addressing various use cases:
</p>
<p>
+ <code>ConstantInitializer</code> is a very straightforward implementation
of
+ the <code>ConcurrentInitializer</code> interface: An instance is passed an
+ object when it is constructed. In its <code>get()</code> method it simply
+ returns this object. This is useful, for instance in unit tests or in
cases
+ when you want to pass a specific object to a component which expects a
+ <code>ConcurrentInitializer</code>.
+ </p>
+ <p>
The <code>LazyInitializer</code> class can be used to defer the creation
of
an object until it is actually used. This makes sense, for instance, if
the
creation of the object is expensive and would slow down application
startup
