For further examples of this pattern in use you could look at one of the junit test case
Parallel execution of distinct 'parts'
If you want to execute all parts in parallel you can use special notation of splitter() with two arguments, where the second one is a flag if processing should be parallel. e.g.
XPathBuilder xPathBuilder = new XPathBuilder("//foo/bar");
Using This Pattern
If you would like to use this EIP Pattern then please read the Getting Started, you may also find the Architecture useful particularly the description of Endpoint and URIs. Then you could try out some of the Examples first before trying this pattern out.
