Enum Constant Detail

ANY

public static final ConsistencyLevel ANY

Ensure that the modification has been updated in at least 1 member before responding to the client, otherwise the modification is rejected and a ConsistencyLevelViolationException is thrown. In a primary backup topology that member is the primary.

QUORUM

public static final ConsistencyLevel QUORUM

Ensure that the modification has been updated in at least N / 2 + 1 members before responding to the client, otherwise the modification is rejected and a ConsistencyLevelViolationException is thrown. In a primary backup topology one of the members is the primary.

ALL

public static final ConsistencyLevel ALL

Ensure that the modification has been updated in all members before responding to the client, otherwise the modification is rejected and a ConsistencyLevelViolationException is thrown.

Method Detail

values

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

Returns:

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

valueOf

public static ConsistencyLevel 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
