Interface_Graph Class Reference

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)

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)

Constructor & Destructor Documentation

Interface_Graph::Interface_Graph ( const Handle< Interface_InterfaceModel > &  amodel,
const Interface_GeneralLib lib,
const Standard_Boolean  theModeStats = Standard_True 
)

Creates an empty graph, ready to receive Entities from amodel
Note that this way of Creation allows <me> to verify that
Entities to work with are contained in <amodel>
Basic Shared and Sharing lists are obtained from a General
Services Library, given directly as an argument

Interface_Graph::Interface_Graph ( const Handle< Interface_InterfaceModel > &  amodel,
const Handle< Interface_Protocol > &  protocol,
const Standard_Boolean  theModeStats = Standard_True 
)

Same as above, but the Library is defined through a Protocol

Interface_Graph::Interface_Graph ( const Handle< Interface_InterfaceModel > &  amodel,
const Handle< Interface_GTool > &  gtool,
const Standard_Boolean  theModeStats = Standard_True 
)

Same as above, but the Library is defined through a Protocol

Interface_Graph::Interface_Graph ( const Handle< Interface_InterfaceModel > &  amodel,
const Standard_Boolean  theModeStats = Standard_True 
)

Same a above but works with the Protocol recorded in the Model

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

Creates a Graph from another one, getting all its data
Remark that status are copied from <agraph>, but the other
lists (sharing/shared) are copied only if <copied> = True

Standard_Integer Interface_Graph::EntityNumber ( const Handle< Standard_Transient > &  ent) const

Returns the Number of the entity in the Map, computed at
creation time (Entities loaded from the Model)

void Interface_Graph::GetFromEntity ( const Handle< Standard_Transient > &  ent,
const Standard_Boolean  shared,

const Standard_Boolean  shared,
const Standard_Integer  newstat,
const Standard_Integer  overlapstat,
const Standard_Boolean  cumul 
)

Gets an Entity, plus its shared ones (at every level) if
"shared" is True. New items are set to status "newstat".
Items already present in graph are processed as follows :

  • if they already have status "newstat", they remain unchanged
  • if they have another status, this one is modified :
    if cumul is True, to former status + overlapstat (cumul)
    if cumul is False, to overlapstat (enforce)

void Interface_Graph::GetFromIter ( const Interface_EntityIterator iter,
const Standard_Integer  newstat 
)

void Interface_Graph::GetFromIter ( const Interface_EntityIterator iter,
const Standard_Integer  newstat,
const Standard_Integer  overlapstat,
const Standard_Boolean  cumul 
)

Gets Entities given by an EntityIterator and distinguishes
those already present in the Graph :

  • new entities added to the Graph with status "newstst"
  • 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)
