Detailed Description

Gives basic data structure for operating and storing graph results (usage is normally internal) Entities are Mapped according their Number in the Model.

Each Entity from the Model can be known as "Present" or not; if it is, it is Mapped with a Status : an Integer which can be used according to needs of each algorithm In addition, the Graph brings a BitMap which can be used by any caller

Also, it is bound with two lists : a list of Shared Entities (in fact, their Numbers in the Model) which is filled by a ShareTool, and a list of Sharing Entities, computed by deduction from the Shared Lists

Moreover, it is possible to redefine the list of Entities Shared by an Entity (instead of standard answer by general service Shareds) : this new list can be empty; it can be changed or reset (i.e. to come back to standard answer)

Interface_Graph::Interface_Graph ( const Interface_Graph agraph,
const Standard_Boolean  copied = Standard_False

  • entities already present with status = "newstat" remain unchanged
  • entities already present with status different form "newstat" have their status modified : if cumul is True, to former status + overlapstat (cumul) if cumul is False, to overlapstat (enforce) (Note : works as GetEntity, shared = False, for each entity)
