Class CachedClock
java.lang.Object
org.apache.logging.log4j.core.util.CachedClock
- All Implemented Interfaces:
Clock
Implementation of the
Clock
interface that tracks the time in a
private long field that is updated by a background thread once every
millisecond. Timers on most platforms do not have millisecond granularity, so
the returned value may "jump" every 10 or 16 milliseconds. To reduce this
problem, this class also updates the internal time value every 1024 calls to
currentTimeMillis()
.-
