Detailed Description

This class is intended to
explore shapes and convert different representations
(list, sequence, compound) of complex shapes. It provides tools for:

obtaining type of the shapes in context of TopoDS_Compound,
exploring shapes in context of TopoDS_Compound,
converting different representations of shapes (list, sequence, compound).

Creates an object Explorer

Member Function Documentation

TopoDS_Shape ShapeExtend_Explorer::CompoundFromSeq ( const Handle< TopTools_HSequenceOfShape > & seqval ) const

Converts a sequence of Shapes to a Compound

void ShapeExtend_Explorer::DispatchList	(	const Handle< TopTools_HSequenceOfShape > &	list,
		Handle< TopTools_HSequenceOfShape > &	vertices,
		Handle< TopTools_HSequenceOfShape > &	edges,
		Handle< TopTools_HSequenceOfShape > &	wires,

		Handle< TopTools_HSequenceOfShape > &	solids,
		Handle< TopTools_HSequenceOfShape > &	compsols,
		Handle< TopTools_HSequenceOfShape > &	compounds
	)		const

Dispatches starting list of shapes according to their type,
to the appropriate resulting lists
For each of these lists, if it is null, it is firstly created
else, new items are appended to the already existing ones

void ShapeExtend_Explorer::ListFromSeq	(	const Handle< TopTools_HSequenceOfShape > &	seqval,
		TopTools_ListOfShape &	lisval,
		const Standard_Boolean	clear = `Standard_True`
	)		const

Converts a Sequence of Shapes to a List of Shapes
<clear> if True (D), commands the list to start from scratch
else, the list is cumulated

Handle_TopTools_HSequenceOfShape ShapeExtend_Explorer::SeqFromCompound	(	const TopoDS_Shape &	comp,
		const Standard_Boolean	expcomp
	)		const

Converts a Compound to a list of Shapes
if <comp> is not a compound, the list contains only <comp>
if <comp> is Null, the list is empty
if <comp> is a Compound, its sub-shapes are put into the list
then if <expcomp> is True, if a sub-shape is a Compound, it
is not put to the list but its sub-shapes are (recursive)

Handle_TopTools_HSequenceOfShape ShapeExtend_Explorer::SeqFromList ( const TopTools_ListOfShape & lisval ) const

Converts a List of Shapes to a Sequence of Shapes

TopAbs_ShapeEnum ShapeExtend_Explorer::ShapeType	(	const TopoDS_Shape &	shape,
		const Standard_Boolean	compound
	)		const

Returns the type of a Shape: true type if <compound> is False
If <compound> is True and <shape> is a Compound, iterates on
its items. If all are of the same type, returns this type.
Else, returns COMPOUND. If it is empty, returns SHAPE
For a Null Shape, returns SHAPE

TopoDS_Shape ShapeExtend_Explorer::SortedCompound	(	const TopoDS_Shape &	shape,
		const TopAbs_ShapeEnum	type,
		const Standard_Boolean	explore,
		const Standard_Boolean	compound
	)		const

Builds a COMPOUND from the given shape.
It explores the shape level by level, according to the
<explore> argument. If <explore> is False, only COMPOUND
items are explored, else all items are.
The following shapes are added to resulting compound:

shapes which comply to <type>
if <type> is WIRE, considers also free edges (and makes wires)
if <type> is SHELL, considers also free faces (and makes shells)
If <compound> is True, gathers items in compounds which
correspond to starting COMPOUND,SOLID or SHELL containers, or
items directly contained in a Compound
