Let met just keep this short and let the code speak for itself:
1 2 3 4 5 6 7 8 | // The next fields counts the number of time the decide method is called // // IMPORTANT: This field can be updated by multiple threads. It follows that // its values may *not* be incremented sequentially. However, we don't care // about the actual value of the field except that from time to time the // expression (invocationCounter++ & 0xF) == 0xF) should be true. private long invocationCounter = 0; |
Three letters apply here.
