map

public static <X> Function<@Nullable Object, X> map(String keyName,
 Type typeOfX)

Build a Command result mapper for the common case where the useful value is a single field of the response's result object.

The returned function is applied to a command's result value, which Connection has already parsed into a Map<String, Object>. It reads keyName from that map and deserializes it to typeOfX via Json.convert(Object, Type), without re-parsing any JSON text. Both the result and the field are required: a missing result or a null/absent field is an error.

Parameters:

keyName - the field to read from the command's result object

typeOfX - the type to deserialize that field to (class or TypeToken)
