Detailed Description

This class represents the cost of traversing a link in the network. The default implementation of operator() simply returns 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 TSLPathCost::operator()	(	const TSLLink &	link,
		const TSLTurn &	turn ) const

virtual

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

Parameters
