## Diagrammes de séquence
- Envoi de demande d'ami :
```plantuml
actor User as u
boundary View as v
control Controller as c
entity Model as m

u->v:/Friend
v->c:Get : /Friends
c->m:getFriends(userId)
m-->c::friends : User[]
c-->v:renderView(Friends)
v-->u:
u->v:input : name
v->c:Get : searchFriends? pseudo=name
c->m:searchUser(name:string)
m->m:notify(from : user, to : user, action : action)
m-->c:OK
c-->v:OK
v-->u:OK
```
- Accepter une demande d'ami :
```plantuml
actor User as u
boundary View as v
control Controller as c
entity Model as m

m->c:RecevoirDemandeAmi(idUser)
c->v:AfficherDemandeAmi(idUser)
v->u:PageDemandeAmi(idUser)
u-->v:RepondreDemandeAmi(idUser)
v-->c:EnregistrerReponse(idUser)
c-->m:EnvoyerReponse(idUser)
```

- Supprimer un ami :

c->m: getFriends(userId)
alt successful retrieval
    m-->c: friendsList: User[]
else retrieval failed
    m-->c: error
