Detailed Description

template<class T>
class xy::BaseResource< T >

Abstract base class for resource management.

The templated base class provides resource management for types given by derived classes. Resource management makes sure only a single instance of each resource, such as a texture or shader is loaded at a time.

errorHandle()

template<class T >

virtual std::unique_ptr<T> xy::BaseResource< T >::errorHandle ( )

protectedpure virtual

Function for handling resource acquisition errors.

Concrete resource manager types must implement this to provide a fallback instance of the resource type, should loading of the requested resource fail for some reason.

get()

template<class T >

T& xy::BaseResource< T >::get ( const std::string &  path = "default" )

inline

Attempts to load a resource from disk at the given path.

If the resource is not found or fails to load the resource manager supplies a fallback resource, as defined by the concrete implementation of the resource manager.
