org.objectweb.jonathan.apis.resources.ChunkProvider

read

public int read(byte[] array,

                int length)
         throws IOException

Reads data from the message into an array of bytes. The default implementation uses the readByteArray() method.

array - the buffer into which the data is read.

Returns:

the actual number of bytes read.

Throws:

IOException - if an error occurs.

skip

Skips over and discards n bytes of data from this input stream. The skip method may, for a variety of reasons, end up skipping over some smaller number of bytes, possibly 0. The actual number of bytes skipped is returned.

The default implementation calls the skip(int) method.

Parameters:

the actual number of bytes skipped.

Throws:

IOException - if an I/O error occurs.
