Enum Class JournalEntryType

java.lang.Object

java.lang.Enum<JournalEntryType>

org.apache.jena.dboe.transaction.txn.journal.JournalEntryType

All Implemented Interfaces:

Serializable, Comparable<JournalEntryType>, Constable

public enum JournalEntryType
extends Enum<JournalEntryType>

Types of Journal entry. This set is quite general and so not all cases may be used in practice.

The id must be stable across new versions on the code as it ends up in the journal on-disk so we are explicit about id even though there is Enum.ordinal
