As

out

earlier

on

this

page,
...
for
...
the

fluent
...
interface
...
to
...
work,
...
we
...
must
...
build
...
an
...
intermediate
...
representation
...
of
...
the
...
mixin
...
configuration
...
called
...
the
...
builder
...
.
...
Do
...
not
...
confuse
...
the
...
builder
...
for
...
the
...
mixin
...
configuration.
...
What
...
you
...
build
...
with

chained

methods

like

is
...
NOT
...
the
...
actual
...
mixin
...
configuration,
...
it
...
is
...
the
...
builder
...
,
...
an
...
intermediate
...
representation.
...
Each
...
method
...
like
...
ForClass<>
...
,
...
AddMixin<>
...
and
...
SuppressMixin
...
does
...
NOT
...
give
...
you
...
an
...
actual
...
configuration
...
item,
...
it
...
gives
...
you
...
some
...
object
...
that
...
represents
...
which
...
methods
...
you
...
have
...
piled
...
on
...
top
...
of
...
each
...
other
...
so
...
far.
...
It
...
is
...
the
...
final
...
BuildConfiguration
...
()
...
method
...
at
...
the
...
end
...
that
...
returns
...
the
...
actual
...
mixin
...
configuration
...
instance.
...
If
...
you
...
forget
...
that
...
BuildConfiguration
...
()
...
,
...
you
...
will
...
get
...
an

instance
...
of
...
the

wrong

type,
...
resulting

in

(at

time).
...
What's
...
more,
...
the
...
"Build"
...
in
...
BuildConfiguration
...
has
...
a
...
meaning
...
that
...
is
...
very
...
different

from

that

of

methods

like

BuildFromActive

BuildConfiguration ()is a method of an instance of the intermediate representation. It gives you the mixin configuration you have assembled one configuration item at a time.BuildEmpty ()is a static method of theMixinConfigurationclass and gives you an (empty, virgin, uninitialized) instance of the intermediate representation, ready for method chaining (= the fluent interface).- Along similiar lines,
BuildFromActiveis a method likeBuildEmpty (), only that it constructs an intermediate representation from the active configuration instead of an empty one.
