the list of the Producers, this producer directly depends on
return this and the recursively reachable nodes in depth first, left first order Differs from transitiveDependencies in that this goes up both sides of an either and it returns the input node.
implicit conversion from Producer[P, T] to KeyedProducer[P, K, V] when the type T is a tuple of (K, V) as proven by evidence ev enabling the operations on keys (sumByKey, .
Returns true if this node does not directly change the data (does not apply any transformation)
returns true if this Producer is an output of the DAG (Summer and WrittenProducer)
The parents of the current node, possibly not its dependencies It differs from dependencies in that it will also return the predecessor of an AlsoProducer
Returns the first Summer of the provided list of Producers
a semigroup on producers where + means merge
A producer DAG starts from sources.
implicit conversion from Producer[P, (K, V)] to KeyedProducer[P, K, V] enabling the operations on keys (sumByKey, .
Return all dependencies of a given node in depth first, left first order.
