                                  PersistentEntity<?,P> owner,
                                  SimpleTypeHolder simpleTypeHolder)

Method Detail

createAssociation

protected abstract Association<P> createAssociation()

getName

public String getName()

Description copied from interface: PersistentProperty

The name of the property

Specified by:

getName in interface PersistentProperty<P extends PersistentProperty<P>>

Returns:

The property name

getType

public Class<?> getType()

Description copied from interface: PersistentProperty

The type of the property

Specified by:

getType in interface PersistentProperty<P extends PersistentProperty<P>>

Returns:

The property type

getRawType

public Class<?> getRawType()

Description copied from interface: PersistentProperty

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

Specified by:

getRawType in interface PersistentProperty<P extends PersistentProperty<P>>

Returns:

the raw type of the property.

getTypeInformation

public TypeInformation<?> getTypeInformation()

Description copied from interface: PersistentProperty

Returns the TypeInformation of the property.

Specified by:

getTypeInformation in interface PersistentProperty<P extends PersistentProperty<P>>

Returns:

getPersistentEntityType

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

Description copied from interface: PersistentProperty

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.

Specified by:

getPersistentEntityType in interface PersistentProperty<P extends PersistentProperty<P>>

Returns:

getGetter

public Optional<Method> getGetter()

Description copied from interface: PersistentProperty

Returns the getter method to access the property value if available. Might return null in case there is no getter method with a return type assignable to the actual property's type.

Specified by:

getGetter in interface PersistentProperty<P extends PersistentProperty<P>>

Returns:

the getter method to access the property value if available, otherwise null.

getSetter

public Optional<Method> getSetter()

Description copied from interface: PersistentProperty

Returns the setter method to set a property value. Might return null in case there is no setter available.

Specified by:

getSetter in interface PersistentProperty<P extends PersistentProperty<P>>

Returns:

the setter method to set a property value if available, otherwise null.

getField

public Optional<Field> getField()

Specified by:

getField in interface PersistentProperty<P extends PersistentProperty<P>>

getSpelExpression

public Optional<String> getSpelExpression()

Specified by:

getSpelExpression in interface PersistentProperty<P extends PersistentProperty<P>>

isTransient

public boolean isTransient()

Description copied from interface: PersistentProperty

Returns whether the property is transient.

Specified by:

isTransient in interface PersistentProperty<P extends PersistentProperty<P>>

Returns:

isWritable

public boolean isWritable()

Description copied from interface: PersistentProperty

Returns whether the current property is writable, i.e. if the value held for it shall be written to the data store.

Specified by:

isWritable in interface PersistentProperty<P extends PersistentProperty<P>>

Returns:

isAssociation

public boolean isAssociation()

Description copied from interface: PersistentProperty

Returns whether the property is an Association.

Specified by:

isAssociation in interface PersistentProperty<P extends PersistentProperty<P>>

Returns:

getAssociation

public Optional<Association<P>> getAssociation()

Specified by:

getAssociation in interface PersistentProperty<P extends PersistentProperty<P>>

isCollectionLike

public boolean isCollectionLike()

Description copied from interface: PersistentProperty

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

Specified by:

isCollectionLike in interface PersistentProperty<P extends PersistentProperty<P>>

Returns:

isMap

public boolean isMap()

Description copied from interface: PersistentProperty

Returns whether the property is a Map.

Specified by:

isMap in interface PersistentProperty<P extends PersistentProperty<P>>

Returns:

isArray

public boolean isArray()

Description copied from interface: PersistentProperty

Returns whether the property is an array.

Specified by:

isArray in interface PersistentProperty<P extends PersistentProperty<P>>

Returns:

isEntity

public boolean isEntity()

Description copied from interface: PersistentProperty

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

Specified by:

isEntity in interface PersistentProperty<P extends PersistentProperty<P>>

Returns:

getComponentType

public Optional<Class<?>> getComponentType()

Description copied from interface: PersistentProperty

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.

Specified by:

getComponentType in interface PersistentProperty<P extends PersistentProperty<P>>

Returns:

the component type, the map's key type or Optional.empty() if neither Collection nor Map.

getMapValueType

public Optional<Class<?>> getMapValueType()

Description copied from interface: PersistentProperty

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

Specified by:

Returns:

the map's value type or Optional.empty() if no Map

getActualType

public Class<?> getActualType()

Description copied from interface: PersistentProperty

Returns the actual type of the property. This will be the original property type if no generics were used, the component type for collection-like types and arrays as well as the value type for map properties.

Specified by:

getActualType in interface PersistentProperty<P extends PersistentProperty<P>>

Returns:

usePropertyAccess

public boolean usePropertyAccess()

Description copied from interface: PersistentProperty
