List of queueDeclarePassive() Examples

Examples of queueDeclarePassive()

com.rabbitmq.client.Channel.queueDeclarePassive()
Declare a queue passively; i.e., check if it exists. In AMQP 0-9-1, all arguments aside from nowait are ignored; and sending nowait makes this method a no-op, so we default it to false. @see com.rabbitmq.client.AMQP.Queue.Declare @see com.rabbitmq.client.AMQP.Queue.DeclareOk @param queue the name of the queue @return a declaration-confirm method to indicate the queue exists @throws java.io.IOException if an error is encountered,including if the queue does not exist and if the queue is exclusively owned by another connection.
