## 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::interface9::continue_receiver::execute | ( | ) |  |
| protectedpure 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().

Referenced by try_put_task().

bool tbb::flow::interface9::continue_receiver::remove_predecessor | ( | predecessor_type & | ) |  |
| inlinevirtual

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.

Reimplemented from tbb::flow::interface9::receiver< continue_msg >.
