zone.link.index
Syntax
- indexnext = zone.link.index(z,index)
Get the index of the next zone in the list of all zones connected to a gridpoint. This returns the next zone in the list of zones connected to the gripoint at index of this zone. Use the four intrinsics
gp.link.zone
,gp.link.index
,zone.link.zone
, andzone.link.index
to iterate through every zone connected to a gridpoint.Returns: indexnext - the index that the gridpoint has in the next zone in the list of all zones connected to that gridpoint
Arguments: z - a pointer to a zone
Usage Example
The following code fragment shows how to traverse all the zones connected to a single gridpoint.
local zone = gp.link.zone(gp)
local index = gp.link.index(gp)
loop while zone # null
(Do something with that zone)
local index_copy = zone.link.index(zone,index)
zone = zone.link.zone(zone,index)
index = index_copy
end_loop
