Detailed Description

An interface class that acts as a wrapper for an application model.

This is also known as an application model header.

The class provides the knowledge for internalizing and externalizing an application model's data. An instance of the class is used by CApaModelDoor.

A concrete implementation of the class must be supplied by the application model (not the application UI). An instance of the class is constructed by a factory object that implements the MApaModelHeaderFactory interface; the factory object is also supplied by the application model (not the application UI).

AppId ( )

TApaAppIdentifier

AppId

(

)

const [pure virtual]

Gets the identity of the application associated with the application model.

Return Value: The application identity.

DetachFromStoreL ( CPicture::TDetach )

void

DetachFromStoreL

(

CPicture::TDetach

aDegree

)

[pure virtual]

Restores the model to the specified degree.

An implementation of this function should propagate this call to all components of the model.

Parameters
aDegree	The degree to which restoration is needed.

StoreL ( CStreamStore &, CStreamDictionary & )

void	StoreL	(	CStreamStore &	aStore,
			CStreamDictionary &	aDict
		)	const [pure virtual]

Stores the model and its components in the specified store.

Parameters
aStore	The store in which the model's components are to be stored.
aDict	The stream dictionary into which stream IDs and associated UIDs are put.
