Member Function Documentation

template<typename TResourceType >
kanzi::ContentReference< TResourceType >::operator bool_type ( ) const
inline
template<typename TResourceType >
void kanzi::ContentReference< TResourceType >::setResource ( const ResourceID id)
inline

Sets the resource-ID of the content reference.

If the current reference is attached, acquires the resource.

template<typename TResourceType >
ResourceID kanzi::ContentReference< TResourceType >::getResourceId ( ) const
inline

Gets the resource ID the content reference is tracking.

Returns
Resource ID being tracked.
template<typename TResourceType >
void kanzi::ContentReference< TResourceType >::attachOverride ( )
inlineoverridevirtual

Attaches the content reference.

Acquires the resource referenced by the resource ID.

Note: The attach() is only called once.

Implements kanzi::AbstractResourceReference.

template<typename TResourceType >
void kanzi::ContentReference< TResourceType >::onResourceChangeOverride ( )
inlineoverridevirtual

This method is called when the resource referenced by the existing resource-ID is changed.

Acquires the new resource and executes the callback only if the the new resource is not the same as before.

Note: This method is only called on attached resource references.

Implements kanzi::AbstractResourceReference.

template<typename TResourceType >
void kanzi::ContentReference< TResourceType >::detachOverride ( )
inlineoverridevirtual

Detaches the content reference.

Resets the referenced resource.

Note: The detach() is only called once.

Implements kanzi::AbstractResourceReference.

template<typename TResourceType >
ResourceSharedPtr kanzi::ContentReference< TResourceType >::getResource ( )
inlineoverridevirtual
template<typename TResourceType >
ResourceTypePtr kanzi::ContentReference< TResourceType >::makeLocal ( )
inline

Clone reference to be an internal copy.

Default implementation clones nothing, and returns an empty shared pointer.

template<typename TResourceType >
ResourceTypePtr kanzi::ContentReference< TResourceType >::getUserResource ( ) const
inline

Access user resource.

Returns
User resource shared pointer.
template<typename TResourceType >
void kanzi::ContentReference< TResourceType >::resetUserResource ( )
inline

Clear user resource.

template<typename TResourceType >
void kanzi::ContentReference< TResourceType >::setUserResource ( ResourceTypePtr  userResource)
inline

Set user resource.

Parameters
userResourceNew user resource.
