Yeah, LIKE I SAID, I know I can break out to a bean or a processor, but
that is such a heavyweight solution to do something so simple that really
should be built into Camel. You have to create a class, come up with some
meaningful name of the class, repeat that name a couple of times if using a
Spring DSL, etc.
Let's say we do it with anonymous classes in a Java DSL:
process(new Processor()
{
@Override
public void process(Exchange exchange) throws Exception
{
exchange.getIn().getBody(MyBodyType.class)
.setSomeProperty(exchange.getIn().getHeader("foo", SomeType.class);
}
})
Or perhaps better as a bean:
bean( new Object()
{
public void set( @Body MyBodyType body, @Header("foo") value)
{
body.setSomeProperty(value);
}
}
I personally would rather replace any of those with something more like
this in DSL:
body().set("someProperty", header("foo"))
This is much more obvious what is happening when looking at the route.
