Detailed Description

The graph class.

This class serves as a handle to the graph


Constructor & Destructor Documentation

tbb::flow::interface6::graph::~graph (  )  [inline]

Destroys the graph.

Calls wait_for_all on the graph, deletes all of the nodes appended by calls to add, and then destroys the root task of the graph.


Member Function Documentation

void tbb::flow::interface6::graph::decrement_wait_count (  )  [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.

void tbb::flow::interface6::graph::increment_wait_count (  )  [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.

template<typename Body>
void tbb::flow::interface6::graph::run ( Body  body  )  [inline]

Spawns a task that runs a function object.

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.

template<typename Receiver, typename Body>
void tbb::flow::interface6::graph::run ( Receiver &  r,
Body  body 
) [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.

void tbb::flow::interface6::graph::wait_for_all (  )  [inline]

Waits until the graph is idle and the number of decrement_wait_count calls equals the number of increment_wait_count calls.

The waiting thread will go off and steal work while it is block in the wait_for_all.
