Method Detail

values

public static TraversalMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (TraversalMode c : TraversalMode.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static TraversalMode valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

createTraversalId

public final int createTraversalId(EdgeIteratorState edgeState,
                                   boolean reverse)

Returns the identifier to access the map of the shortest path tree according to the traversal mode. E.g. returning the adjacent node id in node-based behavior whilst returning the edge id in edge-based behavior

Parameters:

edgeState - the current EdgeIteratorState

reverse - true, if traversal in backward direction. Will be true only for backward searches in bidirectional algorithms.

Returns:

the identifier to access the shortest path tree

createTraversalId

public final int createTraversalId(RoutingCHEdgeIteratorState chEdgeState,
                                   boolean reverse)

isEdgeBased

public boolean isEdgeBased()
