    AIS_AttributeFilter Class Reference

    Selects Interactive Objects, which have the desired width or color. The filter questions each Interactive Object in local context to determine whether it has an non-null owner, and if so, whether it has the required color and width attributes. If the object returns true in each case, it is kept. If not, it is rejected. This filter is used only in an open local context. In the Collector viewer, you can only locate Interactive Objects, which answer positively to the filters, which are in position when a local context is open. More...

    Public Member Functions

     AIS_AttributeFilter ()
     Constructs an empty attribute filter object. This filter object determines whether selectable interactive objects have a non-null owner.
     AIS_AttributeFilter (const Quantity_NameOfColor aCol)
     Constructs an attribute filter object defined by the color attribute aCol.
     AIS_AttributeFilter (const double aWidth)
     Constructs an attribute filter object defined by the line width attribute aWidth.
    bool HasColor () const
     Indicates that the Interactive Object has the color setting specified by the argument aCol at construction time.
    bool HasWidth () const
     Indicates that the Interactive Object has the width setting specified by the argument aWidth at construction time.
    void SetColor (const Quantity_NameOfColor theCol)
     Sets the color.
    void SetWidth (const double theWidth)
     Sets the line width.
    void UnsetColor ()
     Removes the setting for color from the filter.
    void UnsetWidth ()
     Removes the setting for width from the filter.
    bool IsOk (const occ::handle< SelectMgr_EntityOwner > &anObj) const override
     Indicates that the selected Interactive Object passes the filter. The owner, anObj, can be either direct or user. A direct owner is the corresponding construction element, whereas a user is the compound shape of which the entity forms a part. If the Interactive Object returns true when detected by the Local Context selector through the mouse, the object is kept; if not, it is rejected.
    Public Member Functions inherited from SelectMgr_Filter
    virtual bool ActsOn (const TopAbs_ShapeEnum aStandardMode) const
     Returns true in an AIS local context, if this filter operates on a type of subshape defined in a filter class inheriting this framework. This function completes IsOk in an AIS local context.
    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.

    Member Function Documentation

    ◆ HasColor()

    bool AIS_AttributeFilter::HasColor ( ) const
