|
* Routes commands based on typehints in the handler. |
|
12
|
|
|
* |
|
13
|
|
|
* If your handler has a public method with a single, non-scalar, no-interface type hinted |
|
14
|
|
|
* parameter, we'll assume that typehint is a command and route it to this |
|
15
|
|
|
* service definition as the handler. |
|
16
|
|
|
* |
|
17
|
|
|
* So, a class like this: |
|
18
|
|
|
* |
|
19
|
|
|
* class MyHandler |
|
20
|
|
|
* { |
|
21
|
|
|
* public function handle(RegisterUser $command) {...} |
|
22
|
|
|
* private function foobar(SomeObject $obj) {...} |
|
23
|
|
|
* public function checkThings(OtherObject $obj, WhatObject $obj2) |
|
24
|
|
|
* public function setADependency(ManagerInterface $interface) {...} |
|
25
|
|
|
* } |
|
26
|
|
|
* |
|
27
|
|
|
* would have RegisterUser routed to it, but not SomeObject (because it's |
|
28
|
|
|
* used in a private method), not OtherObject or WhatObject (because they |
|
29
|
|
|
* don't appear as the only parameter) and not setADependency (because it |
|
30
|
|
|
* has an interface type hinted parameter). |
