Method Detail

setApplicationContext

public void setApplicationContext(org.springframework.context.ApplicationContext applicationContext)

Specified by:

setApplicationContext in interface org.springframework.context.ApplicationContextAware

Overrides:

setApplicationContext in class org.springframework.data.mapping.context.AbstractMappingContext<DatastorePersistentEntity<?>,DatastorePersistentProperty>

addDiscriminationClassConnection

public static void addDiscriminationClassConnection(Class parentClass,
                                                    Class subClass)

Registers in the DatastoreMappingContext that two classes are discriminated from the same Datastore Kind.

Parameters:

parentClass - the superclass.

subClass - the subclass.

getDiscriminationFamily

public static Set<Class> getDiscriminationFamily(Class clazz)

Get the set of other classes that share the same underlying Datastore Kind and that are subclasses of the given class.

Parameters:

clazz - the class to look up.

Returns:

a Set of other classes that share the same Kind that are subclasses. Will be null if this class is not discriminated from a set of other classes.

constructPersistentEntity

protected <T> DatastorePersistentEntityImpl<T> constructPersistentEntity(org.springframework.data.util.TypeInformation<T> typeInformation)

createPersistentEntity

protected <T> DatastorePersistentEntity<?> createPersistentEntity(org.springframework.data.util.TypeInformation<T> typeInformation)

Specified by:

createPersistentEntity in class org.springframework.data.mapping.context.AbstractMappingContext<DatastorePersistentEntity<?>,DatastorePersistentProperty>

createPersistentProperty

protected DatastorePersistentProperty createPersistentProperty(org.springframework.data.mapping.model.Property property,
                                                               DatastorePersistentEntity<?> owner,
                                                               org.springframework.data.mapping.model.SimpleTypeHolder simpleTypeHolder)

Specified by:

createPersistentProperty in class org.springframework.data.mapping.context.AbstractMappingContext<DatastorePersistentEntity<?>,DatastorePersistentProperty>

getDatastorePersistentEntity

@NonNull
public DatastorePersistentEntity<?> getDatastorePersistentEntity(Class<?> entityClass)

A non-null version of the MappingContext.getPersistentEntity(Class).

Parameters:

entityClass - the entity type.

Returns:

the DatastorePersistentEntity for the provided type.

Throws:

DatastoreDataException - if unable to retrieve a DatastorePersistentEntity for the provided type.
