Examples of java.io.ByteArrayInputStream.reset()

java.io.ByteArrayInputStream.reset()
Reset this ByteArrayInputStream to the last marked location. This implementation resets the position to either the marked position, the start position supplied in the constructor or 0 if neither is provided.


            InputStream in = new ByteArrayInputStream(out.toByteArray());


            // should not cause SecurityException
            new ObjectInputStream(in);
            in.reset();


            // should not cause SecurityException
            new ObjectInputStream(in) {};
            in.reset();
