com.ultikits.ultitools.interfaces.impl.data.json.JsonJournal.Entry

Enclosing class:

JsonJournal

static final class JsonJournal.Entry
extends Object

One change of a record: an entity file to write with its after-image, or to delete. The table name and the key are single path segments, so the entity file is always <identity root>/<table>/<key>.json and nothing is written outside that directory.
