JSON > Parsing

There are several ways of creating JSON object from string:

1. Simply assign JSON string to THtJSON variable

var E: THtJSON := '{"some": "test"}';
ShowMessage(E.S['some']);

2. Implicit casting

var E := THtJSON('{"some": "test"}');

3. Parse method

var E: THtJSON;
E.Parse('{"some": "test"}');

4. Create method

var E := THtJSON.Create('{"some": "test"}');

5. LoadfromFile method:

var E: THtJSON;
E.LoadfromFile(FileName);

6. JSON() function.

Difference between Parse and Create is that Parse returns read-only object.

Simple values can be extracted from JSON without use of variables. Example:

sum := JSON(str).Find('result.orders[delivered=true].sum()');

To create a new empty object or array use Create('{}') or Create('[]')
