All Implemented Interfaces:

Serializable, Comparable<IStorePersister.StartupExpectation>

Enclosing interface:

IStorePersister

public static enum IStorePersister.StartupExpectation
extends Enum<IStorePersister.StartupExpectation>

Enumerates the set of supported startup expectations.

This enumerates the various startup expectations that can be requested when opening a persister. A startup expectation is an expectation of the state of the transaction log and/or it environment when the persister is starting up. A persister provided an expectation when starting will fail to start if the expectation is not met.

Enum Constant Detail

LogPresence

public static final IStorePersister.StartupExpectation LogPresence

Used to specify the expectation of the presence of the transaction log.

This value is used to specify the expectation of the presence of a persister's transaction log. Permissible values are enumerated by the log presence expectation enumeration i.e. IStorePersister.LogPresenceExpectation

LogEmptiness

public static final IStorePersister.StartupExpectation LogEmptiness

Used to specify the expectation of the emptiness of the transaction log.

This value is used to specify the expectation of the emptiness of a persister's transaction log. Permissible values are enumerated by the log emptiness expectation enumeration i.e. IStorePersister.LogEmptinessExpectation

Method Detail

values

public static IStorePersister.StartupExpectation[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (IStorePersister.StartupExpectation c : IStorePersister.StartupExpectation.values())
    System.out.println(c);

Returns:

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

valueOf

public static IStorePersister.StartupExpectation 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
