TypedLazy<T extends Object?> class abstract base

Base class for lazy evaluation of a typed value.

Same as Lazy, but with subsequent conversion of Object? to T using the convert method.

If the value already has type T, the convert method will not be called!

Important

When the value is converted, the original resolved object is released: after reading value, the resolved getter returns the converted value.
