Public Member Functions
	StdSelect_EdgeFilter (const StdSelect_TypeOfEdge Edge)
	Constructs an edge filter object defined by the type of edge Edge.
void	SetType (const StdSelect_TypeOfEdge aNewType)
	Sets the type of edge aNewType. aNewType is to be highlighted in selection.
StdSelect_TypeOfEdge	Type () const
	Returns the type of edge to be highlighted in selection.
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. When an object is detected by the mouse - in AIS, this is done through a context selector - its owner is passed to the filter as an argument. If the object returns true, it is kept; if not, it is rejected. If you are creating a filter class inheriting this framework, and the daughter class is to be used in an AIS local context, you will need to implement the virtual function ActsOn.
bool	ActsOn (const TopAbs_ShapeEnum aStandardMode) const override
	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_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.

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.

Detailed Description

A framework to define a filter to select a specific type of edge. The types available include:

• any edge
• a linear edge
• a circular edge.

Constructor & Destructor Documentation

StdSelect_EdgeFilter()

StdSelect_EdgeFilter::StdSelect_EdgeFilter

(

const StdSelect_TypeOfEdge

Edge

)

Constructs an edge filter object defined by the type of edge Edge.

Member Function Documentation

ActsOn()

bool StdSelect_EdgeFilter::ActsOn ( const TopAbs_ShapeEnum aStandardMode ) const

overridevirtual

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.

Reimplemented from SelectMgr_Filter.

IsOk()

bool StdSelect_EdgeFilter::IsOk ( const occ::handle< SelectMgr_EntityOwner > & anObj ) const

overridevirtual

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. When an object is detected by the mouse - in AIS, this is done through a context selector - its owner is passed to the filter as an argument. If the object returns true, it is kept; if not, it is rejected. If you are creating a filter class inheriting this framework, and the daughter class is to be used in an AIS local context, you will need to implement the virtual function ActsOn.

Implements SelectMgr_Filter.

SetType()

void StdSelect_EdgeFilter::SetType

(

const StdSelect_TypeOfEdge

aNewType

)

Sets the type of edge aNewType. aNewType is to be highlighted in selection.

Type()

StdSelect_TypeOfEdge StdSelect_EdgeFilter::Type

(

)

const

Returns the type of edge to be highlighted in selection.
