de.aristaflow.adept2.util.logging.WrappingLogger

Direct Known Subclasses:

DebugLogger, NameWrappingLogger

public class WrappingLogger
extends Logger

This logger wraps a normal logger and handles setting the log level appropriately. This allows for easy wrapping and extending a logger.
This logger may have a different name than the wrapped logger.

Logging is only forwarded to the wrapped logger in case this logs for the level of the current record. Otherwise logging is done by this logger.

Field Details

innerLogger

protected final Logger innerLogger

The wrapped logger.

Constructor Details

WrappingLogger

protected WrappingLogger(Logger innerLogger)

Creates a new logger wrapping the designated one. The created logger will have the same name as the wrapped logger.

Parameters:

innerLogger - The logger to which all requests will be forwarded.

WrappingLogger

protected WrappingLogger(String name,
 Logger innerLogger)

Creates a new logger wrapping the designated one and having the designated name.

Parameters:

innerLogger - The logger to which all requests will be forwarded.

name - The name of the logger (this). This name is used in log records.

Method Details

getResourceBundle

public ResourceBundle getResourceBundle()

Overrides:

getResourceBundle in class Logger

getResourceBundleName

public String getResourceBundleName()

Overrides:

getResourceBundleName in class Logger

setFilter

public void setFilter(Filter newFilter)
               throws SecurityException

Overrides:

setFilter in class Logger

Throws:

SecurityException

getFilter

public Filter getFilter()

Overrides:

getFilter in class Logger

setLevel

public void setLevel(Level newLevel)
              throws SecurityException

Overrides:

setLevel in class Logger

Throws:

SecurityException

setLevel

protected void setLevel(Level newLevel,
 boolean propagate)

Sets the level of this logger to the designated one. The designated level may be propagated to the wrapped logger. This propagation may change the effective level (due to the level of parent loggers). In this case the level of this logger will be set appropriately to the effective level.

Parameters:

newLevel - The level to set in this logger.

propagate - Whether the designated level should be propagated to the wrapped logger.

getLevel

public Level getLevel()

Overrides:

getLevel in class Logger

isLoggable

public boolean isLoggable(Level level)

Since this method delegates to the inner logger, it usually has to be overridden in case (a subclass of) this logger sets the level without propagating it to the wrapped logger.

Overrides:

isLoggable in class Logger

getName

public String getName()

Overrides:

getName in class Logger

addHandler

public void addHandler(Handler handler)
                throws SecurityException

Overrides:

addHandler in class Logger

Throws:

SecurityException

removeHandler

public void removeHandler(Handler handler)
                   throws SecurityException

Overrides:

removeHandler in class Logger

Throws:

SecurityException

getHandlers

public Handler[] getHandlers()

Overrides:

getHandlers in class Logger

setUseParentHandlers

public void setUseParentHandlers(boolean useParentHandlers)

Overrides:

setUseParentHandlers in class Logger

getUseParentHandlers

public boolean getUseParentHandlers()

Overrides:

getUseParentHandlers in class Logger

getParent

public Logger getParent()

Overrides:

getParent in class Logger

setParent

public void setParent(Logger parent)

Overrides:

setParent in class Logger

log

public void log(LogRecord record)

Logs the designated record by the wrapped logger in case the wrapped logger logs the corresponding level. Otherwise the record is logged by the wrapping logger.

Overrides:

log in class Logger

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Calls equals(Object) of the inner logger. However, the designated object will be unwrapped if it is also a WrappingLogger.

Overrides:

equals in class Object
