Detailed Description

template<class L>
class mitk::Mapper::LocalStorageHandler< L >

Templated class for management of LocalStorage implementations in Mappers.

The LocalStorageHandler is responsible for providing a LocalStorage to a concrete mitk::Mapper subclass. Each RenderWindow / mitk::BaseRenderer is assigned its own LocalStorage instance so that all contained ressources (actors, shaders, textures, ...) are provided individually per window.
