StandardOperation#NEW operation. In Dynalink, Class objects
are not treated specially and act as ordinary Java objects; you can use e.g.
GET:PROPERTY:superclass as a property getter to
invoke clazz.getSuperclass(). On the other hand, you can not use
Class objects to access static members of a class, nor to create new
instances of the class using NEW. This is consistent with how
Class objects behave in Java: in Java, you write e.g.
new BitSet() instead of new BitSet.class(). Similarly, you
write System.out and not System.class.out. It is this aspect
of using a class name as the constructor and a namespace for static members
that StaticClass embodies.
Objects of this class are recognized by the BeansLinker as being
special, and operations on them will be linked against the represented class'
static members. The "class" synthetic property is additionally
recognized and returns the Java Class object, just as in Java
System.class evaluates to the Class object for the
System class. Conversely, Class objects exposed through
BeansLinker expose the "static" synthetic property which
returns their StaticClass object (there is no equivalent to this in
Java).
In summary, instances of this class act as namespaces for static members and as constructors for classes, much the same way as specifying a class name in Java language does, except that in Java this is just a syntactic element, while in Dynalink they are expressed as actual objects.
StaticClass objects representing Java array types will act as
constructors taking a single int argument and create an array of the
specified size.
If the class has several constructors, StandardOperation#NEW on
StaticClass will try to select the most specific applicable
constructor. You might want to expose a mechanism in your language for
selecting a constructor with an explicit signature through
BeansLinker#getConstructorMethod(Class, String).
