BytesMessage (src)
If the length of array value
is less than the number of
bytes remaining to be read from the stream, the array should
be filled. A subsequent call reads the next increment, and so on.
If the number of bytes remaining in the stream is less than the
length of
array value
, the bytes should be read into the array.
The return value of the total number of bytes read will be less than
the length of the array, indicating that there are no more bytes left
to be read from the stream. The next read of the stream returns -1.

be filled. A subsequent call reads the next increment, and so on.
If the number of bytes remaining in the stream is less than the

The return value of the total number of bytes read will be less than

If length
is negative, or
length
is greater than the length of the array
value
, then an IndexOutOfBoundsException
is
thrown. No bytes will be read from the stream for this exception case.
