Difference between AGSCodedValueDomain and AGSInheritedDomain

MuruganandhamKuppan1 — Mon, 14 May 2018 10:06:52 GMT

In my previous version, i have fetched the coded values from the domains property of 'AGSFeatureType'. In latest iOS Runtime SDK, the new subclass of AGSDomain, 'AGSInheritedDomain' has been added and no domains value founded.

#2. What is the difference between `AGSCodedValueDomain ` and AGSInheritedDomain

#3 Is there any way to get domain value form AGSInheritedDomain or to change the type from 'AGSInheritedDomain' to 'AGSCodedValueDomain'.

Hi Muruganandham Kuppan,

I need to find out more about the difference between the two, but this thread might be helpful to you.

Cheers,

Nick

Hi Nick,

Is there any way to avoid the "AGSInheritedCodedDomain" while creating subtypes.

Regards,

Hi Muruganandham,

If you're reading a subtype domain from an AGSFeatureType.domains and it's AGSInheritedDomain, you should look up the table's field (from which the domain will be inherited) with AGSArcGISFeatureTable.fieldForName() and read its domain property.

Note: The key to the AGSFeatureType.domains dictionary is the field name, so you can just pass that to AGSArcGISFeatureTable.fieldForName().

For example:

for featureType in table.featureTypes {
    guard let domains = featureType.domains else { continue }

    for (name,var domain) in domains {
        if domain is AGSInheritedDomain, let baseDomain = table.field(forName: name)?.domain {
            print("** \(name): Inherited Domain!")
            domain = baseDomain
        }
        // Now you've got the actual AGSCodedValueDomain or AGSRangeDomain…
    }
}

Sorry for the delayed response on this! Hope that helps.

Nick.
