nvinfer1::IPluginRegistry Class Referenceabstract

Single registration point for all plugins in an application. It is used to find plugin implementations during engine deserialization. Internally, the plugin registry is considered to be a singleton so all plugins in an application are part of the same global registry. Note that the plugin registry is only supported for plugins of type IPluginV2 and should also have a corresponding IPluginCreator implementation. More...

Detailed Description

Single registration point for all plugins in an application. It is used to find plugin implementations during engine deserialization. Internally, the plugin registry is considered to be a singleton so all plugins in an application are part of the same global registry. Note that the plugin registry is only supported for plugins of type IPluginV2 and should also have a corresponding IPluginCreator implementation.

Warning
Do not inherit from this class, as doing so will break forward-compatibility of the API and ABI.
In the automotive safety context, be sure to call IPluginRegistry::setErrorRecorder() to register an error recorder with the registry before using other methods in the registry.

Member Function Documentation

◆ deregisterCreator()

virtual bool nvinfer1::IPluginRegistry::deregisterCreator ( IPluginCreator const &  creator)
pure virtualnoexcept

Deregister a previously registered plugin creator.

Since there may be a desire to limit the number of plugins, this function provides a mechanism for removing plugin creators registered in TensorRT. The plugin creator that is specified by creator is removed from TensorRT and no longer tracked.

Returns
True if the plugin creator was deregistered, false if it was not found in the registry or otherwise could not be deregistered.

◆ getErrorRecorder()

virtual IErrorRecorder* nvinfer1::IPluginRegistry::getErrorRecorder ( ) const
pure virtualnoexcept

Set the ErrorRecorder assigned to this interface.

Retrieves the assigned error recorder object for the given class. A default error recorder does not exist, so a nullptr will be returned if setErrorRecorder has not been called, or an ErrorRecorder has not been inherited.

Returns
A pointer to the IErrorRecorder object that has been registered.

◆ setErrorRecorder()

virtual void nvinfer1::IPluginRegistry::setErrorRecorder ( IErrorRecorder *const  recorder)
pure virtualnoexcept

Set the ErrorRecorder for this interface.

Assigns the ErrorRecorder to this interface. The ErrorRecorder will track all errors during execution. This function will call incRefCount of the registered ErrorRecorder at least once. Setting recorder to nullptr unregisters the recorder with the interface, resulting in a call to decRefCount if a recorder has been registered.

Parameters
recorderThe error recorder to register with this interface.
