A map, each entry of which maps a Java

In addition to implementing <code>Map</code>, the additional type-safe operations
<A HREF="../../../../com/google/common/collect/ClassToInstanceMap.html#putInstance(java.lang.Class, T)"><CODE>putInstance(java.lang.Class<T>, T)</CODE></A> and <A HREF="../../../../com/google/common/collect/ClassToInstanceMap.html#getInstance(java.lang.Class)"><CODE>getInstance(java.lang.Class<T>)</CODE></A> are available.
<p>Like any other <code>Map&lt;Class, Object&gt;</code>, this map may contain entries
for primitive types, and a primitive type and its corresponding wrapper type
may map to different values.
