Constructor Detail

AsyncHandler

public AsyncHandler(int queueLength,
                    ThreadFactory threadFactory)

Construct a new instance.

Parameters:

queueLength - the queue length

threadFactory - the thread factory to use to construct the handler thread

AsyncHandler

public AsyncHandler(ThreadFactory threadFactory)

Construct a new instance.

Parameters:

threadFactory - the thread factory to use to construct the handler thread

AsyncHandler

public AsyncHandler(int queueLength)

Construct a new instance.

Parameters:

queueLength - the queue length

AsyncHandler

public AsyncHandler()

Construct a new instance.

Method Detail

getQueueLength

public int getQueueLength()

The full size of the queue.

Returns:

the full size of the queue.

getOverflowAction

public AsyncHandler.OverflowAction getOverflowAction()

Get the overflow action.

Returns:

the overflow action

setOverflowAction

public void setOverflowAction(AsyncHandler.OverflowAction overflowAction)

Set the overflow action.

Parameters:

overflowAction - the overflow action

doPublish

protected void doPublish(ExtLogRecord record)

Do the actual work of publication; the record will have been filtered already. The default implementation does nothing except to flush if the autoFlush property is set to true; if this behavior is to be preserved in a subclass then this method should be called after the record is physically written.

Overrides:

doPublish in class ExtHandler

Parameters:

record - the log record to publish

close

public void close()
           throws SecurityException

Close all child handlers.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Overrides:

close in class ExtHandler

Throws:

SecurityException
