rによって管理されているオブジェクトの株式を所有。 rに糸目を管理しない場合には、*thisもないオブジェクトを管理していません。 Y*T*に暗黙的に変換されていない場合は、テンプレート化されたオーバーロードオーバーロードの解決に参加しません。 shared_ptr<T> p(r).swap(*this)に相当.
Original:
Shares ownership of the object managed by r. If r manages no object, *this manages no object too. The templated overload doesn't participate in the overload resolution if Y* is not implicitly convertible to T*. Equivalent to shared_ptr<T> p(r).swap(*this).

Original:
Move-assigns a shared_ptr from r. After the assignment, *this contains a copy of the previous state of r, r is empty. The templated overload doesn't participate in the overload resolution if Y* is not implicitly convertible to T*. Equivalent to shared_ptr<T> p(std::move(r)).swap(*this).

Original:
Transfers the ownership of the object managed by r to *this. The deleter associated to r is stored for future deletion of the managed object. r manages no object after the call. Equivalent to shared_ptr<T> p(std::move(r)).swap(*this).
