Package com._1c.g5.v8.dt.common.gef.drow2d

Interface IHighwayMatrix

All Known Implementing Classes:
AbstractHighwayMatrix, HighwayMatrix, HighwayMatrixWave
public interface IHighwayMatrix
Search algorithm of a way from one highway to the another. Contains the collection of the highway. For fast access to this collection of ways identifiers are used.

Depending on implementation, can do intermediate calculations at the time of change of this collection (see addHighway(com._1c.g5.v8.dt.common.gef.drow2d.Highway) and removeHighway(int) methods).
