----------------------------------
Summary: Support up-casting of Shared<T> and Owned<T>
Key: MESOS-6496
URL: https://issues.apache.org/jira/browse/MESOS-6496
Project: Mesos
Issue Type: Bug
Components: libprocess
Reporter: Neil Conway
It should be possible to pass a {{Shared<Derived>}} value to an object that
takes a parameter of type {{Shared<Base>}}. Similarly for {{Owned}}. In
general, {{Shared<T2>}} should be implicitly convertable to {{Shared<T1>}} iff
{{T2}} is implicitly convertable to {{T1}}. In C++11, this works because they
define the appropriate conversion constructor.
