Public functions

GetAvailableServableHandles

std::map< ServableId, ServableHandle< T > > GetAvailableServableHandles() const 

Returns a map of all the currently available servables of a particular type T.

The map is from the servable's id to its corresponding handle.

IMPORTANT: The caller should not hold onto the handles for a long time, because holding them will delay servable loading and unloading.

GetServableHandle

Status GetServableHandle(
  const ServableRequest & request,
  ServableHandle< T > *const handle
)

Returns a ServableHandle given a ServableRequest.

Returns error if no such Servable is available e.g. not yet loaded, has been quiesced/unloaded, etc. Callers may assume that an OK status indicates a non-null handle.

IMPORTANT: The caller should not hold onto the handles for a long time, because holding them will delay servable loading and unloading.

ListAvailableServableIds

virtual std::vector< ServableId > ListAvailableServableIds() const =0

Gets a list of all available servable ids, i.e.

each of these can be retrieved using GetServableHandle.
