Check Java Object Serialization Compatibility' title='Check Java Object Serialization Compatibility' />Minimalist JavaScript library for modern browsers with a largely jQuerycompatible API. The docs for java. Serializable are probably about as good an explanation as youll get The serialization runtime associates with each serializable class a version. MSDN Magazine Issues and Downloads. Read the magazine online, download a formatted digital version of each issue, or grab sample code and apps. CodeProject In a nutshell, serialization consists of writing data and objects on a support a file, a buffer, a socket, so that they can be reconstructed later in. This document describes the style guide, tag and image conventions we use in documentation comments for Java programs written at Java Software, Sun Microsystems.

We no longer support Eclipse as an IDE please migrate to Android Studio. Installation. Install Realm as a Gradle plugin. Step 1 Add the class path dependency to the project level build. Find the project level build. Step 2 Apply the realm android plugin to the top of the application level build. Find the application level build. Once you make these two changes, simply refresh your gradle dependencies. If youre upgrading from a version of Realm earlier than v. Find a sample of the two modified build. Enabling Realm Mobile Platform Before your application can synchronize with the Realm Object Server, it has to be enabled in your build file. Add this to the applications build. Enabledtrue Other Build Systems. The Maven Ant build systems are not supported. Were tracking interest in supporting them on Git. Hub A Pro.

You can also use the Stetho Realm plugin for Stetho, an Android debug bridge for the Chrome browser created by Facebook. Stetho Realm is not officially maintained by Realm. Examples. Take a look at our examples to see Realm used in practice in an app. See here for more details on how to run the examples. The intro. Example contains simple examples of how you use the Realm API. The grid. View. Example is a trivial app that shows how to use Realm as the backing store for a Grid. View. It also shows how you could populate the database with JSON using GSON plus how to use ABI splits to minimize the size of the final APK. The thread. Example is a simple app that shows how to use Realm in a multithreaded environment. The adapter. Example shows how to use the Realm. Base. Adapter and Realm. Recycler. View.

Example shows how you can write unit tests when working with Realm. The multi. Process. Example shows how to use Realm from different processes in the same APK. Initializing Realm. Before you can use Realm in your app, you must initialize it. This only has to be done once. Realm. initcontext You must provide an Android context. A good place to initialize Realm is in on.

A Realm is an instance of a Realm Mobile Database container. Realms can be local or synchronized. A synchronized Realm uses the Realm Object Server to transparently synchronize its contents with other devices. While your application continues working with a synchronized Realm as if its a local file, the data in that Realm might be updated by any device with write access to that Realm. In practice, your application works with any Realm, local or synchronized, the same way, although opening a synchronized Realm requires a User thats been authenticated to the Object Server and thats authorized to open that Realm. For a more detailed discussion about Realms, read The Realm Data Model. Opening Realms. Open a Realm by instantiating a new Realm object. Weve seen this used already in examples Initialize Realm.
