class ShellFaceClassifier from BOP inherits CompositeClassifier from BOP
---Purpose:
--- The algorithm is to classify loops that
-- consist of faces and shells
---
uses
Shape from TopoDS,
Shell from TopoDS,
State from TopAbs,
Pnt from gp,
Builder from BRep,
BlockBuilder from BOP,
SolidClassifier from BOP,
DataMapOfShapeShape from TopTools
is
Create(theBlockBuilder: BlockBuilder from BOP)
returns ShellFaceClassifier from BOP;
---Purpose:
--- Creates a classifier in 3D space, to compare
--- a face with a set of faces,
--- a shell with a set of faces,
--- a shell with a shell
---
Clear(me: in out);
---Purpose:
--- Clears contents of internal state of the object
---
CompareShapes(me : in out;
B1 : Shape from TopoDS;
B2 : Shape from TopoDS)
returns State from TopAbs
is redefined;
---Purpose:
--- Classify shape <B1> with shape <B2>
---
CompareElementToShape(me : in out;
E : Shape from TopoDS;
B : Shape from TopoDS)
returns State from TopAbs
is redefined;
---Purpose:
--- Classify element <E> with shape <B>
---
ResetShape(me : in out;
B : Shape from TopoDS)
is redefined;
---Purpose:
--- Prepare classification involving shape <B>
--- Calls ResetElement on first element of <B>
---
ResetElement(me : in out;
E : Shape from TopoDS)
is redefined;
---Purpose:
--- Prepare classification involving element <E>.
---
CompareElement(me : in out;
E : Shape from TopoDS);
---Purpose:
--- Add element <E> in the set of elements used in classification.
---
State(me : in out)
returns State from TopAbs
is redefined;
---Purpose:
--- Returns state of classification of 2D point, defined by
--- ResetElement, with the current set of elements,
--- defined by Compare.
