Core::RefCounted Resources::SimpleResourceMapper


Detailed Description

Subclasses of ResourceMapper implement specific resource management strategies for one resource type (texture, mesh, etc...). Applications may implement their own specialized ResourceMappers if the provided standard mappers don't fit their needs. ResourceMappers are attached to the ResourceManager (one per resource type) and are called back by the resource server to perform resource creation and management. Resource clients never talk directly to ResourceMappers, instead they call the ResourceManager which in turn talks to the ResourceMappers.
