Method Detail

shouldDeleteSemantic

protected boolean shouldDeleteSemantic()

Description copied from class: ComponentEditPolicy

Return true if the host element should delete its semantic element; otherwise false to delete its view. A true return value implies that the host's parent is using a canonical model manager.

Overrides:

shouldDeleteSemantic in class ComponentEditPolicy

Returns:

true or false

getDeleteCommand

protected Command getDeleteCommand(GroupRequest request)

Returns a command to delete the view. Since this command has no semantic element we want to avoid the prompt regarding "delete from model".
