New Revision: 4493
URL: http://svn.boost.org/trac/boost/changeset/4493
Log:
This is a new example inspired in the task 9) a. That task is to write a new
unit test to check edge cases, in this case a class with six parameters. As
I was starting to write the new unit test I wondered that maybe I could
first write an example showing the multiple parameters functionality and
then test it.
- parameters: new directory containing the new test.
. main_lp: main function, creates the factory and constructs the
implementation.
. lots_of_parameters_interface.hpp: a dummy interface.
. lots_of_parameters.cpp: implementation of the interface with a
constructor with six parameters.
