The examples in this section demonstrate calling a simple function named sum that takes two arguments, adds them, and returns the result:
exports = function(a, b) { return a + b;};To execute a function from the SDK, use the getFunctions() method of the your App to retrieve a Functions manager. Pass the name and parameters of the function you would like to call to callFunction() or callFunctionAsync():
String appID = YOUR_APP_ID; App app = new App(new AppConfiguration.Builder(appID).build());Credentials credentials = Credentials.anonymous();app.loginAsync(credentials, it -> { if (it.isSuccess()) { User user = app.currentUser(); assert user != null; Functions functionsManager = app.getFunctions(user); List<Integer> args = Arrays.asList(1, 2); functionsManager.callFunctionAsync("sum", args, Integer.class, result -> { if (result.isSuccess()) { Log.v("EXAMPLE", "Sum value: " + result.get()); } else { Log.e("EXAMPLE", "failed to call sum function with: " + result.getError()); } }); } else { Log.e("EXAMPLE", "Error logging into the Realm app. Make sure that anonymous authentication is enabled. Error: " + it.getError()); }});val appID = YOUR_APP_ID val app: App = App(AppConfiguration.Builder(appID).build())val anonymousCredentials: Credentials = Credentials.anonymous()app.loginAsync(anonymousCredentials) { if (it.isSuccess) { val user: User? = app.currentUser() val functionsManager: Functions = app.getFunctions(user) val args: List<Int> = listOf(1, 2) functionsManager.callFunctionAsync("sum", args, Integer::class.java) { result -> if (result.isSuccess) { Log.v("EXAMPLE", "Sum value: ${result.get()}") } else { Log.e("EXAMPLE", "failed to call sum function with: " + result.error) } } } else { Log.e("EXAMPLE", "Error logging into the Realm app. Make sure that anonymous authentication is enabled. Error: " + it.error) }}RetroSearch is an open source project built by @garambo | Open a GitHub Issue
