Getting Started

To jump on the Xodus bandwagon, you’ll first define your project dependencies. Here’s how you can do that based on the build tool you’re using:

Using Maven

<dependency>
    <groupId>org.jetbrains.xodus</groupId>
    <artifactId>xodus-openAPI</artifactId>
    <version>2.0.1</version>
</dependency>

Using Gradle

dependencies {
    implementation("org.jetbrains.xodus:xodus-openAPI:2.0.1")
}

For detailed information on managing dependencies, refer to the Xodus documentation.

Understanding Xodus API Layers

Xodus operates using two main API layers: Environments and Entity Stores. Let’s break it down with an analogy!

Imagine you’re a librarian in a massive library:

• Environments are like different sections of the library where you manage books without mixing genres — this space ensures everything is organized as you put books in or take them out, maintaining your library’s integrity.
• Entity Stores are akin to individual book records where you can create, restore, or modify an entry, similar to writing in a book’s record whenever you make changes to it!

Implementing Environments

To work with environments, add the following dependency:

dependency
    groupId org.jetbrains.xodus
    artifactId xodus-environment
    version 2.0.1

Now you’re ready to use it!

try (Environment env = Environments.newInstance("home/me/myAppData")) {
    env.executeInTransaction(txn -> {
        final Store store = env.openStore("Messages", StoreConfig.WITHOUT_DUPLICATES, txn);
        store.put(txn, StringBinding.stringToEntry("Hello"), StringBinding.stringToEntry("World!"));
    });
}

Implementing Entity Stores

Adding support for entity stores involves the following dependencies:

dependencies {
    implementation("org.jetbrains.xodus:xodus-entity-store:2.0.1")
    implementation("org.jetbrains.xodus:xodus-environment:2.0.1")
    implementation("org.jetbrains.xodus:xodus-vfs:2.0.1")
}

Now let’s see how to utilize it:

try (PersistentEntityStore entityStore = PersistentEntityStores.newInstance("home/me/myAppData")) {
    entityStore.executeInTransaction(txn -> {
        final Entity message = txn.newEntity("Message");
        message.setProperty("hello", "World!");
    });
}

Building from Source

To get started with building Xodus, ensure you have Gradle and JDK 1.8 or higher. Run the following command:

./gradlew build

If you would like to build without executing tests, simply adjust your command as follows:

./gradlew assemble
