Events

Component based event handling

Declare methods in your components to handle events by prefixing the event name with onEmit_ & using unserscores (_) instead of periods (.). Example:

class RequestLogger extends \Lia\Compo {  
	public functon onEmit_Server_responseSent($responseOutput){  
	    file_put_contents(__DIR__.'/log.txt', 'Response sent at '.microtime(true), FILE_APPEND|LOCK_EX);  
	}  
}  

This function would be called for Server.responseSent event.

Create/Emit an event

Just call $lia->emit('Namespace.nameOfEvent', $param1, $param2, ...$etc)

Functional event handling

Call $lia->schedule('Namespace.nameOfEvent', $callable). Then $callable will be invoked whenever Namespace.nameOfEvent is emitted.

All Available Events

This may not be an exhaustive list & may not be kept up to date. You can search the liaison code base for ->emit( to find current event names. You can use func_get_args() to inspect the arguments passed to your event handler.

Server Events

• Server.willDisplayContent sends (\Lia\Obj\Response $response), which has two paramaters string $response->content and bool $response->useTheme. You can modify either of these
• Server.responseSent sends with no paramaters after all output has been sent to browser. Also see config lia.Server.bufferResponse
