LoadState.LOADED
. If the provider determines that the entity has been provided by itself and that either entity attributes with FetchType.EAGER
have not been loaded or that the state of the specified attribute has not been loaded, this methods returns LoadState.NOT_LOADED
. If a provider cannot determine the load state, this method returns LoadState.UNKNOWN
. The provider's implementation of this method must not obtain a reference to an attribute value, as this could trigger the loading of entity state if the entity has been provided by a different provider.isLoadedWithoutReference

. If a provider determines that the entity has been provided by itself and that either the entity attributes with FetchType.EAGER
have not been loaded or that the state of the specified attribute has not been loaded, this method returns return LoadState.NOT_LOADED
. If the provider cannot determine the load state, this method returns LoadState.UNKNOWN
. The provider's implementation of this method is permitted to obtain a reference to the attribute value. (This access is safe because providers which might trigger the loading of the attribute state will have already been determined by isLoadedWithoutReference
