Method Detail

getView

public final org.eclipse.gmf.runtime.notation.View getView()

Specified by:

getView in interface INotationModelRefresher

install

public void install(org.eclipse.emf.transaction.TransactionalEditingDomain editingDomain)

Deprecated. Use TransactionalUpdateManager.

isInstalled

public boolean isInstalled()

Deprecated. Use TransactionalUpdateManager.

uninstall

public void uninstall()

Deprecated. Use TransactionalUpdateManager.

isPrecommitOnly

public boolean isPrecommitOnly()

Specified by:

isPrecommitOnly in interface org.eclipse.emf.transaction.ResourceSetListener

Overrides:

isPrecommitOnly in class org.eclipse.emf.transaction.ResourceSetListenerImpl

transactionAboutToCommit

public org.eclipse.emf.common.command.Command transactionAboutToCommit(org.eclipse.emf.transaction.ResourceSetChangeEvent event)

Specified by:

transactionAboutToCommit in interface org.eclipse.emf.transaction.ResourceSetListener

Overrides:

transactionAboutToCommit in class org.eclipse.emf.transaction.ResourceSetListenerImpl

getFilter

public org.eclipse.emf.transaction.NotificationFilter getFilter()

Specified by:

getFilter in interface org.eclipse.emf.transaction.ResourceSetListener

Overrides:

getFilter in class org.eclipse.emf.transaction.ResourceSetListenerImpl

buildRefreshNotationModelCommand

public abstract org.eclipse.emf.common.command.Command buildRefreshNotationModelCommand()

Creates and returns the command that will update the notational model to reflect changes in the domain model.

Specified by:

buildRefreshNotationModelCommand in interface INotationModelRefresher

shouldHandleNotification

getCreateNotationalElementCommand

protected abstract CreateNotationalElementCommand getCreateNotationalElementCommand(ElementDescriptor descriptor)

Returns a command that will create a notational element to represent the domain model element described by the given ElementDescriptor.

createFilter

protected abstract org.eclipse.emf.transaction.NotificationFilter createFilter()

shouldCreateView

protected abstract boolean shouldCreateView(ElementDescriptor descriptor)

getHost

protected abstract org.eclipse.gmf.runtime.notation.View getHost()
