EOEditingContext.Editors
(informal interface)
Package: com.webobjects.eocontrol
Interface Description
The EOEditingContext.Editors interface defines methods for objects that act as higher-level editors of the objects an EOEditingContext contains. An editing context sends messages to its editors to determine whether they have any changes that need to be saved, and to allow them to flush pending changes before a save (possibly throwing an exception to abort the save). See the EOEditingContext and EODisplayGroup (EOInterface) class specifications for more information.
Editors are not required to provide implementations for all of the methods in the interface. When you write an editor, you don't have to use the implements keyword to specify that the object implements the Editors interface. Instead, simply use the EOEditingContext method addEditor method to assign your object as one of the EOEditingContext's editors and then declare and implement any subset of the methods declared in the Editors interface. An EOEditingContext can determine if the editor doesn't implement a method and only attempts to invoke the methods the editor actually implements.
