Examples of com.peterhi.runtime.Buffer.reset()

com.peterhi.runtime.Buffer.reset()

Replaces the current read cursor with the previously recorded position assigned by a call to the {@link #mark()} method. Once this method iscalled, the read cursor will be rolled back to the previously recorded position, and the data that position will become available for read again. Please note that a call to {@link #reset()} will also reset the markedposition to {@link #EOF}. So after calling {@link #reset()} to rollback your read cursor, if you wish to be able to roll back to this position again, call {@link #mark()} immediately after for the markposition to be set to that position again. If there was no previously marked position, {@link #reset()} does nothing.

    
    // []011!00000 ==> EOF
    assertEquals(-1, withExistingData.read());
    
    // [011]00000 ! ==> Replace '!' with ']', and reset '!'
    withExistingData.reset();
    
    // [01]100000 !
    assertEquals(1, withExistingData.read());
    
    // [0]1100000 !
