Examples of org.mule.processor.AbstractRedeliveryPolicy

org.mule.processor.AbstractRedeliveryPolicy
Implement a redelivery policy for Mule. This is similar to JMS retry policies that will redeliver a message a maximum number of times. If this maximum is exceeded, the message is sent to a dead letter queue, Here, if the processing of the messages fails too often, the message is sent to the failedMessageProcessor MP, whence success is force to be returned, to allow the message to be considered "consumed".

        DefaultMessageProcessorChainBuilder requestChainBuilder = new EndpointMessageProcessorChainBuilder(endpoint, flowConstruct);
        requestChainBuilder.setName("InboundEndpoint '" + endpoint.getEndpointURI().getUri() + "' request chain");
        // Default MPs
        requestChainBuilder.chain(createInboundMessageProcessors(endpoint));
        // Configured MPs (if any)
        AbstractRedeliveryPolicy redeliveryPolicy = endpoint.getRedeliveryPolicy();
        if (redeliveryPolicy != null)
        {
            requestChainBuilder.chain(redeliveryPolicy);
        }
        requestChainBuilder.chain(endpoint.getMessageProcessors());
