JSON Support

Jactl has built-in support for JSON.

toJson​

The toJson method converts an object to a JSON string.

For example:

[a:1, b:[c:2]].toJson()            // {"a":1,"b":{"c":2}}

fromJson​

The fromJson method converts a JSON string to an object.

For example:

'{"a":1,"b":{"c":2}}'.fromJson()   // [a:1, b:[c:2]]

User Classes​

The JSON support also extends to user defined classes. Each class has a toJson() and a fromJson() generated for it.

toJson​

The toJson() function is an instance method, so to use it just invoke it on the object needed to be converted to JSON:

class X {
  int i = 123
  String s = 'abc'
}

def x = new X()
x.toJson()          // {"i":123,"s":"abc"}

fromJson​

The fromJson() method on a user defined class is a static method which is passed a string and returns a new instance of that class based on the contents of the string:

class X {
  int i = 123
  String s = 'abc'
}

X.fromJson('{"i":456,"s":"xyz"}')   // equivalent to new X(456, 'xyz')
