DisplayService Class Reference

#include "stage/display-service.hpp"

Description

Actual implementation of the DisplayService.

Creating an instance of this class automatically registers the interface lumieraorg_Display with the Lumiera Interface/Plugin system and creates a forwarding proxy within the application core to route calls through this interface.

In addition to the Display interface, this class implements an additional service for the GUI, allowing actually to set up display slots, which then can be handed out to client code in the course of the play process for outputting frames.

allocate()

void allocate	(	LumieraDisplaySlot	handle,
		bool	doAllocate
	)

prepare and the given slot for output

Parameters

doAllocate

allocate when true, else release it

Exceptions

lumiera::error::Logic

when already in use

Definition at line 187 of file display-service.cpp.

resolve()

DisplayerSlot & resolve

(

LumieraDisplaySlot

handle

)

resolve the given display slot handle to yield a ref to an actual implementation object.

In order to be resolvable, the DisplayerSlot needs to be locked (=allocated) for output use.
