|
48 * CIptvServiceManagementClient is the API object for IPTV Service database and Network Selection.\n |
|
49 * Application must implement virtual callback functions from MIptvServiceManagementClientObserver class.\n |
|
50 * |
|
51 * Instantiating of CIptvServiceManagementClient will start IPTV engine server if it is not running\n |
|
52 * already. |
|
53 * |
|
54 * Only one request pending per CIptvServiceManagementClient object is allowed simultaneously.\n |
|
55 * There is no protocol involved in calling functions. Any request may be called anytime assuming\n |
|
56 * that there is no other request pending already.\n |
|
57 * After service shutdown, client may not call any API functions anymore for that\n |
|
58 * CIptvServiceManagementClient object.\n |
|
59 * |
|
60 * Example:\n |
|
61 * |
|
62 * void CIptvClient::SomeFunc()\n |
|
63 * {\n |
|
64 * iIptvServiceManagementClient = CIptvServiceManagementClient::NewL(*this);\n |
|
65 * iIptvServiceManagementClient->GetAllServicesReq();\n |
|
66 * }\n |
|
67 * |
|
68 * void CIptvClient::GetAllServicesResp(MIptvServiceManagementClientObserver::TRespStatus aRespStatus,\n |
|
69 * CDesC16ArraySeg* aServicesArray)\n |
|
70 * {\n |
|
71 * |
|
72 * TInt i;\n |
|
73 * |
|
74 * CIptvService* iptvService;\n |
|
75 * iptvService = CIptvService::NewL();\n |
|
76 * CleanupStack::PushL(iptvService);\n |
|
77 * |
|
78 * for(i = 0; i < aServicesArray->MdcaCount(); i++)\n |
|
79 * {\n |
|
80 * iptvService->Set(aServicesArray->MdcaPoint(i));\n |
|
81 * RDebug::Print(_L("Service: %S"), &(iptvService->GetName()));\n |
|
82 * }\n |
|

84 * CleanupStack::PopAndDestroy(iptvService);\n |
