lachlan / Pipeline.java

Created June 26, 2012 23:33

What the webMethods Integration Server pipeline looks like as Java

	// Every webMethods Integration Server service has exactly one input
	// argument: the pipeline.
	//
	// The pipeline is like a java.util.Map object that gets passed to each
	// service that gets called. (It's actually a com.wm.data.IData object,
	// which unfortunately doesn't implement java.util.Map.)
	//
	// Because objects are passed by reference, every service called can alter
	// the keys and values in the pipeline.

What the webMethods Integration Server pipeline looks like as javascript

	// Every webMethods Integration Server service has exactly one input
	// argument: the pipeline.
	//
	// The pipeline is like a javascript object that gets passed to each
	// service that gets called. (It's actually a com.wm.data.IData object,
	// which is essentially a hash table.)
	//
	// Because objects are passed by reference, every service or function
	// called can alter the keys and values in the pipeline.
