Method Detail

values

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

Returns:

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

valueOf

public static DefaultConsistencyLevel 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

getProtocolCode

public int getProtocolCode()

Description copied from interface: ConsistencyLevel

The numerical value that the level is encoded to in protocol frames.

Specified by:

getProtocolCode in interface ConsistencyLevel

fromCode

@NonNull
public static DefaultConsistencyLevel fromCode(int code)

isDcLocal

public boolean isDcLocal()

Description copied from interface: ConsistencyLevel

Whether this consistency level applies to the local datacenter only.

Specified by:

isDcLocal in interface ConsistencyLevel

isSerial

public boolean isSerial()

Description copied from interface: ConsistencyLevel

Whether this consistency level is serial, that is, applies only to the "paxos" phase of a lightweight transaction.

Serial consistency levels are only meaningful when executing conditional updates (INSERT, UPDATE or DELETE statements with an IF condition).

Specified by:

isSerial in interface ConsistencyLevel
