semipipelinesplitter.h
|
|
|
|
A connection manager which looks almost like a pipelinesplitter.
|
|
However, the vertices may have inputs coming from other stages as
|
|
well. These inputs are replicated instead of creating additional
|
|
copies.
|
|
|
|
I.e.
|
|
|
|
(A >= B) || (C >= B) || (A >= C)
|
|
|
|
The (A >= C) edge is required so that C does not yet execute when B is being rewritten.
|
|
With a semipipelinesplitter on the edge (A >= B) the following occurs:
|
|
|
|
When A is expanded to (A,A,A) the graph becomes:
|
|
|
|
(A,A,A) >= (B,B,B) || C >= (B,B,B) || (A,A,A) => C
|
|
|
|
The simple pipelinesplitter does not handle the C => (B,B,B) connection.
