Method Detail

isLoadedWithoutReference

public javax.persistence.spi.LoadState isLoadedWithoutReference(Object paramObject,
                                                       String paramString)

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.

Specified by:

isLoadedWithoutReference in interface javax.persistence.spi.ProviderUtil

Parameters:

entity -

attributeName - name of attribute whose load status is to be determined

Returns:

load status of the attribute

isLoadedWithReference

public javax.persistence.spi.LoadState isLoadedWithReference(Object paramObject,
                                                    String paramString)

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 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 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. )

Specified by:

isLoadedWithReference in interface javax.persistence.spi.ProviderUtil

Parameters:

entity -

attributeName - name of attribute whose load status is to be determined

Returns:

load status of the attribute

isLoaded

public javax.persistence.spi.LoadState isLoaded(Object paramObject)

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.

Specified by:

isLoaded in interface javax.persistence.spi.ProviderUtil

Parameters:

entity - whose loaded status is to be determined

Returns:

load status of the entity
