Package one.microstream.storage.types

Class EmbeddedStorage

java.lang.Object

one.microstream.storage.types.EmbeddedStorage

public final class EmbeddedStorage
extends Object

Static utility class containing static pseudo-constructor methods (indicated by a capital first letter) and various utility methods to setup and start a database.

In the simplest case, the following call is enough to setup and start an embedded object graph database:
EmbeddedStorageManager storage = EmbeddedStorage.start();
Anything beyond that is optimization and customization. As it should be.
