Public Member Functions
void	Add (const occ::handle< SelectMgr_Filter > &afilter)
	Adds the filter afilter to a filter object created by a filter class inheriting this framework.

void	Remove (const occ::handle< SelectMgr_Filter > &aFilter)
	Removes the filter aFilter from this framework.

bool	IsEmpty () const
	Returns true if this framework is empty.

bool	IsIn (const occ::handle< SelectMgr_Filter > &aFilter) const
	Returns true if the filter aFilter is in this framework.

const NCollection_List< occ::handle< SelectMgr_Filter > > &	StoredFilters () const
	Returns the list of stored filters from this framework.

void	Clear ()
	Clears the filters used in this framework.

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 SelectMgr_Filter
virtual bool	IsOk (const occ::handle< SelectMgr_EntityOwner > &anObj) const =0
	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.

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.

Detailed Description

A framework to define a compound filter composed of two or more simple filters.

Member Function Documentation

◆ ActsOn()

bool SelectMgr_CompositionFilter::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.

◆ Add()

void SelectMgr_CompositionFilter::Add ( const occ::handle< SelectMgr_Filter > & afilter )

Adds the filter afilter to a filter object created by a filter class inheriting this framework.

◆ Clear()

void SelectMgr_CompositionFilter::Clear ( )

Clears the filters used in this framework.

◆ IsEmpty()

bool SelectMgr_CompositionFilter::IsEmpty ( ) const

Returns true if this framework is empty.

◆ IsIn()

bool SelectMgr_CompositionFilter::IsIn ( const occ::handle< SelectMgr_Filter > & aFilter ) const

Returns true if the filter aFilter is in this framework.

◆ Remove()

void SelectMgr_CompositionFilter::Remove ( const occ::handle< SelectMgr_Filter > & aFilter )

Removes the filter aFilter from this framework.

◆ StoredFilters()

const NCollection_List< occ::handle< SelectMgr_Filter > > & SelectMgr_CompositionFilter::StoredFilters ( ) const

inline

Returns the list of stored filters from this framework.
