All Implemented Interfaces:

CoordinatorException, Serializable

public class ProtocolError
extends DriverInternalError
implements CoordinatorException

Indicates that the contacted host reported a protocol error. Protocol errors indicate that the client triggered a protocol violation (for instance, a QUERY message is sent before a STARTUP one has been sent). Protocol errors should be considered as a bug in the driver and reported as such.

Method Detail

getHost

public InetAddress getHost()

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()

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.

copy

public ProtocolError 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 DriverInternalError

Returns:

a copy/clone of this exception.
