Field Detail CATEGORY_SEPARATOR final public static char CATEGORY_SEPARATOR(Code) Separator character use to separate different categories Constructor Detail Logger Logger(ErrorHandler errorHandler, LoggerListener loggerListener, String category, LogTarget[] logTargets, Logger parent)(Code) Protected constructor for use inside the logging toolkit. You should not be using this constructor directly. Parameters:   errorHandler - the ErrorHandler logger uses to log errors Parameters:   category - the fully qualified name of category Parameters:   logTargets - the LogTargets associated with logger Parameters:   parent - the parent logger (used for inheriting from) Method Detail debug final public void debug(String message, Throwable throwable)(Code) Log a debug priority event. Parameters:   message - the message Parameters:   throwable - the throwable debug final public void debug(String message)(Code) Log a debug priority event. Parameters:   message - the message error final public void error(String message, Throwable throwable)(Code) Log a error priority event. Parameters:   message - the message Parameters:   throwable - the throwable error final public void error(String message)(Code) Log a error priority event. Parameters:   message - the message fatalError final public void fatalError(String message, Throwable throwable)(Code) Log a fatalError priority event. Parameters:   message - the message Parameters:   throwable - the throwable fatalError final public void fatalError(String message)(Code) Log a fatalError priority event. Parameters:   message - the message getCategory final public String getCategory()(Code) Retrieve category associated with logger. the Category getChildLogger public synchronized Logger getChildLogger(String subCategory) throws IllegalArgumentException(Code) Create a new child logger. The category of child logger is [current-category].subcategory Parameters:   subCategory - the subcategory of this logger the new logger exception:   IllegalArgumentException - if subCategory has an empty element name getChildren public synchronized Logger[] getChildren()(Code) Get all the child Loggers of current logger. the child loggers getLogTargets public LogTarget[] getLogTargets()(Code) Get a copy of log targets for this logger. the child loggers getPriority final public Priority getPriority()(Code) Retrieve priority associated with Logger. the loggers priority info final public void info(String message, Throwable throwable)(Code) Log a info priority event. Parameters:   message - the message Parameters:   throwable - the throwable info final public void info(String message)(Code) Log a info priority event. Parameters:   message - the message isDebugEnabled final public boolean isDebugEnabled()(Code) Determine if messages of priority DEBUG will be logged. true if DEBUG messages will be logged isErrorEnabled final public boolean isErrorEnabled()(Code) Determine if messages of priority ERROR will be logged. true if ERROR messages will be logged isFatalErrorEnabled final public boolean isFatalErrorEnabled()(Code) Determine if messages of priority FATAL_ERROR will be logged. true if FATAL_ERROR messages will be logged isInfoEnabled final public boolean isInfoEnabled()(Code) Determine if messages of priority INFO will be logged. true if INFO messages will be logged isPriorityEnabled final public boolean isPriorityEnabled(Priority priority)(Code) Determine if messages of priority  will be logged. Parameters:   priority - the priority true if messages will be logged isWarnEnabled final public boolean isWarnEnabled()(Code) Determine if messages of priority WARN will be logged. true if WARN messages will be logged log final public void log(Priority priority, String message, Throwable throwable)(Code) Log a event at specific priority with a certain message and throwable. Parameters:   priority - the priority Parameters:   message - the message Parameters:   throwable - the throwable log final public void log(Priority priority, String message)(Code) Log a event at specific priority with a certain message. Parameters:   priority - the priority Parameters:   message - the message setAdditivity final public void setAdditivity(boolean additivity)(Code) Make this logger additive. I.e. Send all log events to parent loggers LogTargets regardless of whether or not the LogTargets have been overidden. This is derived from Log4js notion of Additivity. Parameters:   additivity - true to make logger additive, false otherwise setLogTargets public synchronized void setLogTargets(LogTarget[] logTargets)(Code) Set the log targets for this logger. Parameters:   logTargets - the Log Targets setPriority public synchronized void setPriority(Priority priority)(Code) Set the priority for this logger. Parameters:   priority - the priority unsetLogTargets public synchronized void unsetLogTargets()(Code) Unset the logtargets for this logger. This logger (and thus all child loggers who don't specify logtargets) will inherit from the parents LogTargets. unsetLogTargets public synchronized void unsetLogTargets(boolean recursive)(Code) Unset the logtargets for this logger and all child loggers if recursive is set. The loggers unset (and all child loggers who don't specify logtargets) will inherit from the parents LogTargets. Parameters:   recursive - the recursion policy unsetPriority public synchronized void unsetPriority()(Code) Unset the priority of Logger. (Thus it will use it's parent's priority or DEBUG if no parent. unsetPriority public synchronized void unsetPriority(boolean recursive)(Code) Unset the priority of Logger. (Thus it will use it's parent's priority or DEBUG if no parent. If recursive is true unset priorities of all child loggers. Parameters:   recursive - true to unset priority of all child loggers warn final public void warn(String message, Throwable throwable)(Code) Log a warn priority event. Parameters:   message - the message Parameters:   throwable - the throwable warn final public void warn(String message)(Code) Log a warn priority event. Parameters:   message - the message Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
