The type DataflowProcess contains the possible kinds of nodes that may appear in a dataflow process network. See type DataflowProcessNetwork for the dataflow process network itself. Note that Select and Switch nodes are used in a vector form, where the inputs/outputs y,x1,x0 and y1,y0,x are vectors of the same length n. Note that we do not use types for the data tokens, since we consider DPNs as an intermediate program representation like 3-address code. Hence, all tokens are bitvectors that may be interpreted as radix-2 or 2-complement numbers by the nodes.
