flow_control

flow_control#

[algorithms.parallel_pipeline.flow_control]

Enables the first filter in a composite filter to indicate when the end of input stream is reached.

Template function parallel_pipeline passes a flow_control object to the functor of the first filter. When the functor reaches the end of its input stream, it should invoke fc.stop() and return a dummy value that will not be passed to the next filter.
