    Public Member Functions

     IFSelect_SelectUnion ()
     Creates an empty SelectUnion.
    Interface_EntityIterator RootResult (const Interface_Graph &G) const override
     Returns the list of selected Entities, which is the addition result from all input selections. Uniqueness is guaranteed.
    TCollection_AsciiString Label () const override
     Returns a text defining the criterium : "Union (OR)".
    Public Member Functions inherited from IFSelect_SelectCombine
    int NbInputs () const
     Returns the count of Input Selections.
    occ::handle< IFSelect_SelectionInput (const int numnum) const
     Returns an Input Selection, given its rank in the list.
    int InputRank (const occ::handle< IFSelect_Selection > &sel) const
     Returns the rank of an input Selection, 0 if not in the list. Most generally, its value is meaningless, except for testing the presence of an input Selection :
    void Add (const occ::handle< IFSelect_Selection > &sel, const int atnum=0)
     Adds a Selection to the filling list By default, adds it to the end of the list A Positive rank less then NbInputs gives an insertion rank (InsertBefore : the new <atnum>th item of the list is <sel>).
    bool Remove (const occ::handle< IFSelect_Selection > &sel)
     Removes an input Selection. Returns True if Done, False, if <sel> is not an input for <me>.
    bool Remove (const int numnum)
     Removes an input Selection, given its rank in the list Returns True if Done, False if <num> is out of range.
    void FillIterator (IFSelect_SelectionIterator &iter) const override
     Puts in an Iterator the Selections from which "me" depends That is to say, the list of Input Selections.
    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_Transientoperator= (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_TransientThis () 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.

    Additional Inherited Members

    typedef void base_type
     Returns a type descriptor about this object.
    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.
    Protected Member Functions inherited from IFSelect_SelectCombine
     IFSelect_SelectCombine ()
     Defines an empty SelectCombine.
    bool HasUniqueResult () const override
     Returns always True, because RootResult gives a Unique list.
