class WireEdgeClassifier from TopOpeBRepBuild
|
|
inherits CompositeClassifier from TopOpeBRepBuild
|
|
|
|
---Purpose:
|
|
-- Classify edges and wires.
|
|
-- shapes are Wires, Element are Edge.

|
|
---Purpose: prepare classification involving edge <E>
|
|
-- define 2D point (later used in Compare()) on first vertex of edge <E>.
|
|

|
CompareElement(me : in out; E : Shape from TopoDS);

|
---Purpose: Add the edge <E> in the set of edges used in 2D point
|
|
-- classification.
|
|
|
|
State(me : in out) returns State from TopAbs;
|
|
---Purpose: Returns state of classification of 2D point, defined by
|
|
-- ResetElement, with the current set of edges, defined by Compare.
