ColorDAG

class ColorDAG extends Error

The ColorDAG class provides a data structure Directed Acyclic Graphs (DAGs) with colored nodes. The ColorDAG consists of source nodes (in-degree is 0), sink nodes (out-degree is 0) and internal nodes. The edges connecting nodes must have color compatibility. The ColorDAG is divided into 'k' stages: e.g., sources (stage 0), internals (stages 1..k-2) and sinks (stage k-1).

  6. def checkIO(): Int

    For each node in the DAG, check that (1) all of its "inputs" are color/type compatible with an output from a node from the previous stage, and (2) at least one of its "outputs" is color/type compatible with an input to a node from the next stage.

    For each node in the DAG, check that (1) all of its "inputs" are color/type compatible with an output from a node from the previous stage, and (2) at least one of its "outputs" is color/type compatible with an input to a node from the next stage. Nodes that fails to have all of their inputs satified (check number 1) are thrown out before check if they have at least one useful output. Nodes failing check number 2 will also be thrown out.
