public interface Loader
In order for a Loader
implementation to successfully operate
with a Context
implementation that implements reloading, it
must obey the following constraints:
Lifecycle
so that the Context can indicate
that a new class loader is required.
start()
method must unconditionally create a new
ClassLoader
implementation.
stop()
method must throw away its reference to the
ClassLoader
previously utilized, so that the class loader,
all classes loaded by it, and all objects of those classes, can be
garbage collected.
stop()
to be followed by a call to
start()
on the same Loader
instance.
Context.reload()
method on the owning Context
when a change to one or more of the class files loaded by this class
loader is detected.
