## Detailed Description

template<typename _PipelineHandler>
class libcamera::PipelineHandlerFactory< _PipelineHandler >

Registration of PipelineHandler classes and creation of instances.

Template Parameters

  _PipelineHandler | The pipeline handler class type for this factory

To facilitate discovery and instantiation of PipelineHandler classes, the PipelineHandlerFactory class implements auto-registration of pipeline handlers. Each PipelineHandler subclass shall register itself using the REGISTER_PIPELINE_HANDLER() macro, which will create a corresponding instance of a PipelineHandlerFactory and register it with the static list of factories.

## Constructor & Destructor Documentation

## ◆ PipelineHandlerFactory()

template<typename _PipelineHandler>

libcamera::PipelineHandlerFactory< _PipelineHandler >::PipelineHandlerFactory | ( | const char * | name | ) |
| inline

Construct a pipeline handler factory.

Parameters

  [in] | name | Name of the pipeline handler class

Creating an instance of the factory registers it with the global list of factories, accessible through the factories() function.

The factory name is used for debug purpose and shall be unique.

## Member Function Documentation

## ◆ createInstance()

template<typename _PipelineHandler>

std::unique_ptr< PipelineHandler > libcamera::PipelineHandlerFactory< _PipelineHandler >::createInstance | ( | CameraManager * | manager | ) | const
| inlineoverridevirtual

Create an instance of the PipelineHandler corresponding to the factory.

Parameters

  [in] | manager | The camera manager

Returns
  A unique pointer to a newly constructed instance of the PipelineHandler subclass corresponding to the factory
