Method Detail

getReplyTo

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

Return the return address where responses to this request should be directed to.

Returns:

Original requestor

toRequestFailure

@Nonnull
public abstract RequestFailure<T,?> toRequestFailure(@Nonnull
                                                              RequestException cause)

Return a RequestFailure for this request, caused by a RequestException.

Parameters:

cause - Failure cause

Returns:

RequestFailure corresponding to this request

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 AbstractRequestProxy<T,C> externalizableProxy(@Nonnull
                                                                 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).

Parameters:

version - Requested ABI version

Returns:

Proxy for this object
