Interface Summary

ICMIGenericModelClass	Interface for a generic model class.
ICMIGenericModelClass02	Extended version of ICMIGenericModelClass that provides sorted access to relations and access to relation role specific model object managers.
ICMIModel	Manages and contains all Model classes, which together form a Common Model.
ICMIModel02	Extended version of ICMIModel that provides class specific model object managers.
ICMIModelClass	Represents a Model class in a Model.
ICMIModelClassExecutable	Allows access to some executable behavior of model classes.
ICMIModelClassWrapper	Common interface for types that wrap a model class (and usually delegate to it).
ICMIModelObjectCollection	Represents a collection of instances of model classes in a model.
ICMIModelObjectCollection02	Extended version of ICMIModelObjectCollection that provides access to a collection specific model object manager.
ICMIModelObjectManager	Allows creation and deletion of objects in a specific scope.
ICMIQuery	Represents a query in a Model.
ICMIWrappableModelClass	Interface for model classes that are prepared to be wrapped by some technology specific wrapper.

Package com.sap.tc.cmi.model Description

Contains interfaces to be implemented for the data part of a model implementing the Common Model Interface CMI.

Besides interfaces representing the model itself, model classes and collections of model objects there are interfaces used in the following contexts

• Executable model classes and queries (ICMIModelClassExecutable and its extension ICMIQuery): These offer a notion for execution of a model class in the sense of a "function" and - in the case of a query - define access to input and output via model class relations.
• Life cycle management for model objects (ICMIModelObjectManager): Used for creation or deletion of model objects in different scopes.

Some interfaces are named ICMI*02; these are extensions of interfaces named ICMI* which originate from previously released CMI versions. The old interfaces are still there for compatibility reasons: CMI implementations based on previous releases can run on newer releases without implementation changes. New CMI implementations should always implement the newer interfaces if they need to implement the respective interface at all.

Note the differences between a typed and generic model when implementing the interfaces in this package. For example, typed models may but don't have to supply model class metadata which means they may but don't have to implement ICMIModelClass whereas generic models must implement ICMIGenericModelClass02 (or its previous version ICMIGenericModelClass).
Further note that a typed model may also offer generic access to model class properties and relations which means typed and generic do not exclude each other.
