do you mean something like "inject" function
<http://groovy.codehaus.org/groovy-jdk/java/util/Collection.html#inject(U,
groovy.lang.Closure)>in Groovy which is sending the result of one call to
the another or more like following "cumulate" method?
// some starter code
while(cursor.hasNext){
Pipes.cumulate(NextNode.class, cursor.next());
}
// next node class
NodeResult execute(ParallelPipe pipe, Entity en){
// count something based on the entity
pipe.join(TheFinalNode.class, count);
}
// the final node class
NodeResult execute(SerialPipe pipe, Collection<Long>){
// do something with the counts
}
