class ReShape from BRepTools inherits TShared from MMgt
---Purpose: 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
uses
ShapeEnum from TopAbs,
Shape from TopoDS,
DataMapOfShapeShape from TopTools
is
Create returns mutable ReShape from BRepTools;
---Purpose: Returns an empty Reshape
Clear (me: mutable);
---Purpose: Clears all substitutions requests
Remove (me: mutable; shape: Shape from TopoDS;
oriented: Boolean = Standard_False);
---Purpose: Sets a request to Remove a Shape
-- If <oriented> is True, only for a shape with the SAME
-- orientation. Else, whatever the orientation
Replace (me: mutable; shape, newshape: Shape from TopoDS;
oriented: Boolean = Standard_False);
---Purpose: 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
IsRecorded (me; shape: Shape from TopoDS) returns Boolean;
---Purpose: Tells if a shape is recorded for Replace/Remove
Value (me; shape: Shape from TopoDS) returns Shape from TopoDS;
---Purpose: 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
Status (me: mutable; shape: Shape from TopoDS; newsh: out Shape from TopoDS; last : Boolean = Standard_False)
returns Integer is virtual;
---Purpose: 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.
Apply (me: mutable; shape: Shape from TopoDS; until: ShapeEnum from TopAbs; buildmode: Integer)
returns Shape from TopoDS is virtual;
---Purpose: 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
Apply (me: mutable; shape: Shape from TopoDS; until: ShapeEnum from TopAbs = TopAbs_SHAPE)
returns Shape from TopoDS is virtual;
---Purpose: 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.
ModeConsiderLocation(me: mutable) returns Boolean;
---C++: return &
---Purpose:Returns (modifiable) the flag which defines whether Location of shape take into account
-- during replacing shapes.
ModeConsiderOrientation(me: mutable) returns Boolean;
---C++: return &
---Purpose:Returns (modifiable) the flag which defines whether Orientation of shape take into account
-- during replacing shapes.
