Method Details

getReplyTo

public final @NonNull akka.actor.ActorRef getReplyTo()

addToStringAttributes

protected com.google.common.base.MoreObjects.ToStringHelper addToStringAttributes(com.google.common.base.MoreObjects.ToStringHelper toStringHelper)

Description copied from class: Message

Add attributes to the output of Message.toString(). Subclasses wanting to contribute additional information should override this method. Any null attributes will be omitted from the output.

Overrides:

addToStringAttributes in class Message<T extends org.opendaylight.yangtools.concepts.WritableIdentifier,C extends Request<T,C>>

Parameters:

toStringHelper - a MoreObjects.ToStringHelper instance

Returns:

The MoreObjects.ToStringHelper passed in as argument

externalizableProxy

protected abstract Request.SerialForm<T,C> externalizableProxy(ABIVersion version)

Description copied from class: Message

Instantiate a serialization proxy for this object for the target ABI version. Implementations should return different objects for incompatible ABIVersions. This method should never fail, as any compatibility checks should have been done by Message.cloneAsVersion(ABIVersion).

Specified by:

externalizableProxy in class Message<T extends org.opendaylight.yangtools.concepts.WritableIdentifier,C extends Request<T,C>>

Parameters:

version - Requested ABI version

Returns:

Proxy for this object
