Method Details

canExecute
Description copied from interface:IFeatureDecides if the current feature can execute with the given context.- Specified by:
canExecutein interfaceIFeature- Parameters:
context- this is the general input for this method- Returns:
- true if the feature can be executed, false if not
- See Also:
-
execute
Description copied from interface:IFeatureExecutes the current feature with the given context. -
getName
Description copied from interface:INameGets the name.- Specified by:
getNamein interfaceIName- Overrides:
getNamein classAbstractFeature- Returns:
- the name
-
getFromClipboard
Gets original content from clipboard.- Returns:
- the content from clipboard
- Throws:
IllegalStateException- if not called from UI thread
-
getCopiesFromClipBoard
Duplicates the clipboard's content.- Parameters:
target- an object acting as composite parent for the copies.nullif the copied elements should be top-level elements.- Returns:
- the copy result or
nullin case of an empty clipboard - Throws:
IllegalStateException- if not called from UI thread- See Also:
-
isCompositionAllowed
protected boolean isCompositionAllowed(org.eclipse.emf.ecore.EObject parent, org.eclipse.emf.ecore.EObject[] objects) Answers whether at least one of the given objects can be aggregated below the given parent as composite children.- Parameters:
parent- the composite parentobjects- the objects to check- Returns:
trueif at least one object may be a composite child ofparent- See Also:
-
isResolvable
protected boolean isResolvable(org.eclipse.emf.ecore.EObject object) Checks if the givenEObjectcan be resolved in the localEditingDomainof the currentDiagramBehavior. Pasting an EObject that is not resolvable (e.g. it was just created in another editor and has not yet been persisted) may cause issues with the graphical presentation of the new object: the Graphiti update will not find any domain object and will therefore mark the object as update needed (an update triggered will then remove the shape from the diagram). At least some special handling will be needed for the paste process of such an object: e.g. the domain object could be created along with its graphical presentation duringIPasteFeature.paste(IPasteContext), but that may lead (depending on the domain) to other follow-up issues.
Clients may use this method to check for such a situation and react accordingly. Created as part of the fix for Bugzilla 375533.- Parameters:
object- The object to check- Returns:
truein case the given object can be resolved in the editing domain of the current editor,falseotherwise.- Since:
