Class ContainerListOperations

java.lang.Object
org.rostore.v2.container.ContainerListOperations
All Implemented Interfaces:
AutoCloseable
public class ContainerListOperations extends Object implements AutoCloseable
This is the major class to manage the containers on the rostore.

Note that containers are optional components are are not stored on the Media per default.

If containers are required, this class should be created and made persisted on the media. For this the header stored on the media can be modified.

To create the containers on the media the ContainerListOperations(Media, ContainerListProperties) should be executed.

This method will create the ContainerListHeader, which should be persisted on the Media.

When the Media is opened, the ContainerListOperations can be recreated again if the stored ContainerListHeader is provided to the ContainerListOperations(Media, ContainerListHeader), which will reopen the containers in the form as they've been persisted.
