Trait that indicates that the children represented by this field should be deleted when the parent is deleted.
Simple OneToMany support for children from the same table
This is the base class to use for fields that represent one-to-many or parent-child relationships.
This is the base class to use for fields that represent one-to-many or parent-child relationships. Maintains a list of children, tracking pending additions and deletions, and keeping their foreign key pointed to this mapper. Implements Buffer, so the children can be managed as one. Most users will use MappedOneToMany, however to support children from multiple tables it is necessary to use MappedOneToManyBase.
Adds behavior to delete orphaned fields before save.
