Detailed Description

This class represents the cost of traversing a link in the network. The default implementation of operator() simply return the length of the link augmented by any associated turn relation. Clients should provide derived classes in order to provide their own problem-specific cost definition.

◆ operator()()

virtual distance_type TSLOptPathCost::operator()	(	const TSLOptLink &	link,
		const TSLOptTurn &	turn,
		distance_type	cost ) const

virtual

Computes the cost of traversing the supplied link (incluing negotiating the turn).

Parameters

link	A reference to the current link.
turn	A reference to the associated turn.
cost	The current cost of getting to the link's source node.

Returns: the cost of traversing the link and negotiating the turn.
