Member Function Documentation

◆ acquire_services()

void JTopologyBuilder::acquire_services ( JServiceLocator * sl )

overridevirtual

Reimplemented from JService.

◆ set_configure_fn()

void JTopologyBuilder::set_configure_fn ( std::function< void(JTopologyBuilder &)> configure_fn )

set_cofigure_fn lets the user provide a lambda that sets up a topology after all components have been loaded.

It provides an 'empty' JArrowTopology which has been furnished with a pointer to the JComponentManager, the JEventPool, and the JProcessorMapping (in case you care about NUMA details). However, it does not contain any queues or arrows. You have to furnish those yourself.

The documentation for this class was generated from the following files:

JTopologyBuilder.h
JTopologyBuilder.cc
