java.lang.Object
org.pipservices3.commons.convert.MapConverter
public class MapConverter extends Object
Converts arbitrary values into map objects. Converts using extended conversion rules:
  • Objects: property names as keys, property values as values
  • Arrays: element indexes as keys, elements as values

### Example ### 

 
 Map<String, Object> value1 = MapConverted.toNullableMap("ABC"); // Result: null
 Map<String, Object> value2 = MapConverted.toNullableMap({ key: 123 }); // Result: { key: 123 }
 Map<String, Object> value3 = MapConverted.toNullableMap(new int[]{1, 2, 3}); // Result: { "0": 1, "1": 2, "2": 3 }
