| boolean edu::tum::cs::vis::model::util::Triangle::addNeighbor | ( | Triangle | neighbor, | |
| Lock | lock | |||
| ) | [inline] |
Add a neighbor to the neighbors list. If list contains already neighbor this method doesn't add it again. If not, the neighbor will be added and this instance will be added as a neighbor in the given neighbor instance.
| neighbor | neighbor to add. |
neighbor is really a neighbor of this triangle and it was successfully added. Definition at line 86 of file Triangle.java.
