JSON Reader

Read values from JSON by specifying simple paths like 'a.b' or 'a.b[2].c'.

Examples

Basic usage:

String jsonString = '{"a": { "a2": "expected"} }';

Object result = new JsonReader(jsonString).read('a.a2');

System.assertEquals('expected', result);

With lists:

String jsonString = '{"a": { "a2": ["x", ["expected"]] } }';

Object result = new JsonReader(jsonString).read('a.a2[1][0]');

System.assertEquals('expected', result);

Specifying behaviour for missing keys:

String jsonString = '{"a": { "a2": "expected"} }';
final String NO_RESULT = 'no result';

Object result = new JsonReader(jsonString)
        .setMissingKeyResult(NO_RESULT)
        .read('a.nope');

System.assertEquals(NO_RESULT, result);
