Author:

Message:

Added: addParameters() method in ComponentBase using Boost.Program_Options.
Each component can declare its parameters and they will be read automatically before configureComponent() method.
See example ProducerConsumerExample constructors.

• ConsumerExample.cpp (modified) (4 diffs)
• ConsumerExample.h (modified) (2 diffs)
