An `Invocation` message is a JSON object with the following properties:
|
||
|
|
|
||
|
|
* `type` - A `Number` with the literal value 1, indicating that this message
|
||
|
|
is an Invocation.
|
||
|
|
* `invocationId` - An optional `String` encoding the `Invocation ID`
|
||
|
|
for a message.
|
||
|
|
* `target` - A `String` encoding the `Target` name, as expected by the Callee's
|
||
|
|
Binder
|
||
|
|
* `arguments` - An `Array` containing arguments to apply to the method
|
||
|
|
referred to in Target. This is a sequence of JSON `Token`s,
|
||
|
|
encoded as indicated below in the "JSON Payload Encoding" section
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
```json
|
||
|
|
{
|
||
|
|
"type": 1,
|
||
|
|
"invocationId": "123",
|
||
|
|
"target": "Send",
|
||
|
|
"arguments": [
|
||
|
|
42,
|
||
|
|
"Test Message"
|
||
|
|
]
|
||
|
|
}
|
||
|
|
```
|
||
|
|
Example (Non-Blocking):
|
