Public Member Functions
	IGESSelect_ViewSorter ()
	Creates a ViewSorter, empty. SetModel remains to be called.

	Adds an item according its type : AddEntity,AddList,AddModel.

bool	AddEntity (const occ::handle< IGESData_IGESEntity > &igesent)
	Adds an IGES entity. Records the view it is attached to. Records directly <ent> if it is a ViewKindEntity or a Drawing Returns True if added, False if already in the map.

	Returns the count of already recorded.

void	SortSingleViews (const bool alsoframes)
	Prepares the result to keep only sets attached to Single Views If <alsoframes> is given True, it keeps also the Drawings as specific sets, in order to get their frames. Entities attached to no single view are put in Remaining List.

void	SortDrawings (const Interface_Graph &G)
	Prepares the result to the sets attached to Drawings : All the single views referenced by a Drawing become bound to the set for this Drawing.

int	NbSets (const bool final) const
	Returns the count of sets recorded, one per distinct item. The Remaining List is not counted. If <final> is False, the sets are attached to distinct views determined by the method Add. If <final> is True, they are the sets determined by the last call to, either SortSingleViews, or SortDrawings.

occ::handle< IGESData_IGESEntity >	SetItem (const int num, const bool final) const
	Returns the Item which is attached to a set of entities For <final> and definition of sets, see method NbSets. This item can be a kind of View or a Drawing.

	Returns the complete content of the determined Sets, which include Duplicated and Remaining (duplication 0) lists For <final> and definition of sets, see method NbSets.

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.

	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

	Returns a type descriptor about this object.

	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

Sorts IGES Entities on the views and drawings. In a first step, it splits a set of entities according the different views they are attached to. Then, packets according single views (+ drawing frames), or according drawings (which refer to the views) can be determined.

It is a TShared, hence it can be a workomg field of a non- mutable object (a Dispatch for instance)

Constructor & Destructor Documentation

◆ IGESSelect_ViewSorter()

IGESSelect_ViewSorter::IGESSelect_ViewSorter ( )

Creates a ViewSorter, empty. SetModel remains to be called.

Member Function Documentation

◆ Add()

bool IGESSelect_ViewSorter::Add ( const occ::handle< Standard_Transient > & ent )

Adds an item according its type : AddEntity,AddList,AddModel.

◆ AddEntity()

bool IGESSelect_ViewSorter::AddEntity ( const occ::handle< IGESData_IGESEntity > & igesent )

Adds an IGES entity. Records the view it is attached to. Records directly <ent> if it is a ViewKindEntity or a Drawing Returns True if added, False if already in the map.

◆ AddList()

void IGESSelect_ViewSorter::AddList ( const occ::handle< NCollection_HSequence< occ::handle< Standard_Transient > > > & list )

Adds a list of entities by adding each of the items.

◆ AddModel()

void IGESSelect_ViewSorter::AddModel ( const occ::handle< Interface_InterfaceModel > & model )

Adds all the entities contained in a Model.

◆ Clear()

void IGESSelect_ViewSorter::Clear ( )

Clears recorded data.

◆ NbEntities()

int IGESSelect_ViewSorter::NbEntities ( ) const

Returns the count of already recorded.

◆ NbSets()

int IGESSelect_ViewSorter::NbSets ( const bool final ) const

Returns the count of sets recorded, one per distinct item. The Remaining List is not counted. If <final> is False, the sets are attached to distinct views determined by the method Add. If <final> is True, they are the sets determined by the last call to, either SortSingleViews, or SortDrawings.

Warning : Drawings directly recorded are also counted as sets, because of their Frame (which is made of Annotations)

◆ SetItem()

occ::handle< IGESData_IGESEntity > IGESSelect_ViewSorter::SetItem	(	const int	num,
		const bool	final ) const

Returns the Item which is attached to a set of entities For <final> and definition of sets, see method NbSets. This item can be a kind of View or a Drawing.

◆ SetModel()

void IGESSelect_ViewSorter::SetModel ( const occ::handle< IGESData_IGESModel > & model )

Sets the Model (for PacketList)

◆ Sets()

occ::handle< IFSelect_PacketList > IGESSelect_ViewSorter::Sets ( const bool final ) const

Returns the complete content of the determined Sets, which include Duplicated and Remaining (duplication 0) lists For <final> and definition of sets, see method NbSets.

◆ SortDrawings()

void IGESSelect_ViewSorter::SortDrawings ( const Interface_Graph & G )

Prepares the result to the sets attached to Drawings : All the single views referenced by a Drawing become bound to the set for this Drawing.

Entities or Views which correspond to no Drawing are put into the Remaining List.

Result can then be read by the methods NbSets,SetItem,SetList, RemainingList(final = True)

◆ SortSingleViews()

void IGESSelect_ViewSorter::SortSingleViews ( const bool alsoframes )

Prepares the result to keep only sets attached to Single Views If <alsoframes> is given True, it keeps also the Drawings as specific sets, in order to get their frames. Entities attached to no single view are put in Remaining List.
