Examples of com.persistit.Volume

com.persistit.Volume

Represent the identity and optionally the service classes that manage a volume. A newly constructed Volume is "hollow" in the sense that it has no ability to perform I/O on a backing file or allocate pages. In this state it represents the identity, but not the content, of the volume.

To enable the Volume to act on data, you must supply a {@link VolumeSpecification} object, either through the constructor or with{@link #setSpecification}, and then call the {@link #open(Persistit)} method.
