Method Detail

getOwner

PersistentEntity<?,P> getOwner()

getName

String getName()

The name of the property

Returns:

The property name

getType

Class<?> getType()

The type of the property

Returns:

The property type

getTypeInformation

TypeInformation<?> getTypeInformation()

getPersistentEntityType

Iterable<? extends TypeInformation<?>> getPersistentEntityType()

Returns the TypeInformation if the property references a PersistentEntity. Will return null in case it refers to a simple type. Will return Collection's component type or the Map's value type transparently.

Returns:

getPropertyDescriptor

PropertyDescriptor getPropertyDescriptor()

Returns the PropertyDescriptor backing the PersistentProperty.

Returns:

getField

Field getField()

getSpelExpression

String getSpelExpression()

getAssociation

Association<P> getAssociation()

isEntity

boolean isEntity()

Returns whether the type of the PersistentProperty is actually to be regarded as PersistentEntity in turn.

Returns:

isIdProperty

boolean isIdProperty()

Returns whether the property is a potential identifier property of the owning PersistentEntity. This method is mainly used by PersistentEntity implementation to discover id property candidates on PersistentEntity creation you should rather call PersistentEntity.isIdProperty(PersistentProperty) to determine whether the current property is the id property of that PersistentEntity under consideration.

Returns:

isCollectionLike

boolean isCollectionLike()

Returns whether the property is a Collection, Iterable or an array.

Returns:

isMap

boolean isMap()

Returns whether the property is a Map.

Returns:

isArray

boolean isArray()

Returns whether the property is an array.

Returns:

isTransient

boolean isTransient()

Returns whether the property is transient.

Returns:

shallBePersisted

boolean shallBePersisted()

isAssociation

boolean isAssociation()

Returns whether the property is an Association.

Returns:

getComponentType

Class<?> getComponentType()

Returns the component type of the type if it is a Collection. Will return the type of the key if the property is a Map.

Returns:

the component type, the map's key type or null if neither Collection nor Map.

getRawType

Class<?> getRawType()

Returns the raw type as it's pulled from from the reflected property.

Returns:

the raw type of the property.

getMapValueType

Class<?> getMapValueType()

Returns the type of the values if the property is a Map.

Returns:

the map's value type or null if no Map
