Method Detail

registerWith

public void registerWith(BoundedContext context)

isRegistered

public boolean isRegistered()

id

public java.lang.String id()

Obtains identity string of the dispatcher.

Default implementation returns fully-qualified name of the class.

Returns:

the string with the handler identity

producerId

public com.google.protobuf.Any producerId()

Obtains ID packed into Any for being used in generated events.

postEvents

protected void postEvents(java.lang.Iterable<io.spine.core.Event> events)

Posts passed events to EventBus.

onError

protected void onError(SignalEnvelope<?,?,?> signal,
                       io.spine.base.Error error)

onRejection

protected void onRejection(SignalEnvelope<?,?,?> signal,
                           io.spine.core.Event rejection)

equals

public boolean equals(java.lang.Object o)

Indicates whether some other command handler is "equal to" this one.

Two command handlers are equal if they handle the same set of commands.

Overrides:

equals in class java.lang.Object

Returns:

if the passed CommandHandler handles the same set of command classes
