Instance Method Details

#inheritable_thread_local_var_get(var_name) ⇒ Object

NOTE: because there’s not a way to unset a thread variable, storing nil is used as deletion. this means that a thread local variable with nil can’t have any semantic meaning and should be treated the same as if #thread_variable? had returned false.
