IFSelect_Selection Class Reference

A Selection allows to define a set of Interface Entities. Entities to be put on an output file should be identified in a way as independent from such or such execution as possible. This permits to handle comprehensive criteria, and to replay them when a new variant of an input file has to be processed. More...

Public Member Functions
virtual Interface_EntityIterator	RootResult (const Interface_Graph &G) const =0
	Returns the list of selected entities, computed from Input given as a Graph. Specific to each class of Selection Note that uniqueness of each entity is not required here This method can raise an exception as necessary.
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)
virtual void	FillIterator (IFSelect_SelectionIterator &iter) const =0
	Puts in an Iterator the Selections from which "me" depends (there can be zero, or one, or a list). Specific to each class of Selection.
virtual TCollection_AsciiString	Label () const =0
	Returns a text which defines the criterium applied by a Selection (can be used to be printed, displayed ...) Specific to each class.
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.

Protected Member Functions
virtual Standard_Boolean	HasUniqueResult () const
	Returns True if RootResult guarantees uniqueness for each Entity. Called by UniqueResult. Default answer is False. Can be redefined.

Additional Inherited Members
Public Types inherited from Standard_Transient
typedef void	base_type
	Returns a type descriptor about this object.
Static Public Member Functions inherited from Standard_Transient
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 Selection allows to define a set of Interface Entities. Entities to be put on an output file should be identified in a way as independent from such or such execution as possible. This permits to handle comprehensive criteria, and to replay them when a new variant of an input file has to be processed.

Its input can be, either an Interface Model (the very source), or another-other Selection(s) or any other output. All list computations start from an input Graph (from IFGraph)

CompleteResult()

virtual Interface_EntityIterator IFSelect_Selection::CompleteResult ( const Interface_Graph & G ) const

virtual

Returns the list of entities involved by a Selection, i.e. UniqueResult plus the shared entities (directly or not)

Reimplemented in IFSelect_SelectModelEntities.

FillIterator()

virtual void IFSelect_Selection::FillIterator ( IFSelect_SelectionIterator & iter ) const

pure virtual

Puts in an Iterator the Selections from which "me" depends (there can be zero, or one, or a list). Specific to each class of Selection.

Implemented in IFSelect_SelectBase, IFSelect_SelectCombine, IFSelect_SelectControl, and IFSelect_SelectDeduct.

HasUniqueResult()

virtual Standard_Boolean IFSelect_Selection::HasUniqueResult ( ) const

protectedvirtual

Label()

virtual TCollection_AsciiString IFSelect_Selection::Label ( ) const
