public class SingleValuedAttributeModelUpdateStrategy extends Object implements IModelUpdateStrategy
IModelUpdateStrategy for single-valued EAttributes.
This strategy is tolerant in the sense that it will not throw exceptions if the input is not a supported
AttributeChange. In this case, this strategy will return false on
#canUpdate(Diff, MergeViewerSide) and return a command on
#getModelUpdateCommand(Diff, Object, MergeViewerSide) that specifies false on
Command.canExecute(). Therefore, it can be used as default strategy.
