Interface AttachableDataType

All Known Implementing Classes:
AbstractDatabaseMap, PermissionMap
public interface AttachableDataType
Allows a custom DataType to attach a reference to a UpdatableRecord

This interface is used to allow the UpdatableRecord to automatically detect and trigger the attachment so that the DataType can mark itself as changed when an internal state is updated which requires storage

It is up to the implmenting class to store the record and fieldIndex variables, override methods which change their internal state, and call Record.changed(int, boolean) when appropriate
