org.gytheio.messaging.benchmark.Bootstrap

public class Bootstrap
extends Object

Boostrap which creates an AmqpDirectEndpoint or Camel-based endpoint (depending on the brokerUrl given) with a BenchmarkConsumer to measure the throughput of a broker.

brokerUrl beginning with:

• tcp: creates a Camel-based endpoint using JSON object marshaling/unmarshaling
• amqp: creates an AmqpDirectEndpoint without object marshaling
