Motivation
Currently, when
readPosition
==lastPosition‘next
, getNumberOfEntries will be entered. However, this is meaningless and may affect performance.For example, readPosition=3:0, lastPosition=3:-1, will enter the getNumberOfEntries method
Modifications
When
readPosition
is greater thanlastPosition
, return 0 directly.Documentation
