This functions can be used to filter or collect specific nodes in collections
The Combine node type specifies the building of a CompNode as a result of applying an associative function to the values of an existing key-values CompNode
General methods for navigating a graph of CompNodes
generic functions for a nodes graph
The GroupByKey node type specifies the building of a CompNode as a result of partitioning an exiting key-value CompNode by key
The Load node type specifies the creation of a CompNode from some source other than another CompNode.
The Op node type specifies the building of Exp CompNode by applying a function to the values of two other CompNode nodes
Optimiser for the CompNode graph
The ParallelDo node type specifies the building of a CompNode as a result of applying a function to all elements of an existing CompNode and concatenating the results
Processing node in the computation graph.
The Return node type specifies the building of a Exp CompNode from an "ordinary" value.
This trait contains some display functions for computation graphs
Value node to either load or materialise a value
Value nodes have environments which are determined by the job configuration because they are effectively files which are distributed via the distributed cache
