Usage

java

final String obj = "{\"key1\":1,\"key2\":\"abc\",\"key3\":[1,2,3]}";
final Map<String, ?> map = Parser.parse(obj);
assert Integer.valueOf(1).equals(map.get("key1"));
assert "abc".equals(map.get("key2"));
assert map.get("key3") instanceof List;

final String obj2 = Builder.build(map);
assert obj.equals(obj2);


final String arr = "[\"a\",1.5,{\"key\":\"value\"}]";
final List<?> list = Parser.parse(arr);
assert 3 == list.size();
assert "a".equals(list.get(0));
assert Double.valueOf(1.5).equals(list.get(1));
assert list.get(2) instanceof Map;

final String arr2 = Builder.build(list);
assert arr.equals(arr2);

groovy

String obj = '{"key1":1,"key2":"abc","key3":[1,2,3]}'
Map map = Parser.parse(obj)
assert 1 == map.key1
assert 'abc' == map.key2
assert map.key3 instanceof List
assert 3 == map.key3.size()
assert 1 == map.key3[0]
assert 2 == map.key3[1]
assert 3 == map.key3[2]

String obj2 = Builder.build(map)
assert obj == obj2
String obj3 = Builder.build([key1: 1, key2: 'abc', key3: [1, 2, 3]])
assert obj == obj3


String arr = '["a",1.5,{"key":"value"}]'
List list = Parser.parse(arr);
assert 3 == list.size();
assert "a" == list[0]
assert 1.5 == list[1]
assert list[2] instanceof Map
assert 'value' == list[2].key

String arr2 = Builder.build(list);
assert arr == arr2
String arr3 = Builder.build(['a', 1.5, [key: 'value']])
