Class JSONParser

  • public class JSONParser
extends java.lang.Object
    A very small JSON parser. The JSON input is parsed into an object structure in the following way:
    • Object names are represented as a String.
    • String values are represented as a String.
    • Numeric values without a decimal separator are represented as a Long.
    • Numeric values with a decimal separator are represented as a Double.
    • Boolean values are represented as a Boolean.
    • Nested JSON objects are parsed into a Map<String, Object>.
    • JSON lists are parsed into a List which may contain any of the above values.
