Examples of com.rabbitmq.client.Consumer

com.rabbitmq.client.Consumer
Interface for application callback objects to receive notifications and messages from a queue by subscription. Most implementations will subclass {@link DefaultConsumer}.
The methods of this interface are invoked in a dispatch thread which is separate from the {@link Connection}'s thread. This allows {@link Consumer}s to call {@link Channel} or {@link Connection} methods without causing a deadlock.
The {@link Consumer}s on a particular {@link Channel} are invoked serially on one or moredispatch threads. {@link Consumer}s should avoid executing long-running code because this will delay dispatch of messages to other {@link Consumer}s on the same {@link Channel}. @see Channel#basicConsume(String,boolean,String,boolean,boolean,java.util.Map,Consumer) @see Channel#basicCancel
