Inheritance diagram for SelectMgr_AndFilter:

Public Member Functions
	SelectMgr_AndFilter ()
	Constructs an empty selection filter object for two or more types of entity.
Standard_Boolean	IsOk (const 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 Standard_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 SelectMgr_CompositionFilter
void	Add (const Handle< SelectMgr_Filter > &afilter)
	Adds the filter afilter to a filter object created by a filter class inheriting this framework.
void	Remove (const Handle< SelectMgr_Filter > &aFilter)
	Removes the filter aFilter from this framework.
Standard_Boolean	IsEmpty () const
	Returns true if this framework is empty.
Standard_Boolean	IsIn (const Handle< SelectMgr_Filter > &aFilter) const
	Returns true if the filter aFilter is in this framework.
const SelectMgr_ListOfFilter &	StoredFilters () const
	Returns the list of stored filters from this framework.
void	Clear ()
	Clears the filters used in this framework.
virtual Standard_Boolean	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 ()
	Destructor must be virtual.
virtual const opencascade::handle< Standard_Type > &	DynamicType () const
	Returns a type descriptor about this object.
Standard_Boolean	IsInstance (const opencascade::handle< Standard_Type > &theType) const
	Returns a true value if this is an instance of Type.
Standard_Boolean	IsInstance (const Standard_CString theTypeName) const
	Returns a true value if this is an instance of TypeName.
Standard_Boolean	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_Boolean	IsKind (const Standard_CString 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.
Standard_Integer	GetRefCount () const noexcept
	Get the reference counter of this object.
void	IncrementRefCounter () noexcept
	Increments the reference counter of this object.
Standard_Integer	DecrementRefCounter () noexcept
	Decrements the reference counter of this object; returns the decremented value.
virtual void	Delete () const
	Memory deallocator for transient classes.

Detailed Description

A framework to define a selection filter for two or more types of entity.

Constructor & Destructor Documentation

SelectMgr_AndFilter()

SelectMgr_AndFilter::SelectMgr_AndFilter

(

)

Constructs an empty selection filter object for two or more types of entity.

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 Standard_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.
