Examples of java.io.ObjectInputStream.available()

java.io.ObjectInputStream.available()
Returns the number of bytes of primitive data available from the receiver. It should not be used at any arbitrary position; just when reading primitive data types (ints, chars, etc). @return the number of available primitive data bytes @throws IOException If any IO problem occurred when trying to compute the bytes available.

            ByteArrayInputStream bais = new ByteArrayInputStream
                (data.getData(), data.getOffset(), data.getSize());
