Detailed Description

Buffers all records until closing the handler and then pass them as batch.

This is useful for a MailHandler to send only one mail per request instead of sending one per log message.

Constructor & Destructor Documentation

__construct()

Monolog\Handler\BufferHandler::__construct	(	HandlerInterface	$handler,
			$bufferLimit = 0,
			$level = Logger::DEBUG,
			$bubble = true,
			$flushOnOverflow = false
	)

Parameters

HandlerInterface	$handler	Handler.
int	$bufferLimit	How many entries should be buffered at most, beyond that the oldest items are removed from the buffer.
int	$level	The minimum logging level at which this handler will be triggered
Boolean	$bubble	Whether the messages that are handled can bubble up the stack or not
Boolean	$flushOnOverflow	If true, the buffer is flushed when the max size has been reached, by default oldest entries are discarded

        // suppress the parent behavior since we already have register_shutdown_function()
        // to call close(), and the reference contained there will prevent this from being
        // GC'd until the end of the request
