream is reached before reading length bytes

java.io.IOException - if there is an error while reading

writeFully

public static void writeFully(java.io.OutputStream outputStream,
                              java.nio.ByteBuffer buffer)
                       throws java.io.IOException

Writes a buffer into a stream, making multiple write calls if necessary.

Throws:

java.io.IOException

readRemaining

public static int readRemaining(java.io.InputStream stream,
                                byte[] bytes,
                                int offset,
                                int length)
                         throws java.io.IOException

Reads into a buffer from a stream, making multiple read calls if necessary returning the number of bytes read until end of stream.

Parameters:

stream - an InputStream to read from

bytes - a buffer to write into

offset - starting offset in the buffer for the data

length - length of bytes to copy from the input stream to the buffer

Returns:

the number of bytes read

Throws:

java.io.IOException - if there is an error while reading
