Leo Neumeyer commented on S4-5:
-------------------------------
Great feedback, thanks!
* "onField" refers to the field name in the PE class that has a reference to a
target Stream array. That's why I call it onField. "onStream" seems to imply
the name of the stream which would be misleading. "onField" is not required
when there is no ambiguity. That is: all stream fields in the PE are
parametrized with different Event types. In that case the EDSL will figure out
what field to use. This is the best idea I came up with, if anyone has an
alternative, we can change. Perhaps we can call it "usePEField"?
* I will look into using a variable number of args for to()
* so you would use something like onStream(SomeStream.class,
SomeKeyFinder.class).usePEField("someField") [I don't think I can overload the
method so the optional "usePEField" method would have to be separate. What do
people think?
* edsl is a completely separate and optional project that depends on core but
core doesn't depend on edsl. This pattern will help create alternate UIs. So I
don't think we want UI code in core. The unit tests cases should be in the
examples or in edsl projects.
