Member Function Documentation

◆ operator bool_type()

template<typename TResourceType >

kanzi::ContentReference< TResourceType >::operator bool_type ( ) const

inline

◆ setResource()

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.

◆ getResourceId()

template<typename TResourceType >

ResourceID kanzi::ContentReference< TResourceType >::getResourceId ( ) const

inline

Gets the resource ID the content reference is tracking.

Returns: Resource ID being tracked.

◆ attachOverride()

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.

◆ onResourceChangeOverride()

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.

◆ detachOverride()

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.

◆ getResource()

template<typename TResourceType >

ResourceSharedPtr kanzi::ContentReference< TResourceType >::getResource ( )

inlineoverridevirtual

Implements kanzi::AbstractResourceReference.

◆ makeLocal()

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.

◆ getUserResource()

template<typename TResourceType >

ResourceTypePtr kanzi::ContentReference< TResourceType >::getUserResource ( ) const

inline

Access user resource.

Returns: User resource shared pointer.

◆ resetUserResource()

template<typename TResourceType >

void kanzi::ContentReference< TResourceType >::resetUserResource ( )

inline

Clear user resource.

◆ setUserResource()

template<typename TResourceType >

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

inline

Set user resource.

Parameters

userResource New user resource.

◆ setCallback()

template<typename TResourceType >

void kanzi::ContentReference< TResourceType >::setCallback ( CallbackType callback )

inline

◆ get()

template<typename TResourceType >

ResourceTypePtr kanzi::ContentReference< TResourceType >::get ( ) const

inline

◆ operator->()

inline

◆ operator*()

template<typename TResourceType >

TResourceType & kanzi::ContentReference< TResourceType >::operator* ( ) const
