public abstract class AbstractInputData
extends java.lang.Object

Base class for algorithm input data classes. This class contains the basic data that are required by most graph algorithms, i.e. a graph, a mode (time / length) and a filter for the arc.

AbstractInputData

protected AbstractInputData(Graph graph,
                            ArcInspector arcInspector)

Create a new AbstractInputData instance for the given graph, mode and filter.

Parameters:

graph - Graph for this input data.

arcInspector - Arc inspector for this input data.

Method Detail

getGraph

public Graph getGraph()

Returns:

Graph associated with this input.

getCost

public double getCost(Arc arc)

Retrieve the cost associated with the given arc according to the underlying arc inspector.

Parameters:

arc - Arc for which cost should be retrieved.

Returns:

Cost for the given arc.

ArcInspector

getMode

public AbstractInputData.Mode getMode()

Returns:

Mode associated with this input data.

See Also:

AbstractInputData.Mode

getMaximumSpeed

public int getMaximumSpeed()

Retrieve the maximum speed associated with this input data, or GraphStatistics.NO_MAXIMUM_SPEED if none is associated. The maximum speed associated with input data is different from the maximum speed associated with graph (accessible via Graph.getGraphInformation()).

Returns:

The maximum speed for this inspector, or GraphStatistics.NO_MAXIMUM_SPEED if none is set.

isAllowed

public boolean isAllowed(Arc arc)

Check if the given arc is allowed for the filter corresponding to this input.

Parameters:

arc - Arc to check.

Returns:

true if the given arc is allowed.
