Class CellEntrance

java.lang.Object
  y.layout.router.polyline.CellEntrance

public class CellEntrance
extends Object

Describes where and from which direction a PartitionCell has been entered during a path search. The path to reach the cell can be reconstructed by traversing the previous entrances. The enter interval and enter direction determine how the cell was entered.

Constructor Summary

CellEntrance(CellEntrance other)
Creates a copy of the given CellEntrance.

CellEntrance(PartitionCell cell)
Creates a new instance.

Method Summary

PartitionCell	getCell() Returns this entrance's partition cell.
double	getCosts() Returns the costs for the implicit path given by the previous entrances.
Direction	getEnterDirection() Returns the direction from which this cell was entered.
OrthogonalInterval	getEnterInterval() Returns the OrthogonalInterval that was used to enter this cell.
EdgeCellInfo	getPreviousEdgeCellInfo() Returns the EdgeCellInfo describing how the previous cell was crossed.
CellEntrance	getPreviousEntrance() Returns the previous CellEntrance in the path that reached this cell.
void	setCosts(double costs) Sets the costs for the implicit path given by the previous entrances.
void	setEnterDirection(Direction direction) Sets the direction from which this cell was entered.
void	setEnterInterval(OrthogonalInterval interval) Sets the OrthogonalInterval that was used to enter this cell.
void	setPreviousEdgeCellInfo(EdgeCellInfo previousEdgeCellInfo) Sets the EdgeCellInfo describing how the previous cell was crossed.
