isLoaded(entity) - JPA ProviderUtil's method

Method
javax.persistence.spi.ProviderUtil
LoadState isLoaded(
  Object entity
)

If the provider determines that the entity has been provided by itself and that the state of all attributes for which FetchType.EAGER has been specified have been loaded, this method returns LoadState.LOADED.

If the provider determines that the entity has been provided by itself and that not all attributes with FetchType.EAGER have been loaded, this method returns LoadState.NOT_LOADED.

If the provider cannot determine if the entity has been provided by itself, this method returns LoadState.UNKNOWN.

The provider's implementation of this method must not obtain a reference to any attribute value, as this could trigger the loading of entity state if the entity has been provided by a different provider.

Parameters:
entity - whose loaded status is to be determined
Returns:
load status of the entity
