The graph class.
This class serves as a handle to the graph
|
inline |
Destroys the graph.
Calls wait_for_all, then destroys the root task and context.
|
inline |
Deregisters an external entity that may have interacted with the graph.
The graph will not return from wait_for_all until all the number of decrement_wait_count calls matches the number of increment_wait_count calls.
|
inline |
Used to register that an external entity may still interact with the graph.
The graph will not return from wait_for_all until a matching number of decrement_wait_count calls is made.
|
inline |
Spawns a task that runs a body and puts its output to a specific receiver.
The task is spawned as a child of the graph. This is useful for running tasks that need to block a wait_for_all() on the graph. For example a one-off source.

Wait until graph is idle and decrement_wait_count calls equals increment_wait_count calls.
The waiting thread will go off and steal work while it is block in the wait_for_all.
