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 JsValue
Represents 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
