Re: Question About Builder Object

To add to H.S.Lahman's response,

You can combine patterns as well. For example, if you want your concrete
builder to use a strategy to construct the object.

<calling-code>
MyBuildStrategy strat = MyBuildStrategy.StratFactory(); // see factory
method pattern
MyBuilder bld = MyBuilder.CreateBuilder( strat ); //
assign in the strategy to use by builder

MyTargetObject myobj = bld.CreateTargetObject(); // when
building the object, use the strategy.
</calling-code>

Of course, if the concrete builder has a one-to-one relationship with the
strategy, it is little more than a strategy itself, so the factory method
pattern will do with a strategy pattern under it. Depends on how you want
to isolate the dependencies.

    ... I don't own a copy of the Gang of Four book, so i can't check what they wrote, but i think they describe something that's a bit like the relationship between an XML parser and a DocumentFactory, where you have a Director that knows what steps have to be performed, and a Builder that knows how to execute the steps, and where the steps ultimately yield a complex Product of some sort. ... The other pattern, which i *think* might originate in a talk by Josh Bloch, is where a Builder is essentially a mutable, fairly passive holder for state that is then used to construct some Product in a single big-bang constructor invocation. ... public void addHeading; ... public Medal(MedalLevel level, Event event, String athlete, Nation nation) // ... ...
