-------------------------------------
Summary: 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
Reporter: james strachan
Fix For: 2.11.5
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
