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

(

)

const

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

Template Parameters

T	The expected type of the value.

Returns

The value stored in this Data, or an error if this Data doesn't store a value of type T.

Compares this object to a ConstDataPtr.

Parameters

c

Other object.

Returns

See COMPARERESULT.

Compares this object to a Data.

Parameters

c

Other object.

Returns

GetHashCode()

HashInt GetHashCode

(

)

const

Returns the hash code of the wrapped value. If the value's type doesn't provide a hash code function, this function returns DefaultHasher::EMPTY_HASH.

GetUniqueHashCode()

UniqueHash GetUniqueHashCode

(

)

const

Returns the hash code of the wrapped value. If the value's type doesn't provide a hash code function, this function returns a default-constructed UniqueHash.
