Method Detail

setApplicationContext

public void setApplicationContext(org.springframework.context.ApplicationContext applicationContext)
                           throws org.springframework.beans.BeansException

Specified by:

setApplicationContext in interface org.springframework.context.ApplicationContextAware

Overrides:

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

Throws:

org.springframework.beans.BeansException

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 aClass)

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

Parameters:

aClass - 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.
