What's unclear about this method?
You can get a Type object that represents a typed-array, but there is
no way to create an instance of such an array. What good is it then
to get the Type object?

:-) So the whole concept is useless. Remind me why we
have parametric arrays?
Two uses currently: One is XMI serialization - it makes use of this
info for a much more compact serialized form.
The second: JCasGen uses this info when generating cover functions to do
compile-time checking of arguments, and returning the right class of
result. So, if you have an FSArray of Foo objects, defined as the
type:feature MyType:FooArray, the setters and getters for elements of
this type, anInstanceOfMyType.setFooArray(index, value) has the method
parameter type for "value" be of class Foo, rather than of class Top,
and anInstanceOfMyType.getFooArray(index) returns an instance of Foo class.
Perhaps there are other uses, but those come to mind right now. -Marshall
