Introduction

The grid service manages information about regions on the grid.

API

Functions available on the grid service are

• register - registers a region with the grid.
• deregister - deregisters a region from the grid.
• get_neighbours - gets the region neighbours of a given location.
• get_region_by_uuid - returns region details given a region UUID.
• get_region_by_position - returns region details given a position.
• get_region_by_name - returns region details given a name. This will only return the first name if there are multiple regions with the same name.
• get_regions_by_name - returns details of all regions that match a given name
• get_region_range - returns details of all regions in a given area
• get_default_regions - returns default regions for a grid. These are regions that are tried in order if the requested login region does not exist.
• get_default_hypergrid_regions - returns default Hypergrid regions for a grid. These are regions that are tried in order if Hypergrid destination request by an inbound foreign user does not exist.
• get_fallback_regions - returns fallback regions for a grid. These are regions that are tried in order if no default regions are online.
• get_hyperlinks - get linked Hypergrid regions.
• get_region_flags - get flags for a region.

get_region_range

This gets information on all the regions in a given co-ordinate range.

The POST field is a urlencoded string like so

SCOPEID=00000000-0000-0000-0000-000000000000&XMIN=0&YMIN=0&XMAX=2147483647&YMAX=2147483647&METHOD=get_region_range 

where

• SCOPEID must always be present and always 00000000-0000-0000-0000-000000000000 (UUID.Zero) at the present time.
• XMIN The minimum x-coordinate in the region range. Please note that this is in meters, not 256m map tiles. So to start this at map tile co-ordinate 1000, one must specify 256000 (1000 * 256).
• YMIN The minimum u-coordinate in the region range. Please note that this is in meters, not 256m map tiles.
• XMAX The maximum x-coordinate in the region range. Please note that this is in meters, not 256m map tiles.
• XMIN The maximum y-coordinate in the region range. Please note that this is in meters, not 256m map tiles.

If there are any regions in the range, a response like

<?xml version="1.0"?>
<ServerResponse>
  <region0 type="List">

If no matching regions are found then

<?xml version="1.0"?>
<ServerResponse>
  <result>null</result>
</ServerResponse>

will be returned.
