scaleRoutes

public java.util.Map<com.here.android.mpa.routing.Route,java.lang.Float> scaleRoutes(java.util.Collection<com.here.android.mpa.routing.Route> routes)

Calculates the scale factors for the provided routes. The scale factors are relative to the longest duration of a route and can be used to scale the length of the SectionBar.

Parameters:

routes - the routes that should be compared to find the relative scale factor for each route.

Returns:

a map providing a scale factor for each route.

getScaling

public float getScaling(com.here.android.mpa.routing.Route input)

Gets the scale factor for the given route. Should be called after the relative scale factors for a collection of routes have been calculated.

Parameters:

input - the route

Returns:

the scale factor for the provided route or 1, if the scale factor was not calculated before.
