Class LogPropertiesLoader

java.lang.Object

org.lsst.ccs.utilities.logging.LogPropertiesLoader

public class LogPropertiesLoader
extends Object

The role of this class is:

• to read the logging.properties and offer other codes (namely handlers) access to the properties described (a thing not permitted by the standard logManager)
• to be sure that the Handlers are lazily loaded (the standard LogManager may not be able to load the Handlers class due to ClassLoading problems)
• to delegate informations to the LogManager so it can behave properly (e.g. transmit logging properties, register Loggers) /UL>
