* Trait for client poolers. ClientPooler instances are factories for |

|
* Session's Client. The workflow of the ClientPooler is the following: |
20
|
|
|
* When a client is called |
21
|
|
|
* 1 It is fetched from the pool |
22
|
|
|
* 2.0 If no client is found: |
23
|
|
|
* 2.1 The createClient() method is triggered. |
24
|
|
|
* 2.2 The client is registered to the session |
25
|
|
|
* 3 The client is returned back |
