All Implemented Interfaces:

Output<DomainEventValue,T>, Receiver<UnitOfWorkDomainEventsValue,T>

public class EventRouter<T extends Throwable>
extends Object
implements Output<DomainEventValue,T>, Receiver<UnitOfWorkDomainEventsValue,T>

Event handling router. Add specification->receiver routes. When an event comes in the router will ask each specification if it matches, and if so, delegate to the receiver and return whether it successfully handled it or not. If no routes match, delegate to the default receiver

route

public EventRouter route(Specification<DomainEventValue> specification,
                         Receiver<DomainEventValue,T> receiver)

defaultReceiver

public EventRouter defaultReceiver(Receiver<DomainEventValue,T> defaultReceiver)

receiveFrom

public <SenderThrowableType extends Throwable> void receiveFrom(Sender<? extends DomainEventValue,SenderThrowableType> sender)
                 throws T extends Throwable,
                        SenderThrowableType extends Throwable

Description copied from interface: Output

This initiates a transfer from an Input. Implementations should open any resources to be written to and then call sender.sendTo() when it is ready to receive data. When sendTo() returns the resource should be closed properly. Make sure to handle any exceptions from sendTo.

Specified by:

receiveFrom in interface Output<DomainEventValue,T extends Throwable>

Type Parameters:

SenderThrowableType - the exception that sendTo can throw

Parameters:

sender - the sender of data to this output

Throws:

SenderThrowableType - the exception that the sender can throw

T extends Throwable

receive

public void receive(UnitOfWorkDomainEventsValue item)
             throws T extends Throwable

Description copied from interface: Receiver

Receive a single item of the given type. The receiver should process it and optionally throw an exception if it fails.

Specified by:

receive in interface Receiver<UnitOfWorkDomainEventsValue,T extends Throwable>

Throws:

T extends Throwable
