Enum JournalEntryType

java.lang.Object

java.lang.Enum<JournalEntryType>

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

All Implemented Interfaces:

Serializable, Comparable<JournalEntryType>

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

Method Detail

values

public static JournalEntryType[] values()

    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static JournalEntryType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
