Better support for Apache Camel InOut exchange pattern (Request-Reply)

[NickTheArchitect]

The Request Reply pattern is documented at http://camel.apache.org/request-reply.html. Note the following discussion about InOut pattern and using the in or out message: http://camel.apache.org/using-getin-or-getout-methods-on-exchange.html

Fix:

• Get the result of the Exchange from the Exchange's out message (to enable the InOut pattern) which will internally get the in message if the out isn't present

• Update the tests so that the first of the original tests uses a "real" Camel Exchange (with mock CamelContext), to show that the new call to send.getOut() works exactly like the original call to send.getIn() when there is no "out" message available.

• Add similar test which shows that an "out" message gets used if it exists.

• Fix the rest of the tests to "know" that getOut() is called instead of getIn().

Result My test code now has a Camel flavor ServiceTask like this (note the exchangePattern and the resultVariable): `

SequenceFlow_1skhzx5 SequenceFlow_159wdtm ` And the Camel route (in Groovy) looks like this: void configure() { from('direct:camelTestRoute') .routeId('direct:camelTestRoute') .log('Entering route') .process { Exchange exchange -> def body = exchange.in.body as Map // Use the "out" body with the value we want to return to become a process variable exchange.out.body = "Hello ${body.person} (but groovier)" } }
