Class LogRecordComparator

java.lang.Object

alma.acs.logging.LogRecordComparator

All Implemented Interfaces:

java.util.Comparator<java.util.logging.LogRecord>

public class LogRecordComparator
extends java.lang.Object
implements java.util.Comparator<java.util.logging.LogRecord>

Comparator for LogRecord objects, which uses the log level, timestamp, and log sequence number for comparison.

From PriorityQueue: "The head of this queue is the least element with respect to the specified ordering.". Since we want the most important and oldest log messages first at the head, a higher level value and a smaller time value will result in a lower ordering position. Level takes precedence over time.
