Detailed Description

Rebuilds a Shape by making pre-defined substitutions on some of its components.

In a first phase, it records requests to replace or remove some individual shapes For each shape, the last given request is recorded Requests may be applied "Oriented" (i.e. only to an item with the SAME orientation) or not (the orientation of replacing shape is respectful of that of the original one)

Then, these requests may be applied to any shape which may contain one or more of these individual shapes

Constructor & Destructor Documentation

BRepTools_ReShape::BRepTools_ReShape ( )

Returns an empty Reshape.

Member Function Documentation

virtual TopoDS_Shape BRepTools_ReShape::Apply ( const TopoDS_Shape shape,
const TopAbs_ShapeEnum  until,
const Standard_Integer  buildmode 
)
virtual

Applies the substitutions requests to a shape.

<until> gives the level of type until which requests are taken into account. For subshapes of the type <until> no rebuild and futher exploring are done. ACTUALLY, NOT IMPLEMENTED BELOW TopAbs_FACE

<buildmode> says how to do on a SOLID,SHELL ... if one of its sub-shapes has been changed: 0: at least one Replace or Remove -> COMPOUND, else as such 1: at least one Remove (Replace are ignored) -> COMPOUND 2: Replace and Remove are both ignored If Replace/Remove are ignored or absent, the result as same type as the starting shape

Reimplemented in ShapeBuild_ReShape.

virtual TopoDS_Shape BRepTools_ReShape::Apply ( const TopoDS_Shape shape,
const TopAbs_ShapeEnum  until = TopAbs_SHAPE 
)
virtual

Applies the substitutions requests to a shape.

<until> gives the level of type until which requests are taken into account. For subshapes of the type <until> no rebuild and futher exploring are done.

NOTE: each subshape can be replaced by shape of the same type or by shape containing only shapes of that type (for example, TopoDS_Edge can be replaced by TopoDS_Edge, TopoDS_Wire or TopoDS_Compound containing TopoDS_Edges). If incompatible shape type is encountered, it is ignored and flag FAIL1 is set in Status.

Reimplemented in ShapeBuild_ReShape.

virtual void BRepTools_ReShape::Clear ( )
virtual

Clears all substitutions requests.

virtual Standard_Boolean BRepTools_ReShape::IsRecorded ( const TopoDS_Shape shape) const
virtual

Tells if a shape is recorded for Replace/Remove.

virtual Standard_Boolean& BRepTools_ReShape::ModeConsiderLocation ( )
virtual

Returns (modifiable) the flag which defines whether Location of shape take into account during replacing shapes.

virtual Standard_Boolean& BRepTools_ReShape::ModeConsiderOrientation ( )
virtual

Returns (modifiable) the flag which defines whether Orientation of shape take into account during replacing shapes.

virtual void BRepTools_ReShape::Remove ( const TopoDS_Shape shape,
const Standard_Boolean  oriented = Standard_False 
)
virtual

Sets a request to Remove a Shape If <oriented> is True, only for a shape with the SAME orientation. Else, whatever the orientation.

virtual void BRepTools_ReShape::Replace ( const TopoDS_Shape shape,
const TopoDS_Shape newshape,
const Standard_Boolean  oriented = Standard_False 
)
virtual

Sets a request to Replace a Shape by a new one If <oriented> is True, only if the orientation is the same Else, whatever the orientation, and the new shape takes the same orientation as <newshape> if the replaced one has the same as <shape>, else it is reversed.

virtual Standard_Integer BRepTools_ReShape::Status ( const TopoDS_Shape shape,
TopoDS_Shape newsh,
const Standard_Boolean  last = Standard_False 
)
virtual

Returns a complete substitution status for a shape 0 : not recorded, <newsh> = original <shape> < 0: to be removed, <newsh> is NULL

0: to be replaced, <newsh> is a new item

If <last> is False, returns status and new shape recorded in the map directly for the shape, if True and status > 0 then recursively searches for the last status and new shape.

Reimplemented in ShapeBuild_ReShape.

virtual TopoDS_Shape BRepTools_ReShape::Value ( const TopoDS_Shape shape) const
virtual

Returns the new value for an individual shape If not recorded, returns the original shape itself If to be Removed, returns a Null Shape Else, returns the replacing item.
