deferred class CompositeClassifier from BOP inherits LoopClassifier from BOP
---Purpose:
-- The Root class for algorithms
-- to 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 BOP,
BlockBuilder from BOP
is
Initialize(BB : BlockBuilder from BOP);
---Purpose:
--- Initializing the object with BlockBuilder;
---
Compare(me :out;
L1 : Loop from BOP;
L2 : Loop from BOP)
returns State from TopAbs
is redefined;
---Purpose:
--- Classify loop <L1> with <L2>
---
CompareShapes(me :out;
B1 : Shape from TopoDS;
B2 : Shape from TopoDS)
---Purpose:
--- Classify shape <B1> with shape <B2>
---
returns State from TopAbs
is deferred;
CompareElementToShape(me :out;
E : Shape from TopoDS;
B : Shape from TopoDS)
returns State from TopAbs
is deferred;
---Purpose:
--- Classify element <E> with shape <B>
---
ResetShape(me :out;
B : Shape from TopoDS)
is deferred;
---Purpose:
--- Prepare classification involving shape <B>
--- Calls ResetElement on first element of <B>
---
ResetElement(me :out;
E : Shape from TopoDS)
is deferred;
---Purpose:
--- Prepare classification involving element <E>.
---
CompareElement(me :out;
E : Shape from TopoDS)
is deferred;
---Purpose:
--- Add element <E> in the set of elements used in classification.
---
State(me :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.
