Method Detail

getHost

public InetAddress getHost()

Description copied from interface: CoordinatorException

The coordinator host that was contacted.

This is a shortcut for getAddress().getAddress().

Specified by:

getHost in interface CoordinatorException

Returns:

The coordinator host that was contacted; may be null if the coordinator is not known.

getAddress

public InetSocketAddress getAddress()

Description copied from interface: CoordinatorException

The full address of the coordinator host that was contacted.

Specified by:

getAddress in interface CoordinatorException

Returns:

the full address of the coordinator host that was contacted; may be null if the coordinator is not known.

getServerVersion

public ProtocolVersion getServerVersion()

The version with which the server replied.

Note that this version is not necessarily a supported version. While this is usually the case, in rare situations, the server might respond with an unsupported version, to ensure that the client can decode its response properly. See CASSANDRA-11464 for more details.

Returns:

The version with which the server replied.

getUnsupportedVersion

public ProtocolVersion getUnsupportedVersion()

The version with which the client sent its request.

Returns:

The version with which the client sent its request.

copy

public UnsupportedProtocolVersionException copy()

Description copied from class: DriverException

Copy the exception.

This returns a new exception, equivalent to the original one, except that because a new object is created in the current thread, the top-most element in the stacktrace of the exception will refer to the current thread (this is mainly intended for internal use by the driver). The cause of the copied exception will be the original exception.

Overrides:

copy in class DriverException

Returns:

a copy/clone of this exception.
