AbstractDrillDownFeature

public AbstractDrillDownFeature(IFeatureProvider fp)

Creates a new AbstractDrillDownFeature.

Parameters:

fp - the feature provider

Method Detail

getName

public java.lang.String getName()

Description copied from interface: IName

Gets the name.

Specified by:

getName in interface IName

Overrides:

getName in class AbstractFeature

Returns:

the name

execute

public void execute(ICustomContext context)

Description copied from interface: ICustomFeature

Execute.

Parameters:

context - the context

canExecute

public boolean canExecute(ICustomContext context)

Description copied from interface: ICustomFeature

Can execute.

Specified by:

canExecute in interface ICustomFeature

Overrides:

canExecute in class AbstractCustomFeature

Parameters:

context - the context

Returns:

true, if successful

hasDoneChanges

public boolean hasDoneChanges()

Description copied from interface: IFeature

Is queried by the framework after a feature has been executed to find out if this feature should appear in the undo stack. By default all features should appear there (see implementation in AbstractFeature), but single features may decide to override this behavior. Note that this is a dynamic attribute of the feature that is queried each time after the feature has been executed.

IMPORTANT NOTE: The implementor of the feature is responsible for correctly implementing this method! It will lead to inconsistencies if this method returns false although the feature did changes.

Specified by:

hasDoneChanges in interface IFeature

Overrides:

hasDoneChanges in class AbstractFeature

Returns:

true if the feature should appear in the undo stack, false otherwise

getLinkedDiagrams

protected java.util.Collection<Diagram> getLinkedDiagrams(PictogramElement pe)

Returns a list of all diagrams, which are connected to the given pictogram element. This means, that the diagrams and the pictogram element have at least one linked business object in common.

Parameters:

pe - The pictogram element for which to return the connected diagrams.

Returns:

A list of all diagrams, which are connected to the given pictogram element.

getDiagrams

protected abstract java.util.Collection<Diagram> getDiagrams()

Returns all diagrams which are considered for navigation.

Returns:

the diagrams

getTransActionalEditingDomainForNewDiagram

protected TransactionalEditingDomain getTransActionalEditingDomainForNewDiagram()
