Custom object renders for simple expression language?
I'm wondering if camel supports custom object renders (similar to log4j)
when doing the simple expression language? Currently it appears it just
calls toString() on the object
for example.
.log("Hello World ${body}");
Rather than calling ${body}.toString() I would like to have it call some
external bean that knows how to render the object.
For example
MyCustomRenderer implement ICamelObjectRenderer {
public String render(MyObject obj)
{
return obj.getName() + obj.getPhoneNumber();
}
}

Hi
You have a special use case where using something else than a
scripting language is better, such as a custom bean / processor. Or
implement your own language where you can extend another language if
you really wanna go down that path. Or take a look at what some of the
template libraries like freemarker, velocity can offer.
We should be careful not to add extensions / new functionality in
camel-core when just a single person has a special use-case.

Thanks. I've been using custom processors for a while however it adds a lot
of unnecessary code which would be nice to have built in.
Is it possible to submit feature requests or submit code that would provide
this capability?
Cheers

I'm afraid current Camel doesn't implement this feature.
If you want to render the object as you want, I suggest you to write a customer process for your object.
