Detailed Description

Base class for receivers of completion messages.

These receivers automatically reset, but cannot be explicitly waited on

Member Function Documentation

virtual task* tbb::flow::interface6::continue_receiver::execute

(

)

[protected, pure virtual]

Does whatever should happen when the threshold is reached.

This should be very fast or else spawn a task. This is called while the sender is blocked in the try_put().

bool tbb::flow::interface6::continue_receiver::remove_predecessor

(

predecessor_type &

)

[inline]

Decrements the trigger threshold.

Does not check to see if the removal of the predecessor now makes the current count exceed the new threshold. So removing a predecessor while the graph is active can cause unexpected results.
