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).

Method Summary

Modifier and Type	Method	Description
int	addHighway(Highway highway)	Add the specified highway to the highways collection.
Highway	getHighway(int identifier)	Returns the highway using the specified identifier.
Iterable<Highway>	getHighways()	Gets the highways iterator
int	getIdentifier(Highway highway)	Returns the identifier of the specified highway, or -1 if highways collection does not contain the element.
RoutePath	getPath(int idFrom, org.eclipse.draw2d.geometry.Point start, int idTo, org.eclipse.draw2d.geometry.Point end)	Finds the path
Highway	removeHighway(int identifier)	Removes the of the specified highway from highways collection.

Method Detail

getPath

RoutePath getPath(int idFrom,
                  org.eclipse.draw2d.geometry.Point start,
                  int idTo,
                  org.eclipse.draw2d.geometry.Point end)

Finds the path

Parameters:

idFrom - the identifier of the starting highway

start - the start point

idTo - the identifier of the ending highway

end - the end point and required direction from from this point

Returns:

finded path

Parameters:

highway - - the highway to be added to this matrix

Returns:

the identifier of the highway to be added

removeHighway

Highway removeHighway(int identifier)

Parameters:

identifier - - the identifier of the highway to be removed
