# IFSelect_SignCounter Class Reference

SignCounter gives the frame to count signatures associated
with entities, deducted from them. Ex.: their Dynamic Type.
It can sort a set of Entities according a signature, i.e. :
- list of different values found for this Signature
- for each one, count and list of entities
Results are returned as a SignatureList, which can be queried
on the count (list of strings, count per signature, or list of
entities per signature)
A SignCounter can be filled, either directly from lists, or
from the result of a Selection : hence, its content can be
automatically recomputed as desired
SignCounter works by using a Signature in its method AddSign
Methods can be redefined to, either
- directly compute the value without a Signature
- compute the value in the context of a Graph
.

## Public Member Functions
Standard_EXPORT | IFSelect_SignCounter (const Standard_Boolean withmap=Standard_True, const Standard_Boolean withlist=Standard_False)
| Creates a SignCounter, without proper Signature If <withmap> is True (default), added entities are counted only if they are not yet recorded in the map Map control can be set off if the input garantees uniqueness of data <withlist> is transmitted to SignatureList (option to list entities, not only to count them). .
Standard_EXPORT | IFSelect_SignCounter (const Handle(IFSelect_Signature)&matcher, const Standard_Boolean withmap=Standard_True, const Standard_Boolean withlist=Standard_False)
| Creates a SignCounter, with a predefined Signature Other arguments as for Create without Signature. .
Standard_EXPORT Handle_IFSelect_Signature | Signature () const
| Returns the Signature used to count entities. It can be null. .
Standard_EXPORT void | SetMap (const Standard_Boolean withmap)
| Changes the control status. The map is not cleared, simply its use changes .
virtual Standard_EXPORT Standard_Boolean | AddEntity (const Handle(Standard_Transient)&ent, const Handle(Interface_InterfaceModel)&model)
| Adds an entity by considering its signature, which is given by call to method AddSign Returns True if added, False if already in the map (and map control status set) .
virtual Standard_EXPORT void | AddSign (const Handle(Standard_Transient)&ent, const Handle(Interface_InterfaceModel)&model)
| Adds an entity (already filtered by Map) with its signature. This signature can be computed with the containing model. Its value is provided by the object Signature given at start, if no Signature is defined, it does nothing. Can be redefined (in this case, see also Sign) .
Standard_EXPORT void | AddList (const Handle(TColStd_HSequenceOfTransient)&list, const Handle(Interface_InterfaceModel)&model)
| Adds a list of entities by adding each of the items .
virtual Standard_EXPORT void | AddWithGraph (const Handle(TColStd_HSequenceOfTransient)&list, const Interface_Graph &graph)
| Adds a list of entities in the context given by the graph Default just call basic AddList Can be redefined to get a signature computed with the graph .
Standard_EXPORT void | AddModel (const Handle(Interface_InterfaceModel)&model)
| Adds all the entities contained in a Model .
Standard_EXPORT void | AddFromSelection (const Handle(IFSelect_Selection)&sel, const Interface_Graph &G)
| Adds the result determined by a Selection from a Graph Remark : does not impact at all data from SetSelection & Co .
Standard_EXPORT void | SetSelection (const Handle(IFSelect_Selection)&sel)
| Sets a Selection as input : this causes content to be cleared then the Selection to be ready to compute (but not immediatly) .
Standard_EXPORT Handle_IFSelect_Selection | Selection () const
| Returns the selection, or a null Handle .
Standard_EXPORT void | SetSelMode (const Standard_Integer selmode)
| Changes the mode of working with the selection : -1 just clears optimisation data and nothing else 0 clears it 1 inhibits it for computing (but no clearing) 2 sets it active for computing Default at creation is 0, after SetSelection (not null) is 2 .
Standard_EXPORT Standard_Integer | SelMode () const
| Returns the mode of working with the selection .
Standard_EXPORT Standard_Boolean | ComputeSelected (const Interface_Graph &G, const Standard_Boolean forced=Standard_False)
| Computes from the selection result, if selection is active (mode 2). If selection is not defined (mode 0) or is inhibited (mode 1) does nothing. Returns True if computation is done (or optimised), False else This method is called by ComputeCounter from WorkSession If <forced> is True, recomputes systematically Else (D), if the counter was not cleared and if the former computed result started from the same total size of Graph and same count of selected entities : computation is not redone unless <forced> is given as True .
virtual Standard_EXPORT Handle_TCollection_HAsciiString | Sign (const Handle(Standard_Transient)&ent, const Handle(Interface_InterfaceModel)&model) const
| Determines and returns the value of the signature for an entity as an HAsciiString. This method works exactly as AddSign, which is optimized Can be redefined, accorded with AddSign .
Standard_EXPORT Standard_CString | ComputedSign (const Handle(Standard_Transient)&ent, const Interface_Graph &G)
| Applies AddWithGraph on one entity, and returns the Signature Value which has been recorded To do this, Add is called with SignOnly Mode True during the call, the returned value is LastValue .
Standard_EXPORT const | Handle (Standard_Type)&DynamicType() const
