Enum RecoveryStrategy

java.lang.Object

java.lang.Enum<RecoveryStrategy>

io.github.bucket4j.grid.RecoveryStrategy

All Implemented Interfaces:

Serializable, Comparable<RecoveryStrategy>

public enum RecoveryStrategy
extends Enum<RecoveryStrategy>

Specifies the reaction which should be applied in case of previously saved state of bucket has been lost. The state of bucket can be lost by many reasons, for example:

• Split-brain happen.
• The bucket state was stored on single grid node without replication strategy and this node was crashed.
• Wrong cache configuration.
• Pragmatically errors introduced by vendor.
• Human mistake.

Each time when GridBucket detects that bucket state is missed, it applies this strategy to react.

Enum Constant Detail

RECONSTRUCT

public static final RecoveryStrategy RECONSTRUCT

Initialize bucket yet another time. Use this strategy if availability is more preferred than consistency.

THROW_BUCKET_NOT_FOUND_EXCEPTION

public static final RecoveryStrategy THROW_BUCKET_NOT_FOUND_EXCEPTION

Throw BucketNotFoundException. Use this strategy if consistency is more preferred than availability.

Method Detail

values

public static RecoveryStrategy[] 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 (RecoveryStrategy c : RecoveryStrategy.values())
    System.out.println(c);

Returns:

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

valueOf

public static RecoveryStrategy 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
