Constructor Detail

GuavaEventBusEndpoint

public GuavaEventBusEndpoint(String endpointUri,
                             org.apache.camel.Component component,
                             com.google.common.eventbus.EventBus eventBus,
                             Class<?> listenerInterface)

Method Detail

createProducer

public org.apache.camel.Producer createProducer()
                                         throws Exception

Specified by:

createProducer in interface org.apache.camel.Endpoint

Throws:

Exception

createConsumer

public org.apache.camel.Consumer createConsumer(org.apache.camel.Processor processor)
                                         throws Exception

Specified by:

createConsumer in interface org.apache.camel.Endpoint

Throws:

Exception

isMultipleConsumersSupported

public boolean isMultipleConsumersSupported()

Specified by:

isMultipleConsumersSupported in interface org.apache.camel.MultipleConsumersSupport

getEventBusRef

public String getEventBusRef()

setEventBusRef

public void setEventBusRef(String eventBusRef)

To lookup the Guava EventBus from the registry with the given name

getEventBus

public com.google.common.eventbus.EventBus getEventBus()

setEventBus

public void setEventBus(com.google.common.eventbus.EventBus eventBus)

To use the given Guava EventBus instance

getEventClass

public Class<?> getEventClass()

setEventClass

public void setEventClass(Class<?> eventClass)

If used on the consumer side of the route, will filter events received from the EventBus to the instances of the class and superclasses of eventClass. Null value of this option is equal to setting it to the java.lang.Object i.e. the consumer will capture all messages incoming to the event bus. This option cannot be used together with listenerInterface option.

getListenerInterface

public Class<?> getListenerInterface()

setListenerInterface

public void setListenerInterface(Class<?> listenerInterface)

The interface with method(s) marked with the @Subscribe annotation. Dynamic proxy will be created over the interface so it could be registered as the EventBus listener. Particularly useful when creating multi-event listeners and for handling DeadEvent properly. This option cannot be used together with eventClass option.

doInit

protected void doInit()
               throws Exception

Overrides:

doInit in class org.apache.camel.support.DefaultEndpoint

Throws:

Exception
