IBlaubotConnectionint in the range 0 to
255. If no byte is available because the end of the stream
has been reached, the value -1 is returned. This method
blocks until input data is available, the end of the stream is detected,
or an exception is thrown.
A subclass must provide an implementation of this method.-1 if the end of the

IBlaubotConnectionb. The number of
bytes actually read is returned as an integer. This method blocks
until input data is available, end of file is detected, or an
exception is thrown.
If b is null, a NullPointerException is
thrown. If the length of b is zero, then no bytes are
read and 0 is returned; otherwise, there is an attempt
to read at least one byte. If no byte is available because the
stream is at end of file, the value -1 is returned;
otherwise, at least one byte is read and stored into b.
The first byte read is stored into element b[0], the
next one into b[1], and so on. The number of bytes read
is, at most, equal to the length of b. Let k
be the number of bytes actually read; these bytes will be stored in
elements b[0] through b[k-1], leaving
elements b[k] through b[b.length-1]
unaffected.
The read(b) method has the same effect as:
read(b, 0, b.length)

of the stream has been reached.java.io.IOException - if the first byte cannot be read for any reason
other than end of file, the stream has been closed and the underlying
input stream does not support reading after close, or another I/O
error occurs.java.net.SocketTimeoutException - if the socket timed outFilterInputStream.in,

IBlaubotConnectionlen bytes of data from the contained
input stream into an array of bytes. An attempt is made to read
as many as len bytes, but a smaller number may be read,
possibly zero. The number of bytes actually read is returned as an
integer.
This method blocks until input data is available, end of file is detected, or an exception is thrown.
If len is zero, then no bytes are read and
0 is returned; otherwise, there is an attempt to read at
least one byte. If no byte is available because the stream is at end of
file, the value -1 is returned; otherwise, at least one
byte is read and stored into b.
The first byte read is stored into element b[off], the
next one into b[off+1], and so on. The number of bytes read
is, at most, equal to len. Let k be the number of
bytes actually read; these bytes will be stored in elements
b[off] through b[off+k-1],
leaving elements b[off+k] through
b[off+len-1] unaffected.
In every case, elements b[0] through
b[off] and elements b[off+len] through
b[b.length-1] are unaffected.

IBlaubotConnectionwrite is that one byte is written

low-order bits of the argument b. The 24
high-order bits of b are ignored.

IBlaubotConnectionlen bytes from the specified byte array
starting at offset off to this output stream.
The general contract for write(b, off, len) is that
some of the bytes in the array b are written to the
output stream in order; element b[off] is the first
byte written and b[off+len-1] is the last byte written
by this operation.
The write method of OutputStream calls
the write method of one argument on each of the bytes to be
written out. Subclasses are encouraged to override this method and
provide a more efficient implementation.
If b is null, a
NullPointerException is thrown.
If off is negative, or len is negative, or
off+len is greater than the length of the array
b, then an IndexOutOfBoundsException is thrown.b - the data.off - the start offset in the data.len - the number of bytes to write.java.io.IOException - if an I/O error occurs. In particular,
