Class LogItemDictionary

java.lang.Object

org.safs.logging.LogItemDictionary

public class LogItemDictionary
extends java.lang.Object

This is a helper class for log facilities to store their LogItems. This class maps log type indentifier (LOGMODE constant defined by AbstractLogFacility) to a LogItem of that type. This implies that only one LogItem of a particular type can be stored in a LogItemDictionary, which is always the case for log facilities.
