Package com.yahoo.log

Class LogMessageTimeComparator

java.lang.Object

com.yahoo.log.LogMessageTimeComparator

All Implemented Interfaces:

Serializable, Comparator<LogMessage>

public class LogMessageTimeComparator
extends Object
implements Comparator<LogMessage>, Serializable

Order LogMessage instances based on timestamp. The default ordering is ascending. This may be reversed by the constructor argument. Note: this comparator imposes orderings that are inconsistent with equals. This is due to only looking at the timestamp, so two different messages with the same timestamp would appear "equal" to this comparator.
