Result <typename std::conditional< STD_IS_REPLACEMENT (same, T, 数据 ) || ( GetCollectionKind <T>::value == COLLECTION_KIND::ARRAY ), T, typename ByValueParam <T>::type>::type> Get ( ) const

Returns the value of type T of this 数据 . if <void> or <Data> is given the result value is not a reference.

Template Parameters
T The expected type of the value.
返回
The value stored in this 数据 , or an error if this 数据 doesn't store a value of type T.
