Interface ITaskGraph<TV,TE>

All Known Implementing Classes:

BaseDataflowTaskGraph, ComputeGraph

public interface ITaskGraph<TV,TE>

This is the main interface for the task graph structure. A task graph 'TG' consists of set of Task Vertices 'TV' and Task Edges (TE) which is mathematically denoted as Task Graph (TG) -> (TV, TE).
