TJSONData is an abstract class which introduces all properties and methods needed to work with JSON-based data. It should never be instantiated. Based on the type of data that must be represented one of the following descendents must be instantiated instead.
|
Class to represent 32-bit integer JSON data. |
|
|
Class to represent string JSON data. |
|
|
Class to represent boolean JSON data. |
|
|
Class to represent boolean JSON data. |
|
|
Class of TJSONArray |
