• At ApacheCon Europe 2008 there was a Fast Feather talk that introduced some of the basic Scala language concepts that are being used for building the Scala DSL. Here are the presentation slides .

Enterprise integration patterns

Pipeline

There is a simple syntax available for specifying pipeline, by simple putting to or → between the different steps in the pipeline.

{snippet:id=simple|lang=java|url=activemq/camel/trunk/components/camel-scala/src/test/scala/org/apache/camel/scala/dsl/PipelineRouteBuilderTest.scala}

For more advanced use cases, you can also use a block-based syntax, where every step in the pipeline starts with either to or →.

{snippet:id=block|lang=java|url=activemq/camel/trunk/components/camel-scala/src/test/scala/org/apache/camel/scala/dsl/PipelineRouteBuilderTest.scala}
