Interface JsValue
-
- All Known Subinterfaces:
Json<T>
- All Known Implementing Classes:
JsArray,JsBigDec,JsBigInt,JsBinary,JsBool,JsDouble,JsInstant,JsInt,JsLong,JsNothing,JsNull,JsNumber,JsObj,JsPrimitive,JsStr
public interface JsValueRepresents a json element of any type. Every json type implements this interface. This interface implements two kind of methods:- Classificatory methods, which starts with the prefix isXXX
- Accessory methods to convert the JsValue to the real implementation, which starts with the prefix asJsXXX
