Method Detail

values

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

Returns:

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

valueOf

public static DefaultProtocolVersion 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:
