deferred class CompositeClassifier from TopOpeBRepBuild
inherits LoopClassifier from TopOpeBRepBuild
---Purpose:
-- classify composite Loops, i.e, loops that can be either a Shape, or
-- a block of Elements.
uses
ShapeEnum from TopAbs,
Shape from TopoDS,
State from TopAbs,
Loop from TopOpeBRepBuild,
BlockBuilder from TopOpeBRepBuild
is
Initialize(BB : BlockBuilder);
Compare(me : in out; L1,L2 : Loop) returns State from TopAbs
is redefined;
CompareShapes(me : in out; B1,B2 : Shape from TopoDS)
---Purpose: classify shape <B1> with shape <B2>
returns State from TopAbs is deferred;
CompareElementToShape(me : in out; E,B : Shape from TopoDS)
---Purpose: classify element <E> with shape <B>
returns State from TopAbs is deferred;
ResetShape(me : in out; B : Shape from TopoDS) is deferred;
---Purpose: prepare classification involving shape <B>
-- calls ResetElement on first element of <B>
ResetElement(me : in out; E : Shape from TopoDS) is deferred;
---Purpose: prepare classification involving element <E>.
CompareElement(me : in out; E : Shape from TopoDS) is deferred;
---Purpose: Add element <E> in the set of elements used in classification.
State(me : in out) returns State from TopAbs is deferred;
---Purpose: Returns state of classification of 2D point, defined by
-- ResetElement, with the current set of elements, defined by Compare.
