Changeset 176 in pacpusframework for trunk/src/PacpusLib

Timestamp:

Oct 11, 2013, 2:10:06 PM (11 years ago)

Author:

Marek Kurdej

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.

Location:

trunk/src/PacpusLib

Files:

• ComponentBase.cpp (modified) (5 diffs)
• ComponentManager.cpp (modified) (1 diff)
• Log.cpp (modified) (2 diffs)
• XmlComponentConfig.cpp (modified) (2 diffs)
