Description

Finds a TJSONValue object located at the specified APath JSON path, casts this JSON value as the T JSON type and fills AValue with the obtained JSON value. Returns True on success or False otherwise.

In the current version, TJSONValue implements the following functionality:

• If the specified APath is empty or it is not specified, TryGetValue casts this TJSONValue instance as the T type and fills AValue with the obtained JSON value. TryGetValue returns True if cast to T succeed.
• If not empty APath is specified, then TryGetValue returns False. AValue is not filled.
