<p>Les services en MAUI sont des classes instanci&#xE9;es une ou plusieurs fois et gard&#xE9;e en m&#xE9;moire, et qui peuvent &#xEA;tre r&#xE9;cup&#xE9;r&#xE9;es et utilis&#xE9;es par les <code>ViewModels</code> par l&apos;injection de d&#xE9;pendances.<br>

<p>Dans les applications <code>SicpaExpe</code> et <code>SIPMobile</code> on retrouve des services communs aux deux applications.</p>


    		
  

  

    
      285
    
    
      
<ul>


    		
  

  

    
      286
    
    
      
<li>Les services de DAO <code>ServerDAO</code> et <code>LocalDAO</code> qui contiennent les fonctions d&apos;acc&#xE8;s aux donn&#xE9;es sur les diff&#xE9;rentes bases (voir section sur WS REST).</li>


    		
  

  

    
      287
    
    
      
<li>Le <code>ConnexionService</code> qui g&#xE8;re l&apos;&#xE9;tat de la connexion.</li>


    		
  

  

    
      288
    
    
      
<li>Le <code>LoadingIndicatorService</code> qui permet de g&#xE9;rer l&apos;affichage de l&apos;indicateur de chargement. Permet de n&apos;avoir qu&apos;une seule classe qui g&#xE8;re la propri&#xE9;t&#xE9; <code>IsBusy</code> plutot que de l&apos;avoir dans chaque <code>ViewModel</code>. Permet aussi que des classes hors <code>ViewModels</code> puissent utiliser l&apos;indicateur de chargement.</li>


    		
  

  

    
      289
    
    
      
<li>Le <code>SettingsService</code> qui permet de garder quelques variables globales. Par exemple l&apos;unit&#xE9; actuelle dans l&apos;application <code>SIPMobile</code></li>


    		
  

  

    
      290
    
    
      
<li>Un service de gestion d&apos;envoi de donn&#xE9;es <code>MouvementService</code> sur <code>SIPMobile</code> et <code>DataSenderService</code> sur <code>SicpaExpe</code>. Cela permet de s&#xE9;parer et de factoriser les fonctions d&apos;envoi des donn&#xE9;es que je laissais auparavant dans les <code>ViewModels</code>.</li>


    		
  

  

    
      291
    
    
      
</ul>


    		
  

  

    
      292
    
    
      
<p>De plus, MAUI recommande que chaque <code>View</code> et chaque <code>ViewModel</code> soient aussi enregistr&#xE9;s en tant que service. Cela permet de profiter de <strong>l&apos;injection de d&#xE9;pendance</strong> en laissant l&apos;application instancier les classes avec les services dont elles ont besoin.</p>


    		
  

  

    
      293
    
    
      
<p>Chaque service doit &#xEA;tre enregistr&#xE9; dans le <code>MauiProgram</code>, point d&apos;entr&#xE9;e du code de l&apos;application. En &#xE9;tant enregistr&#xE9;, il peut ensuite &#xEA;tre inject&#xE9; dans chaque classe qui le demande.</p>

<p>Pour des souci de simplicit&#xE9; et pour &#xE9;viter les probl&#xE8;mes de d&#xE9;synchronisation je me suis fix&#xE9; les r&#xE8;gles de d&#xE9;veloppement suivantes :</p>


    		
  

  

    
      377
    
    
      
<ul>


    		
  

  

    
      378
    
    
      
<li>Toujours aller chercher les donn&#xE9;es dans la base de donn&#xE9;es locale SQLite</li>


    		
  

  

    
      379
    
    
      
<li>Minimiser le nombre d&apos;objets stock&#xE9;s comme variable globales</li>


    		
  

  

    
      380
    
    
      
<li>Synchroniser avec le serveur seulement lorsque la connexion est &#xE9;tablie</li>


    		
  

  

    
      381
    
    
      
</ul>


    		
  

  

    
      382
    
    
      
<p>Cela donne le workflow suivant lors de l&apos;enregistrement d&apos;un r&#xE9;sultat sur <code>SicpaExpe</code>, par exemple.</p>
