	IFSelect_SelectPointed ()
	Creates a SelectPointed.

void	Clear ()
	Clears the list of selected items Also says the list is unset All Add* methods and SetList say the list is set.

Standard_Boolean	IsSet () const
	Tells if the list has been set. Even if empty.

void	SetEntity (const Handle< Standard_Transient > &item)
	As SetList but with only one entity If <ent> is Null, the list is said as being set but is empty.

void	SetList (const Handle< TColStd_HSequenceOfTransient > &list)
	Sets a given list to define the list of selected items be empty or null : in this case, the list is said as being set, but it is empty.

Standard_Boolean	Add (const Handle< Standard_Transient > &item)
	Adds an item. Returns True if Done, False if is already in the selected list.

Standard_Boolean	Remove (const Handle< Standard_Transient > &item)
	Removes an item. Returns True if Done, False if was not in the selected list.

Standard_Boolean	Toggle (const Handle< Standard_Transient > &item)
	Toggles status of an item : adds it if not pointed or removes it if already pointed. Returns the new status (Pointed or not)

Standard_Boolean	AddList (const Handle< TColStd_HSequenceOfTransient > &list)
	Adds all the items defined in a list. Returns True if at least one item has been added, False else.

Standard_Boolean	RemoveList (const Handle< TColStd_HSequenceOfTransient > &list)
	Removes all the items defined in a list. Returns True if at least one item has been removed, False else.

	Returns an item given its rank, or a Null Handle.

void	Update (const Handle< Interface_CopyControl > &control)
	Rebuilds the selected list. Any selected entity which has a bound result is replaced by this result, else it is removed.

void	Update (const Handle< IFSelect_Transformer > &trf)
	Rebuilds the selected list, by querying a Transformer (same principle as from a CopyControl)

Interface_EntityIterator	RootResult (const Interface_Graph &G) const override
	Returns the list of selected items. Only the selected entities which are present in the graph are given (this result assures uniqueness).

TCollection_AsciiString	Label () const override
	Returns a text which identifies the type of selection made. It is "Pointed Entities".

void	FillIterator (IFSelect_SelectionIterator &iter) const override
	Puts in an Iterator the Selections from which "me" depends This list is empty for all SelectBase type Selections.

Public Member Functions inherited from IFSelect_Selection
Interface_EntityIterator	UniqueResult (const Interface_Graph &G) const
	Returns the list of selected entities, each of them being unique. Default definition works from RootResult. According HasUniqueResult, UniqueResult returns directly RootResult, or build a Unique Result from it with a Graph.

virtual Interface_EntityIterator	CompleteResult (const Interface_Graph &G) const
	Returns the list of entities involved by a Selection, i.e. UniqueResult plus the shared entities (directly or not)

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

This type of Selection is intended to describe a direct selection without an explicit criterium, for instance the result of picking viewed entities on a graphic screen.

It can also be used to provide a list as internal alternate input : this use implies to clear the list once queried

Returns an item given its rank, or a Null Handle.

◆ Label()

TCollection_AsciiString IFSelect_SelectPointed::Label ( ) const

overridevirtual

Returns a text which identifies the type of selection made. It is "Pointed Entities".

Implements IFSelect_Selection.

◆ NbItems()

Standard_Integer IFSelect_SelectPointed::NbItems ( ) const

Returns the count of selected items.

◆ Rank()

Standard_Integer IFSelect_SelectPointed::Rank ( const Handle< Standard_Transient > & item ) const

Returns the rank of an item in the selected list, or 0.

◆ Remove()

Removes an item. Returns True if Done, False if was not in the selected list.

◆ RemoveList()

Standard_Boolean IFSelect_SelectPointed::RemoveList ( const Handle< TColStd_HSequenceOfTransient > & list )

Removes all the items defined in a list. Returns True if at least one item has been removed, False else.

◆ RootResult()

Interface_EntityIterator IFSelect_SelectPointed::RootResult ( const Interface_Graph & G ) const

overridevirtual

Returns the list of selected items. Only the selected entities which are present in the graph are given (this result assures uniqueness).

Implements IFSelect_Selection.

◆ SetEntity()

void IFSelect_SelectPointed::SetEntity ( const Handle< Standard_Transient > & item )

As SetList but with only one entity If <ent> is Null, the list is said as being set but is empty.

◆ SetList()

void IFSelect_SelectPointed::SetList ( const Handle< TColStd_HSequenceOfTransient > & list )

Sets a given list to define the list of selected items

be empty or null : in this case, the list is said as being set, but it is empty.

To use it as an alternate input, one shot :

SetList or SetEntity to define the input list
RootResult to get it
then Clear to drop it

◆ Toggle()

Standard_Boolean IFSelect_SelectPointed::Toggle ( const Handle< Standard_Transient > & item )

Toggles status of an item : adds it if not pointed or removes it if already pointed. Returns the new status (Pointed or not)

◆ ToggleList()

Standard_Boolean IFSelect_SelectPointed::ToggleList ( const Handle< TColStd_HSequenceOfTransient > & list )

Toggles status of all the items defined in a list : adds it if not pointed or removes it if already pointed.

◆ Update() [1/2]

void IFSelect_SelectPointed::Update ( const Handle< IFSelect_Transformer > & trf )

Rebuilds the selected list, by querying a Transformer (same principle as from a CopyControl)

◆ Update() [2/2]

void IFSelect_SelectPointed::Update ( const Handle< Interface_CopyControl > & control )

Rebuilds the selected list. Any selected entity which has a bound result is replaced by this result, else it is removed.
