| Method Summary | |
| public synchronized void | close()
Shutdown target. | | abstract protected void | doProcessEvent(LogEvent event)
Process a log event, via formatting and outputting it. | | final protected void | error(String message, Throwable throwable)
Helper method to write error messages to error handler. | | final protected ErrorHandler | getErrorHandler()
Helper method to retrieve ErrorHandler for subclasses. | | protected synchronized boolean | isOpen()
Return the open state of the target. | | protected synchronized void | open()
Startup log session. | | public synchronized void | processEvent(LogEvent event)
Process a log event, via formatting and outputting it. | | public synchronized void | setErrorHandler(ErrorHandler errorHandler)
Provide component with ErrorHandler. |
| AbstractTarget | | public AbstractTarget()(Code) | | AbstractTarget constructor.
|
| AbstractTarget | | public AbstractTarget(ErrorHandler errorHandler)(Code) | | AbstractTarget constructor.
Parameters:
errorHandler - the error handler |
| close | | public synchronized void close()(Code) | | Shutdown target.
Attempting to write to target after close() will cause errors to be logged.
|
| doProcessEvent | | abstract protected void doProcessEvent(LogEvent event) throws Exception(Code) | | Process a log event, via formatting and outputting it.
This should be overidden by subclasses.
Parameters:
event - the log event
exception:
Exception - if an event processing error occurs |
| error | | final protected void error(String message, Throwable throwable)(Code) | | Helper method to write error messages to error handler.
Parameters:
message - the error message
Parameters:
throwable - the exception if any |
| getErrorHandler | | final protected ErrorHandler getErrorHandler()(Code) | | Helper method to retrieve ErrorHandler for subclasses.
the ErrorHandler |
| isOpen | | protected synchronized boolean isOpen()(Code) | | Return the open state of the target.
TRUE if the target is open else FALSE |
| open | | protected synchronized void open()(Code) | | Startup log session.
|
| processEvent | | public synchronized void processEvent(LogEvent event)(Code) | | Process a log event, via formatting and outputting it.
Parameters:
event - the log event |
| setErrorHandler | | public synchronized void setErrorHandler(ErrorHandler errorHandler)(Code) | | Provide component with ErrorHandler.
Parameters:
errorHandler - the errorHandler |
