Typedef Documentation

typedef void* maps_route_segment_h

The Route Segment handle.

The handle of Route Segment instance.

Since :: 2.4

Remarks:: To release the handle use maps_route_segment_destroy().
To clone the handle use maps_route_segment_clone().

See also:: maps_route_segment_destroy(); maps_route_segment_clone()

typedef bool(* maps_route_segment_maneuver_cb)(int index, int total, maps_route_maneuver_h maneuver, void *user_data)

Called when requesting the Maneuvers of the Route Segment.

This callback is invoked while iterating through the list of Maneuvers, composing the Route Segment.

Since :: 2.4

Remarks:: Maneuver is valid only in this function and must be released using maps_route_maneuver_destroy().
To use Maneuver outside this function, clone it with maps_route_maneuver_clone().

Parameters:

[in]	index	The current index of Maneuvers list
[in]	total	The total amount of Maneuvers
[in]	maneuver	The Maneuver of route
[in]	user_data	The user data passed from maps_route_segment_foreach_maneuver()

Returns:: true to continue with the next iteration of the loop,
false to break out of the loop

Precondition:: maps_route_segment_foreach_maneuver() will invoke this callback.

See also:: maps_route_segment_foreach_maneuver(); maps_route_maneuver_h

typedef bool(* maps_route_segment_path_cb)(int index, int total, maps_coordinates_h coordinates, void *user_data)

Called when requesting the path of the Route Segment.

This callback is invoked while iterating through the list of coordinates, composing the Route Segment.

Since :: 2.4

Remarks:: coordinates must be released using maps_coordinates_destroy().
To use coordinates outside this function, clone it with maps_coordinates_clone().

Parameters:

[in]	index	The current index of coordinates list
[in]	total	The total amount of coordinates
[in]	coordinates	The current coordinates
[in]	user_data	The user data passed from maps_route_segment_foreach_path()

Returns:: true to continue with the next iteration of the loop,
false to break out of the loop

Precondition:: maps_route_segment_foreach_path() will invoke this callback.
