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.

      int available1 = 0;
      int available2 = 0;
      Object obj1 = null;
      Object obj2 = null;
      ObjectInputStream ois = new ObjectInputStream(loadStream());
      available1 = ois.available();
      obj1 = ois.readObject();
      available2 = ois.available();
      obj2 = ois.readObject();


      assertEquals("available returned incorrect value", 0, available1);
