EdifNameClashPolicy

public class BasicEdifNameClashPolicy
extends java.lang.Object
implements EdifNameClashPolicy

Defines standard name clashing policies for EDIF name spaces. Clashing rules (according to ngdbuild) for each EDIF name space: EdifCellInstances in an EdifCell single-single - error single-new - error single-old - warning, auto-rename new-new - error old-old - warning, auto-rename old-new - none EdifNets in an EdifCell single-single - warning, auto-rename single-new - none single-old - warning, auto-rename new-new - none old-old - warning, auto-rename old-new - none EdifLibraries in an EdifLibraryManager single-single - error single-new - error single-old - none new-new - error old-old - none old-new - none EdifCells in an EdifLibrary single-single - error single-new - error single-old - none new-new - error old-old - none old-new - none EdifPorts in an EdifCellInterface single-single - error single-new - error single-old - error new-new - error old-old - error old-new - none This class is designed to provide a set of policies that can be used for each EDIF namespace. Because of the map implementation of cell instance and net collections, new-new, new-single, and single-single combinations should never be allowed even though ngdbuild allows new-new and single-new duplications for nets. With this taken into account, there are really only two basic policies that need to be used by the EDIF name spaces. They are the anyButOldWithNewClashPolicy (to be used by EdifNets in an EdifCell, EdifCellInstances in an EdifCell, EdifPorts in an EdifCellInterface) and the singleAndNewClashPolicy (to be used by: EdifLibraries in an EdifLibraryManager, EdifCells in an EdifLibrary)
