Enum DseProtocolVersion

java.lang.Object

java.lang.Enum<DseProtocolVersion>

com.datastax.dse.driver.api.core.DseProtocolVersion

All Implemented Interfaces:

ProtocolVersion, Serializable, Comparable<DseProtocolVersion>

public enum DseProtocolVersion
extends Enum<DseProtocolVersion>
implements ProtocolVersion

A DSE-specific protocol version.

Legacy DSE versions did not have a specific version, but instead reused a Cassandra protocol version: DSE 5.0 is supported via DefaultProtocolVersion.V4, and DSE 4.7 and 4.8 via DefaultProtocolVersion.V3.

DSE 4.6 and earlier are not supported by this version of the driver, use the 1.x series.

Enum Constant Detail

DSE_V1

public static final DseProtocolVersion DSE_V1

Version 1, supported by DSE 5.1.0 and above.

DSE_V2

public static final DseProtocolVersion DSE_V2

Version 2, supported by DSE 6 and above.

Method Detail

values

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

Returns:

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

valueOf

public static DseProtocolVersion 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

getCode

public int getCode()

Description copied from interface: ProtocolVersion

A numeric code that uniquely identifies the version (this is the code used in network frames).

Specified by:

getCode in interface ProtocolVersion

isBeta

public boolean isBeta()

Description copied from interface: ProtocolVersion

Whether the protocol version is in a beta status.

Beta versions are intended for Cassandra development. They should not be used in a regular application, as beta features may break at any point.

Specified by:

isBeta in interface ProtocolVersion

supportsShardingInfo

public boolean supportsShardingInfo()

Description copied from interface: ProtocolVersion

Whether sharding info is supported in this protocol version

Specified by:

supportsShardingInfo in interface ProtocolVersion
