Examples of java.io.DataInputStream.available()

java.io.DataInputStream.available()
Returns the number of bytes that can be read from this input stream without blocking.
This method simply performs in.available() and returns the result. @return the number of bytes that can be read from the input streamwithout blocking. @exception IOException if an I/O error occurs.

                int len = in.readInt();
                byte[] tuple = new byte[len];
                in.read(tuple);
                tuples.add(tuple);
            }
            if(in.available() > 0) {
                throw new IllegalStateException(in.available() + " bytes left");
            }
            this.totalDataLen = v.getLength();
            this.loaded = true;
        }
