def
addOption(name: String, expression: Any): Binding
Add a option to this container.
Add a option to this container.
This method inserts an option binding into the container. This binding is effectively the source of a options's value. Other steps may connect to this binding in order to read its computed value at runtime.
Option bindings consist of a name and an expression. The name and expression are arbitrary. At runtime the com.jafpl.runtime.ExpressionEvaluator provided as part of the com.jafpl.runtime.GraphRuntime must understand how to evaluate the expression.
Unlike a variable, an option value can be supplied at runtime which will be used *instead* of evaluating the expression.
At runtime, the computed values are provided to steps through binding edges.

dependsOn(node: Node): Unit
Add a dependency edge.
Add a dependency edge.
This method asserts that the current node depends on another node. Ordinarily, data flow establishes dependencies automatically. If step A consumes the output of step B, the pipeline will assure that step B runs before step A.
In cases where there is no data flow dependency, but it's still necessary to force an order, you can impose one by saying that
A.dependsOn(B).- node
The node in the graph which must be run before this one

Just Another Fine Pipeline Language
This is a pipeline framework. It’s built on top of Akka actors to support arbitrary data flow pipelines. It is wholly agnostic to the kinds of data that flow through the pipelines and the implementations of the steps that process them.
See http://jafpl.com/ for more general information.
