org.glassfish.main.jul.GlassFishLogger

public class GlassFishLogger
extends Logger

Custom Logger, integrated with GlassFishLogManager, so if the log manager is reconfiguring, the logger reacts on states of the log manager. Then log records can be redirected to a startup queue (if the logging is not configured or is reconfiguring) or the calling thread is blocked until the log manager finishes flushing of the queue) or processed as usually.

getHandler

public <T extends Handler> T getHandler(Class<T> type)

Searches for a handler of some type and returns the first found. Note: the comparison uses Class.equals, so it respects classloaders.

Type Parameters:

T - Handler type.

Parameters:

type -

Returns:

found handler or null.

getHandlers

Uses Logger.getHandlers() and filters output to return only handlers implementing the class from a parameter.

Parameters:

type - type used for filtering; can be also an interface

Returns:

list of found handlers (may be empty but never null)

isLoggable

public boolean isLoggable(Level level)

This method is overriden because it is called from clients to check if it makes sense to do some expensive preparation and call of any log method, but we don't know it yet, so we accept everything to queue (it should not be so many records).

Overrides:

isLoggable in class Logger

isProcessible

protected boolean isProcessible(Level level,
 GlassFishLoggingStatus status)

Parameters:

level - a message logging level

status - the state of the logging system

Returns:

true if the given message level is currently being logged or if we don't know yet.

isLoggableLevel

protected boolean isLoggableLevel(Level level)

Parameters:

level - - log record level

Returns:

true if level has higher importance than level set to this logger (or parent)
