public interface MappingContext<E extends PersistentEntity<?,P>,P extends PersistentProperty<P>>
This interface defines the overall context including all known PersistentEntity instances and methods to obtain instances on demand. it is used internally to establish associations between entities and also at runtime to obtain entities by name.
| Method Summary | |
|---|---|
Collection<E> |
getPersistentEntities()
Returns all PersistentEntitys held in the context. |
E |
getPersistentEntity(Class<?> type)
Returns a PersistentEntity for the given Class. |
E |
getPersistentEntity(P persistentProperty)
Returns the PersistentEntity mapped by the given PersistentProperty. |
E |
getPersistentEntity(TypeInformation<?> type)
Returns a PersistentEntity for the given TypeInformation. |
PersistentPropertyPath<P> |
getPersistentPropertyPath(PropertyPath propertyPath)
Returns all PersistentPropertys for the given path expression based on the given PropertyPath. |
| Method Detail |
|---|
Collection<E> getPersistentEntities()
PersistentEntitys held in the context.
E getPersistentEntity(Class<?> type)
PersistentEntity for the given Class. Will return null for types that are
considered simple ones.
type - must not be null.
SimpleTypeHolder.isSimpleType(Class)E getPersistentEntity(TypeInformation<?> type)
PersistentEntity for the given TypeInformation. Will return null for types
that are considered simple ones.
type - must not be null.
SimpleTypeHolder.isSimpleType(Class)E getPersistentEntity(P persistentProperty)
PersistentEntity mapped by the given PersistentProperty.
persistentProperty -
PersistentEntity mapped by the given PersistentProperty or null if no
PersistentEntity exists for it or the PersistentProperty does not refer to an entity (the
type of the property is considered simple see
SimpleTypeHolder.isSimpleType(Class)).PersistentPropertyPath<P> getPersistentPropertyPath(PropertyPath propertyPath)
PersistentPropertys for the given path expression based on the given PropertyPath.
