v3.0

Returns the size in bytes (as a Long) of the data attached to a particular component of the user data map.

This is equivalent to retrieving a UserDataItem with UserDataMap.Item and then using the UserDataItem.Size property.

Note: Since Python does not support input parameters on properties, this will fail in Python. Use the Python-compliant UserDataMap.GetItemSize2 method instead.
