transient lazy vals in constructor
I would like to declare a @transient lazy val as a constructor parameter. Example:
class Foo(@transient lazy val foo: FooFoo).
Scala 2.11 does not yet seem to have support for this. The suggested way in the issue linked above is to declare another lazy val as a class member, and have it point to the call-by-name constructor parameter.
Example (from the issue):
def f[a](lazy t: a) = {
..
}
should be equivalent to:
def f[a](t': => a) = {
lazy val t: a = t'
..
}
My question is: Will the second method ensure that the lazy val is correctly initialized upon deserialization on being referenced for the first time?
