Base class for camera sensor factories.
The CameraSensorFactoryBase class is the base of all specializations of the CameraSensorFactory class template. It implements the factory registration, maintains a registry of factories, and provides access to the registered factories.
◆ CameraSensorFactoryBase()
libcamera::CameraSensorFactoryBase::CameraSensorFactoryBase |
( |
const char * | name, |
|
|
int | priority ) |
Construct a camera sensor factory base.
- Parameters
-
[in] | name | The camera sensor factory name |
[in] | priority | Priority order for factory selection |
Creating an instance of the factory base registers it with the global list of factories, accessible through the factories() function.
◆ create()
Create an instance of the CameraSensor corresponding to a media entity.
- Parameters
-
[in] | entity | The media entity on the source end of the sensor |
When multiple factories match the same entity, this function selects the matching factory with the highest priority as specified to the REGISTER_CAMERA_SENSOR() macro at factory registration time. If multiple matching factories have the same highest priority value, which factory gets selected is undefined and may vary between runs.
- Returns
- A unique pointer to a new instance of the CameraSensor subclass matching the entity, or a null pointer if no such factory exists
◆ name()
const std::string & libcamera::CameraSensorFactoryBase::name |
( |
| ) |
const |
|
inline |
Retrieve the camera sensor factory name.
- Returns
- The name of the factory
◆ priority()
int libcamera::CameraSensorFactoryBase::priority |
( |
| ) |
const |
|
inline |
Retrieve the priority value for the factory.
- Returns
- The priority value for the factory
