Represents the state of a given selection mode for a Selectable Object. Contains all the sensitive entities available for this mode. An interactive object can have an indefinite number of modes of selection, each representing a "decomposition" into sensitive primitives; each primitive has an Owner (SelectMgr_EntityOwner) which allows us to identify the exact entity which has been detected. Each Selection mode is identified by an index. The set of sensitive primitives which correspond to a given mode is stocked in a SelectMgr_Selection object. By Convention, the default selection mode which allows us to grasp the Interactive object in its entirety will be mode 0. AIS_Trihedron : 4 selection modes. More...

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.

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.

Detailed Description

Represents the state of a given selection mode for a Selectable Object. Contains all the sensitive entities available for this mode. An interactive object can have an indefinite number of modes of selection, each representing a "decomposition" into sensitive primitives; each primitive has an Owner (SelectMgr_EntityOwner) which allows us to identify the exact entity which has been detected. Each Selection mode is identified by an index. The set of sensitive primitives which correspond to a given mode is stocked in a SelectMgr_Selection object. By Convention, the default selection mode which allows us to grasp the Interactive object in its entirety will be mode 0. AIS_Trihedron : 4 selection modes.

mode 0 : selection of a trihedron
mode 1 : selection of the origin of the trihedron
mode 2 : selection of the axes
mode 3 : selection of the planes XOY, YOZ, XOZ when you activate one of modes 1 2 3 4 , you pick AIS objects of type:
AIS_Point
AIS_Axis (and information on the type of axis)
AIS_Plane (and information on the type of plane). AIS_PlaneTrihedron offers 3 selection modes:
mode 0 : selection of the whole trihedron
mode 1 : selection of the origin of the trihedron
mode 2 : selection of the axes - same remarks as for the Trihedron. AIS_Shape : 7 maximum selection modes, depending on the complexity of the shape :
mode 0 : selection of the AIS_Shape
mode 1 : selection of the vertices
mode 2 : selection of the edges
mode 3 : selection of the wires
mode 4 : selection of the faces
mode 5 : selection of the shells
mode 6 : selection of the constituent solids.
