Method Detail

getEdge

public int getEdge()

Description copied from interface: RoutingCHEdgeIteratorState

The CH edge ID of this edge state. This is generally not the same as RoutingCHEdgeIteratorState.getOrigEdge()

Specified by:

getEdge in interface RoutingCHEdgeIteratorState

getOrigEdge

public int getOrigEdge()

Description copied from interface: RoutingCHEdgeIteratorState

The original/base/query graph edge ID of the edge this CH edge state represents or EdgeIterator.NO_EDGE if this is edge state is a shortcut

Specified by:

getOrigEdge in interface RoutingCHEdgeIteratorState

getOrigEdgeKeyFirst

public int getOrigEdgeKeyFirst()

Description copied from interface: RoutingCHEdgeIteratorState

For shortcuts of an edge-based CH graph this is the key of the first original edge of this edge state *in the direction of the shortcut*, i.e. the one this shortcut starts with. Otherwise it is the key of the original/base/query graph edge this CH edge state represents. It is not so obvious how the direction of this key shall be defined. For base graph edges it is clear as we use the storage direction and the value of the key simply depends on which node is the base node (the one stored first or second). For shortcut edges we use the direction of the shortcut to define the direction of the first/last original edge key.

Specified by:

getOrigEdgeKeyFirst in interface RoutingCHEdgeIteratorState

getOrigEdgeKeyLast

public int getOrigEdgeKeyLast()

Specified by:

getOrigEdgeKeyLast in interface RoutingCHEdgeIteratorState

See Also:

#getOrigEdgeKeyFirst(), but for the last edge, i.e. the one the shortcut points to. For shortcuts of an edge-based CH graph this is the key of the last original edge of this edge state, otherwise it is the key of the original/base/query graph edge this CH edge state represents.

getBaseNode

public int getBaseNode()

Specified by:

getBaseNode in interface RoutingCHEdgeIteratorState

getAdjNode

public int getAdjNode()

Specified by:

getAdjNode in interface RoutingCHEdgeIteratorState

isShortcut

public boolean isShortcut()

Specified by:

isShortcut in interface RoutingCHEdgeIteratorState

getSkippedEdge1

public int getSkippedEdge1()

Description copied from interface: RoutingCHEdgeIteratorState

The CH edge ID of the first skipped edge/shortcut of this edge state

Specified by:

getSkippedEdge1 in interface RoutingCHEdgeIteratorState

getSkippedEdge2

public int getSkippedEdge2()

Description copied from interface: RoutingCHEdgeIteratorState

The CH edge ID of the second skipped edge/shortcut of this edge state

Specified by:

getSkippedEdge2 in interface RoutingCHEdgeIteratorState

getWeight

public double getWeight(boolean reverse)

Specified by:

getWeight in interface RoutingCHEdgeIteratorState
