Java API - OServer

This class allows you to embed and manage a server instance within your application. Once you start the server, you can interact with it and manage data the same as you would standard instances of the OrientDB Server.

For more information, see Embedding the Server. For the complete OServer documentation, see the Javadocs.

Working with OServer

In order to operate on an OrientDB database, you first need to establish a connection with the server. You have two options in this: you can connect to a running OrientDB Server using OrientDB or you can embed the server within your application using this class. It can be found at com.orientechnologies.orient.server. For instance,

/* Import OrientDB Classes */
import com.orientechnologies.orient.server.OServer;

Once you've imported the class to your application, you can use one of the constructors to build a particular instance in your code.

Constructors

This class provides two constructors to create instances of OServer in your application. The first takes no arguments and the second takes a single boolean argument, which defines whether you want to shut the server down on exit.

// CONSTRUCTOR 1
OServer()

// CONSTRUCTOR 2
OServer(boolean shutdownEngineOnExit)
