Loading Data

Loading data can be done in two ways, eager and Lazy. The basic, default way of loading is eager loading. This means that all objects of a stored object graph are loaded immediately. This is done during startup of the EclipseStore database instance automatically if an already existing database is found.

Contrary to lazy loading, eager loading has no requirements to your entity model.

To load your data you just need to create an EmbeddedStorageManager instance:

EmbeddedStorageManager storage = EmbeddedStorage.start();

After that just get the root instance of your object graph from the StorageManager by calling EmbeddedStorageManager.root() and check for null as this indicates a non-existing database

final EmbeddedStorageManager storage = EmbeddedStorage.start();

if(storage.root() == null)
{
	//No existing Database found
}
else
{
	MyRoot root = (MyRoot) storage.root();
}

The full code for the eager loading example is on GitHub.
