A SelectRootComps sorts the Entities which are part of Strong Components, local roots of a set of Entities : they can be Single Components (containing one Entity) or Cycles This class gives a more secure result than SelectRoots (which considers only Single Components) but is longer to work : it can be used when there can be or there are cycles in a Model For each cycle, one Entity is given arbitrarily Reject works as for SelectRoots : Strong Components defined in the input list which are not local roots are given.

Public Member Functions | |
| IFSelect_SelectRootComps () | |
| Creates a SelectRootComps. | |
| Interface_EntityIterator | RootResult (const Interface_Graph &G) const override |
| Returns the list of local root strong components, by one Entity per component. It is redefined for a purpose of efficiency : calling a Sort routine for each Entity would cost more resources than to work in once using a Map RootResult takes in account the Direct status. | |
| bool | Sort (const int rank, const occ::handle< Standard_Transient > &ent, const occ::handle< Interface_InterfaceModel > &model) const override |
| Returns always True, because RootResult has done work. | |
| TCollection_AsciiString | ExtractLabel () const override |
| Returns a text defining the criterium : "Local Root Components". | |
 Public Member Functions inherited from IFSelect_SelectExtract | |
| bool | IsDirect () const |
| Returns True if Sort criterium is Direct, False if Reverse. | |
| void | SetDirect (const bool direct) |
| Sets Sort criterium sense to a new value (True : Direct , False : Reverse) | |
| virtual bool | SortInGraph (const int rank, const occ::handle< Standard_Transient > &ent, const Interface_Graph &G) const |
| Works as Sort but works on the Graph Default directly calls Sort, but it can be redefined If SortInGraph is redefined, Sort should be defined even if not called (to avoid deferred methods in a final class) | |
| TCollection_AsciiString | Label () const override |
| Returns a text saying "Picked" or "Removed", plus the specific criterium returned by ExtractLabel (see below) | |
| Public Member Functions inherited from IFSelect_SelectDeduct | |
| void | SetInput (const occ::handle< IFSelect_Selection > &sel) |
| Defines or Changes the Input Selection. | |
| occ::handle< IFSelect_Selection > | Input () const |
| Returns the Input Selection. | |
| bool | HasInput () const |
| Returns True if the Input Selection is defined, False else. | |
| bool | HasAlternate () const |
| Tells if an Alternate List has been set, i.e. : the Alternate Definition is present and set. | |
| occ::handle< IFSelect_SelectPointed > & | Alternate () |
| Returns the Alternate Definition It is returned modifiable, hence an already defined SelectPointed can be used But if it was not yet defined, it is created the first time. | |
| Interface_EntityIterator | InputResult (const Interface_Graph &G) const |
| Returns the Result determined by Input Selection, as Unique if Input Selection is not defined, returns an empty list. | |
| void | FillIterator (IFSelect_SelectionIterator &iter) const override |
| Puts in an Iterator the Selections from which "me" depends This list contains one Selection : the InputSelection. | |
| Public Member Functions inherited from IFSelect_Selection | |
| Interface_EntityIterator | UniqueResult (const Interface_Graph &G) const |
| Returns the list of selected entities, each of them being unique. Default definition works from RootResult. According HasUniqueResult, UniqueResult returns directly RootResult, or build a Unique Result from it with a Graph. | |
| virtual Interface_EntityIterator | CompleteResult (const Interface_Graph &G) const |
| Returns the list of entities involved by a Selection, i.e. UniqueResult plus the shared entities (directly or not) | |
| Public Member Functions inherited from Standard_Transient | |
| Standard_Transient () | |
| Empty constructor. | |
| Standard_Transient (const Standard_Transient &) | |
| Copy constructor – does nothing. | |
| Standard_Transient & | operator= (const Standard_Transient &) |
| Assignment operator, needed to avoid copying reference counter. | |
| virtual | ~Standard_Transient ()=default |
| Destructor must be virtual. | |
| virtual const opencascade::handle< Standard_Type > & | DynamicType () const |
| Returns a type descriptor about this object. | |
| bool | IsInstance (const opencascade::handle< Standard_Type > &theType) const |
| Returns a true value if this is an instance of Type. | |
| bool | IsInstance (const char *const theTypeName) const |
| Returns a true value if this is an instance of TypeName. | |
| bool | IsKind (const opencascade::handle< Standard_Type > &theType) const |
| Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism. | |
| bool | IsKind (const char *const theTypeName) const |
| Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism. | |
| Standard_Transient * | This () const |
| Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero. | |
| int | GetRefCount () const noexcept |
| Get the reference counter of this object. | |
| void | IncrementRefCounter () noexcept |
| Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations. | |
| int | DecrementRefCounter () noexcept |
| Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement. | |
| virtual void | Delete () const |
| Memory deallocator for transient classes. | |
Protected Member Functions | |
| bool | HasUniqueResult () const override |
| Returns True, RootResult assuring uniqueness. | |
| Protected Member Functions inherited from IFSelect_SelectExtract | |
| IFSelect_SelectExtract () | |
| Initializes a SelectExtract : enforces the sort to be Direct. | |
Additional Inherited Members | |
| Public Types inherited from Standard_Transient | |
| typedef void | base_type |
| Returns a type descriptor about this object. | |
| Static Public Member Functions inherited from Standard_Transient | |
| static constexpr const char * | get_type_name () |
| Returns a type descriptor about this object. | |
| static const opencascade::handle< Standard_Type > & | get_type_descriptor () |
| Returns type descriptor of Standard_Transient class. | |
