java.lang.Enum<DurabilityLevel>

com.couchbase.client.core.msg.kv.DurabilityLevel

All Implemented Interfaces:

Serializable, Comparable<DurabilityLevel>

public enum DurabilityLevel
extends Enum<DurabilityLevel>

Specifies enhanced durability options for the mutation.

Enum Constant Summary

Enum Constants

Enum Constant	Description
MAJORITY	The mutation must be replicated to (that is, held in the memory allocated to the bucket on) a majority of the Data Service nodes.
MAJORITY_AND_PERSIST_TO_ACTIVE	The mutation must be replicated to a majority of the Data Service nodes.
NONE	No enhanced durability configured for the mutation.
PERSIST_TO_MAJORITY	The mutation must be persisted to a majority of the Data Service nodes.

Method Summary

Modifier and Type	Method	Description
byte	code()
static DurabilityLevel	valueOf(String name)	Returns the enum constant of this type with the specified name.
static DurabilityLevel[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

NONE

public static final DurabilityLevel NONE

No enhanced durability configured for the mutation.

MAJORITY

public static final DurabilityLevel MAJORITY

The mutation must be replicated to (that is, held in the memory allocated to the bucket on) a majority of the Data Service nodes.

MAJORITY_AND_PERSIST_TO_ACTIVE

public static final DurabilityLevel MAJORITY_AND_PERSIST_TO_ACTIVE

The mutation must be replicated to a majority of the Data Service nodes.

Additionally, it must be persisted (that is, written and synchronised to disk) on the node hosting the active partition (vBucket) for the data.

PERSIST_TO_MAJORITY

public static final DurabilityLevel PERSIST_TO_MAJORITY

The mutation must be persisted to a majority of the Data Service nodes.

Accordingly, it will be written to disk on those nodes.

Method Detail

values

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

Returns:

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

valueOf

public static DurabilityLevel 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
