Method Detail

getLinkCost

double getLinkCost(LODAnalysisInfo analysisInfo)

Computes the cost of the next link in the analysis info.

Parameters:

analysisInfo - analysis info

direction - direction the network is being searched, which can take the following two values: NetworkExplorer.DIRECTION_FORWARD or NetworkExplorer.DIRECTION_BACKWARD. Forward direction means that the network search direction is the same as the traveling direction, i.e., the traveling direction is from current node to next node. Backward direction means that the network search direction is the reverse of the traveling direction, i.e., the traveling direction is from next node to current node.

Returns:

link cost

getUserDataCategories

int[] getUserDataCategories()

Returns the required user data categories.

Returns:
