| 7 | class EdgeStatus from HLRAlgo |
| 8 | |
| 9 | ---Purpose: This class describes the Hidden Line status of an |
| 10 | -- Edge. It contains : |
| 11 | -- |
| 12 | -- The Bounds of the Edge and their tolerances |
| 13 | -- |
| 14 | -- Two flags indicating if the edge is full visible |
| 15 | -- or full hidden. |
| 16 | -- |
| 17 | -- The Sequence of visible Intervals on the Edge. |
| 18 | |
| 19 | uses |
| 20 | Integer from Standard, |
| 21 | ShortReal from Standard, |
| 22 | Real from Standard, |
| 23 | Boolean from Standard, |
| 24 | Intervals from Intrv |

| 36 | returns EdgeStatus from HLRAlgo; |
| 37 | ---Purpose: Creates a new EdgeStatus. Default visible. The |
| 38 | -- Edge is bounded by the interval <Start>, <End> |
| 39 | -- with the tolerances <TolStart>, <TolEnd>. |

| 73 | OnBoundary : Boolean from Standard) |
| 74 | ---Purpose: Hides the interval <Start>, <End> with the |
| 75 | -- tolerances <TolStart>, <TolEnd>. This interval is |
| 76 | -- subtracted from the visible parts. If the hidden |
| 77 | -- part is on ( or under ) the face the flag <OnFace> |
| 78 | -- is True ( or False ). If the hidden part is on ( |
| 79 | -- or inside ) the boundary of the face the flag |
| 80 | -- <OnBoundary> is True ( or False ). |
