Public Member Functions | |
graph () | |
Constructs a graph with isolated task_group_context. | |
graph (task_group_context &use_this_context) | |
Constructs a graph with use_this_context as context. | |
~graph () | |
Destroys the graph. | |
void | increment_wait_count () |
Used to register that an external entity may still interact with the graph. | |
void | decrement_wait_count () |
Deregisters an external entity that may have interacted with the graph. | |
template<typename Receiver, typename Body> | |
void | run (Receiver &r, Body body) |
Spawns a task that runs a body and puts its output to a specific receiver. | |
template<typename Body> | |
void | run (Body body) |
Spawns a task that runs a function object. | |
void | wait_for_all () |
Wait until graph is idle and decrement_wait_count calls equals increment_wait_count calls. | |
task * | root_task () |
Returns the root task of the graph. | |

tbb::flow::interface6::graph::~graph | ( | ) | [inline] |
Destroys the graph.
Calls wait_for_all, then destroys the root task and context.
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.
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.
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] |
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.
