Example for ApplicationComponent

ApplicationComponentsRestClient appCompsRestClient=Device42ClientFactory.createApplicationComponentsRestClient("https://example.device42.com","username","password");
                                                   
ApplicationComponentParameters.ApplicationComponentParametersBuilder appCompsParametersBuilder=new ApplicationComponentParameters.ApplicationComponentParametersBuilder();

ApplicationComponentParameters appCompsParameters=appCompsParametersBuilder.deviceId(2018l).build();
List<ApplicationComponent> list=appCompsRestClient.getApplicationComponents(appCompsParameters);

ApplicationComponent appComponent=new ApplicationComponent("app-name", "device-name");
appComponent.setJsonConfig("{\"config\":\"parameters\"}");

appCompsRestClient.createOrUpdateApplicationComponent(appComponent);
