Detailed Description

Minimum required data for a node in the ClosedSet.

The ClosedSet is the set of routing nodes that have been already handled.

From the VNode list from the last routing node back to the start the route is recalculated by following the previousNode chain.

Some routing nodes may be accessed from two different ways

• one without any access restriction (!currentRestricted) and second with restriction (currentRestricted)

Restricted way (access=destination) is a way that may be used just in case when start or target is on this way (area of ways).

Constructor & Destructor Documentation

VNode() [1/2]

osmscout::RoutingService::VNode::VNode ( const DBId & currentNode, bool currentRestricted )

inlineexplicit

Simple constructor for searching for VNodes in the ClosedSet.

Parameters

currentNode

Offset of the node to search for

VNode() [2/2]

osmscout::RoutingService::VNode::VNode ( const DBId & currentNode, bool currentRestricted, const ObjectFileRef & object, const DBId & previousNode, bool previousRestricted )

inline

Full featured constructor

Parameters

currentNode	FileOffset of the current route node
object	Type of object used to navigate to this route node
previousNode	FileOffset of the previous route node visited

Member Function Documentation

operator==()

bool osmscout::RoutingService::VNode::operator== ( const VNode & other ) const

inline

Equality operator

Parameters

other

Other object to compare against

Returns

True, if both objects are equal. Objects are currently equal if they have the same route node file offset.

Member Data Documentation

currentNode

DBId osmscout::RoutingService::VNode::currentNode

FileOffset of this route node.

currentRestricted

bool osmscout::RoutingService::VNode::currentRestricted =false

Current node is accessed from restricted way.

object

ObjectFileRef osmscout::RoutingService::VNode::object

The object (way/area) visited from the current route node.

previousNode

DBId osmscout::RoutingService::VNode::previousNode

FileOffset of the previous route node.

previousRestricted

bool osmscout::RoutingService::VNode::previousRestricted =false

Previous node was accessed from restricted way.
