I have a few objects that have the same fields (referring to Article Types) such as: FAQ__kav, Tutorial__kav, Video__Kav



Is it possible to add all of these records to a single list (I guess of type Sobject) and then iterate over it? If so, what's the correct syntax?



Hoping to find something like this:



Faq__kav record1;
Tutorial__kav record2;
Video__kav record 3;

List<Sobject> kbList = new List<Sobject>();

kbliist.add(record1);
kblist.add(record2);

for(Sobject record : kbList){
 if(Sobject is type of FAQ__kav)
 do something...
 else if (Sobject is type of Tutorial__kav)
 do something else

You can use this dynamic access technique (all SObjects support map-like methods):



for (Sobject record : kbList) 
 String stringField = (String) record.get('StringFieldApiName');
 ...



to avoid the type-specific if/elseif/else coding for the common fields.



If you do need type-specific logic, the relatively new switch is a good way to do that:



for (Sobject record : kbList) 
 switch on record 
 when Faq__kav f 
 // f is a reference of type Faq__kav in this block
 
 when Tutorial__kav t 
 // t is a reference of type Tutorial__kav in this block
 
 when Video__kav v 
 // v is a reference of type Video__kav in this block

    @Json Yeah it's fairly new so you don't see many examples of it. Not sure if the class API version needs to be set to the latest or not - best to do that anyway if it is new code.

Confectionery

Prepared foods made with a lot of sugar or other cabohydrates "Sweetmeat" redirects here. For the racehorse, see Sweetmeat (horse). Not to be confused with Sweetbread. This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of ...
