Cast

Feature Overview

This feature casts between different collections of lists, sets and maps.

Prerequisite

None

Sweet Apex Example

public class CastDemo {
    public static void main() {
        List list1 = (List => List)new List();

        Map map1 = (Map => Map)new Map();
    }
}
Transpiled Apex
public class CastDemo {
    public static void main() {
        List list1 = cast_Utils.cast_List_Object_to_List_String(new List());

        Map map1 = cast_Utils.cast_Map_Object_Object_to_Map_String_String(new Map());
    }
}

public class cast_Utils {
    
    public static List cast_List_Object_to_List_String(Object other) {
        List target = (List)other;
        List ret = new List();
        for(Object i : target) {
            String r = (String)i;
            ret.add(r);
        }

        return ret;
    }

    public static Map cast_Map_Object_Object_to_Map_String_String(Object other) {
        Map target = (Map)other;
        Map ret = new Map();
        for(Object key : target.keySet()) {
            Object value = target.get(key);
            String k = (String)key;
            String v = (String)value;
            ret.put(k, v);
        }

        return ret;
    }
}
Usage
An extra cast_Utils.cls will be generated to contain all the casting methods should it be used by other files.
Nested casting like (List> => List>) is also supported.
