get
Returns the value for the given class. If no value has yet been computed, it is obtained by an invocation of the .computeValue method.
The actual installation of the value on the class is performed atomically. At that point, if several racing threads have computed values, one is chosen, and returned to all the racing threads.
The type parameter is typically a class, but it may be any type, such as an interface, a primitive type (like int.class), or void.class.
In the absence of remove calls, a class value has a simple state diagram: uninitialized and initialized. When remove calls are made, the rules for value observation are more complex. See the documentation for .remove for more information.
Return
the current value associated with this ClassValue, for the given class or interface
Parameters
the type whose class value must be computed or retrieved
