christian ohr commented on CAMEL-7831:
--------------------------------------
It certainly does, except that you need this for *all* methods in
ProcessorDefinition taking an Expression as argument... Bloating the interface
just to add syntactic sugar feels cumbersome.
A function bridge could also be added to
ExpressionClause/ExpressionClauseSupport to be able to write:
{code}
from("direct:blorg")
.transform().function(exchange -> exchange.getProperty("some
prop"))
.to("direct:gablorg");
{code}
> create a java8 only demo showing how to use lambda expressions for Predicate
> / Expression inside the Java DSL (using Message as a typesafe parameter)

> Key: CAMEL-7831
> URL: https://issues.apache.org/jira/browse/CAMEL-7831
> Project: Camel
> Issue Type: New Feature
> Components: examples
> Reporter: james strachan
> Fix For: 2.18.0
>
>
> e.g. so folks can type things like
> {code}
> from("seda:cheese").
> filter(m -> m.getHeader("foo", int.class) > 5).
> map(m -> createPurchaseOrder(m.getBody(Invoice.class)).
> to("seda:bar");
> {code}
> Note if the current Predicate/Expression classes don't work as lambdas we
> could add a new interface with a single method to the DSL to ensure Java 8
> does the right thing with lambdas
