Class Overview

Global logging facility used by JEB. This class offers methods to create per-class loggers. Upon initialization, a JEB client should add destination streams and buffers. The official RCP client implementation provided with JEB registers stdout as well as the UI console window as destinations.

This class is thread-safe. However, ILogger instances returned by getLogger() are not thread-safe.

How to use: 

 import com.pnfsoftware.jeb.util.logging.ILogger;
 import com.pnfsoftware.jeb.util.loggingg.GlobalLog;
 
 class Xyz {
     private static final ILogger logger = GlobalLog.getLogger(Xyz.class);
     ...
 }

Public Methods

public static synchronized void addDestinationBuffer (List<String> buffer)

Add a destination buffer to the list of log message recipients. The list implementation must be thread-safe: it should be an object returned by Collections.synchronizedList()

Parameters
buffer the thread-safe buffer

public static synchronized void addDestinationStream (PrintStream out)

Add a destination stream to the list of log message recipients.

Parameters
out a destination stream

public static synchronized void addGlobalFilter (String pattern, int requiredLevel)

public static synchronized void clearGlobalFilters ()

public static synchronized List<List<String>> getDestinationBuffers ()

Get the list of destination buffers.

Returns
  • the list of destination buffers

public static synchronized List<PrintStream> getDestinationStreams ()

Get the list of destination streams.

Returns
  • the list of destination streams

public static synchronized int getEnabledLevel ()

Get the default logging level.

Returns
  • the default logging level

public static synchronized ILogger getInternalLogger (Class<?> clazz)

Create or retrieve an internal logger. INTERNAL USAGE ONLY.

public static synchronized ILogger getLogger (String name, int level)

Create or retrieve a named logger.

Parameters
name logger name
level the cut-off level
Returns
  • the logger

public static synchronized ILogger getLogger (Class<?> clazz, int level)

Create or retrieve a logger attached to and named after a given class.

Parameters
clazz class reference
level the cut-off level
Returns
  • the logger

public static synchronized ILogger getLogger ()

Create or retrieve the anonymous logger. If created, the logging level is set to the default global logging level.

Returns
  • the anonymous logger

public static synchronized ILogger getLogger (Class<?> clazz)

Create or retrieve a logger attached to and named after a given class. If created, the logging level is set to the default global logging level.

Parameters
clazz class reference
Returns
  • the logger

public static synchronized boolean isGloballyDisabled (ILogger logger)

public static void logDebugStacktrace (ILogger logger, Throwable t)

Utility method used to log a stack trace at the debug level.

public static synchronized void removeDestinationBuffer (List<String> buffer)

Remove a destination buffer.

Parameters
buffer the destination buffer

public static synchronized void removeDestinationStream (PrintStream out)

Remove a destination stream.

Parameters
out the destination stream

public static synchronized void removeGlobalFilter (String pattern)

public static synchronized void setEnabledLevel (int level, boolean updateExistingLoggers)

public static synchronized void setEnabledLevel (int level)

Set the default logging level

Parameters
level the default logging level
