Unit functions cat_range

• cat_range(valuetype*, startvalue, endvalue)

* optional

cat_range(valuetype, startvalue, endvalue) sets the range for a categorical unit with arguments:

• valuetype, the optional value type for the configured unit
• startvalue, the lowest value of the allowed range
• endvalue, the highest value of the allowed range

The cat_range function configures a half open range. This means the value of argument: startvalue is the first value that is part of the range. Argument endvalue is the first value that falls outside the given range.

• It can also be used for two-dimensional domain units, grid domains, with a value type of the pointGroup;
• all arguments can be configured explicitly, but can also be the results of calculations.
• the startvalue argument can be different than the default value of 0.

• literal or parameter valuetype can be any value type.
• literals or parameters startvalue and endvalue of the configured valuetype argument

1. uint32 domain unit

unit<uint32> Province := cat_range(uint32, 1, 13)
{
   attribute<.> id := id(.);
}

Or shorter:

unit<uint32> Province := cat_range(1, 13)
{
   attribute<.> id := id(.);
}

domain Province, nr of rows = 12

2. spoint domain unit

unit<spoint> GridDomain := cat_range(spoint, point(10s, 14s), point(15s, 19s))
{ 
   attribute<.> id := id(.);
}

GridDomain/id, as rendered since GeoDMS 20.14.0 (before that: {10, 14} for the first cell, see XY-order)

GridDomain, nr of rows = 5, nr of cols = 5
