BRepTools_ReShape Class Reference

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

Public Member Functions

 BRepTools_ReShape ()
 Returns an empty Reshape

void Clear ()
 Clears all substitutions requests

void Remove (const TopoDS_Shape &shape, const Standard_Boolean oriented=Standard_False)
 Sets a request to Remove a Shape
If <oriented> is True, only for a shape with the SAME
orientation. Else, whatever the orientation

void Replace (const TopoDS_Shape &shape, const TopoDS_Shape &newshape, const Standard_Boolean oriented=Standard_False)
 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

Standard_Boolean IsRecorded (const TopoDS_Shape &shape) const
 Tells if a shape is recorded for Replace/Remove

TopoDS_Shape Value (const TopoDS_Shape &shape) const
 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

virtual Standard_Integer Status (const TopoDS_Shape &shape, TopoDS_Shape &newsh, const Standard_Boolean last=Standard_False)
 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.

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

virtual TopoDS_Shape Apply (const TopoDS_Shape &shape, const TopAbs_ShapeEnum until=TopAbs_SHAPE)
 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.

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

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