public interface IElementType
- extends
IAdaptable
Interface used to define application-layer types that describe the kinds of
elements that can be displayed, created, modified and destroyed. These types
extend the types defined for any given metamodel, so that
IElementType s can be used to distinguish types of elements
that share the same metaclass.
Each element type defines how model objects that match its type are to be
displayed (by icon URL and display name), as well as how they are to be
created, modified and deleted (by edit helper and an accessor for edit
commands).
There are two known extensions of IElementType. These are
IMetamodelType and ISpecializationType. Each
metamodel type maps directly to an EClass. Each specialization type matches a
metamodel type with further restrictions expressed in a
IElementMatcher class.
Clients should not implement this interface directly, but should extend the
abstract implementation
