isLoadedWithoutReference(entity, attributeName) - JPA ProviderUtil's method

Method
javax.persistence.spi.ProviderUtil
LoadState isLoadedWithoutReference(
  Object entity,
  String attributeName
)

If the provider determines that the entity has been provided by itself and that the state of the specified attribute has been loaded, this method returns 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.

Parameters:
entity - entity instance
attributeName - name of attribute whose load status is to be determined
Returns:
load status of the attribute
