public CorePersistentAttributesLoadChecker()

Method Details

isLoaded

public boolean isLoaded(Object entity,
 String property)

Description copied from interface: PersistentAttributesLoadChecker

Checks whether the property is loaded from the data store. This may trigger fetching of the property if its state cannot be determined using standard JPA mechanisms.

Specified by:

isLoaded in interface PersistentAttributesLoadChecker

See Also:

• EntityStates.isLoaded(Object, String)

isLoadedInternal

public EntityStates.PropertyLoadedState isLoadedInternal(Object entity,
 String property,
 boolean safe)

Checks whether the property of the entity is loaded.

Parameters:

safe - determines the behavior when the loaded state cannot be determined using standard JPA mechanisms: if true, UNKNOWN is returned; if false, the getter is invoked, which may trigger lazy loading

isLoadedSafe

public EntityStates.PropertyLoadedState isLoadedSafe(Object entity,
 String property)

Description copied from interface: PersistentAttributesLoadChecker

Checks whether the property is loaded from the data store without risking fetching it.

Specified by:

isLoadedSafe in interface PersistentAttributesLoadChecker

See Also:

• EntityStates.isLoaded(Object, String)

isLoadedCommonCheck

protected EntityStates.PropertyLoadedState isLoadedCommonCheck(Object entity,
 String property)

isLoadedByFetchGroup

protected EntityStates.PropertyLoadedState isLoadedByFetchGroup(Object entity,
 String property)

isLoadedSpecificCheck

protected EntityStates.PropertyLoadedState isLoadedSpecificCheck(Object entity,
 String property,
 MetaClass metaClass,
 MetaProperty metaProperty,
 boolean safe)

Checks whether the property of the entity is loaded using store-specific mechanisms.

Parameters:

safe - determines the behavior when the loaded state cannot be determined using standard mechanisms: if true, UNKNOWN is returned; if false, the getter is invoked, which may trigger lazy loading

checkIsLoadedWithGetter

protected EntityStates.PropertyLoadedState checkIsLoadedWithGetter(Object entity,
 String property)
