EnablePluginFromThis Class Reference

EnablePluginFromThis is an optional base class which can be inherited by Plugin classes. When a Plugin class inherits it and that Plugin class is instantiated using the Loader class, its instance will be able to access the PluginPtr that manages its lifecycle.

PluginInstancePtrFromThis()

std::shared_ptr< void > PluginInstancePtrFromThis ( ) const

protected

This is an abstract shared_ptr to the Plugin instance. This shared_ptr will maintain a reference count on the shared library that provides the plugin so that the shared library does not get unloaded while this shared_ptr is still alive.

This function is meant for advanced use-cases, such as creating Factory plugins, so we keep it protected. Only use this if you know what you are doing.

Returns

shared_ptr to the Plugin instance.
