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::interface7::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().

bool tbb::flow::interface7::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::interface7::receiver< continue_msg >.
