Method Detail

getDefaultValue

public Object getDefaultValue()

Description copied from interface: FieldAccessor

Returns a default implementation for a field or null if none is provided.

This default implementation is returned in detached mode by the DetachedEntityState when the value of the field is get.

Specified by:

getDefaultValue in interface FieldAccessor

Returns:

a default implementation for a field or null if none is provided.

setValue

public Object setValue(Object entity,
                       Object newVal,
                       MappingPolicy mappingPolicy)

Description copied from interface: FieldAccessor

handles field write modification.

Specified by:

setValue in interface FieldAccessor

Returns:

the written value or a DoReturn wrapper with the written value or null. DoReturn indicates that the aspect should not proceed to the original field access but instead return immediately.

loadEndNodeToRelationshipEntityMapping

protected Map<org.neo4j.graphdb.Node,Object> loadEndNodeToRelationshipEntityMapping(Object newVal,
                                                                                    org.neo4j.graphdb.Node startNode)

isWriteable

public boolean isWriteable(Object entity)

Specified by:

isWriteable in interface FieldAccessor

Returns:

false for read only or computed fields, true otherwise

getValue

public Object getValue(Object entity,
                       MappingPolicy mappingPolicy)

Specified by:

getValue in interface FieldAccessor

Returns:

the value or a DoReturn wrapper with the value for the field. DoReturn indicates that the aspect should not proceed to the original field access but instead return immediately.

createManagedSet

protected <T> ManagedFieldAccessorSet<T> createManagedSet(Object entity,
                                                          Set<T> result,
                                                          MappingPolicy mappingPolicy)
