The
...
previous
...
pages
...
of
...
this
...
tutorial
...
cover
...
how
...
most
...
programmers
...
use
...
re-motion
...
mixins
...
most
...
of
...
the
...
time.
...
This
...
page
...
gives
...
you
...
some
...
background
...
information
...
and
...
shows
...
how
...
to
...
use
...
re-motion
...
mixins
...
dynamically
...
,
...
i.e.
...
how
...
to
...
mix
...
classes
...
at
...
run-time
...
in
...
an
...
ad-hoc
...
fashion.
...
Attributes
...
like
...
Uses
...
and
...
Extends
...
are
...
compiled
...
together
...
with
...
their
...
respective
...
target-
...
and
...
mixin
...
classes
...
and
...
show
...
up
...
in
...
the
...
executable
...
containing
...
the
...
resulting
...
.NET
...
IL
...
code.
...
When
...
the
...
re-motion
...
mixins
...
framework
...
starts
...
up,
...
usually
...
upon
...
first
...
use
...
of
...
ObjectFactory
...
,
...
it
...
inspects
...
the
...
executable
...
of
...
your
...
application
...
(=
...
your
...
code,
...
can
...
also
...
be
...
your
...
library)
...
and
...
builds
...
a
...
mixin
...
configuration
...
based
...
on
...
what
...
it
...
finds
...
in
...
your
...
executable.
...
This
...
configuration
...
is
...
a
...
representation
...
of
...
which
...
class
...
mixes
...
with
...
whom
...
and
...
becomes
...
the
...
master
...
configuration
...
during
...
the
...
initialization
...
of
...
re-motion
...
mixins
...
in
...
your
...
application
...
(or
...
library).
...
From
...
this
...
point
...
on,
...
each
...
thread
...
in
...
your
...
executable
...
will
...
get
...
a
...
reference
...
to
...
that
...
master
...
configuration,
...
so
...
that
...
a
...
call
...
to
...
the
...
object
...
factory
...
can
...
instantiate
...
mixed
...
classes
...
based
...
on
...
your
...
programming.
...
Here
...
is
...
an
...
illustration:
...
1.)
...
As
...
ParrotDemo.exe
...
starts
...
running,
...
it
...
initializes
...
re-motion
...
mixins
...
as
...
soon
...
as
...
the
...
ObjectFactory
...
is
...
used
...
for
...
the
...
first
...
time.
...
The
...
initialization
...
code
...
inspects
...
ParrotDemo.exe
...
and
...
builds
...
a
...
representation
...
of
...
all
...
the
...
target
...
classes,
...
mixin
...
classes
...
and
...
how
...
they
...
are
...
mixed.
...
This
...
representation
...
becomes
...
the
...
default
...
master
...
configuration
...
.
...
2.)
...
Each
...
thread
...
that
...
starts
...
up
...
gets
...
his
...
own
...
configuration
...
pointer
...
set
...
to
...
the
...
master
...
configuration
...
per
...
default.
...
This
...
configuration
...
is
...
the
...
thread's
...
active
...
configuration
...
.
...
Using
...
ObjectFactory
...
,
...
each
...
thread
...
can
...
now
...
instantiate
...
mixed
...
classes
...
to
...
its
...
heart's
...
content.
...
This
...
default
...
master
...
configuration
...
is
...
a
...
special
...
case
...
of
...
a
...
mixin
...
configuration.
...
Like
...
all
...
mixin
...
configurations,
...
it
...
is
...
an
...
instance
...
of
...
class
...
MixinConfiguration
...
.
...
However,
...
the
...
setup
...
illustrated
...
above
...
is
...
just
...
the
...
default
...
.
...
At
...
run-time
...
you
...
can
...
exert
...
much
...
more
...
control
...
over
...
mixin
...
configurations.
...
You
...
can
...
instantiate
...
and
...
construct
...
your
...
own
...
mixin
...
configurations
...
at
...
run-time,
...
even
...
give
...
each
...
thread
...
its
...
own
...
mixin
...
configuration
...
or
...
swap
...
in
...
and
...
out
...
particular
...
mixin
...
configurations
...
temporarily
...
in
...
a
...
thread.
...
Here
...
is
...
an
...
illustration
...
for
...
an
...
alternative
...
custom-setup
...
where
...
each
...
thread
...
points
...
to
...
its
...
own
...
mixin
...
configuration:
...
MixinConfiguration instances can't
...
be
...
modified
...
after
...
being
...
built.
...
In
...
order
...
to
...
create
...
another
...
mixin
...
configuration,
...
you
...
build
...
upon
...
an
...
existing
...
configuration,
...
add
...
configuration
...
items
...
to
...
it
...
(or
...
remove
...
configuration
...
items)
...
and
...
build
...
another
...
configuration
...
from
...
that.
...
If
...
you
...
want
...
to
...
go
...
all
...
the
...
way,
...
build
...
a
...
completely
...
new
...
configuration
...
and
...
add
...
configuration
...
items
...
to
...
that.
