Interface NodeAccess

All Superinterfaces:

PointAccess

All Known Implementing Classes:

ExtendedNodeAccess

public interface NodeAccess
extends PointAccess

This interface specifies how to access properties of the nodes in the graph. Similar to EdgeExplorer as it needs multiple instances for different threads or loops but without the need for an additional iterator.

Method Details

getTurnCostIndex

int getTurnCostIndex(int nodeId)

Returns:

the index used to retrieve turn cost information for this node, can be TurnCostStorage.NO_TURN_ENTRY in case no turn costs were stored for this node

Throws:

AssertionError - if, and only if, the underlying storage does not support turn costs

setTurnCostIndex

void setTurnCostIndex(int nodeId,
 int additionalValue)

Sets the turn cost index for this node, using TurnCostStorage.NO_TURN_ENTRY means there are no turn costs at this node.

Throws:

AssertionError - if, and only if, the underlying storage does not support turn costs
