GetSlotNames(DataViewSchema+Column, VBuffer<ReadOnlyMemory<Char>>)	Stores the slots names of the input column into the provided buffer, if there are slot names. Otherwise it will throw an exception.
HasKeyValues(DataViewSchema+Column, PrimitiveDataViewType)	Returns true if the input column is of VectorDataViewType, and that has SlotNames annotation of a VectorDataViewType whose ItemType is of TextDataViewType, and further whose Size matches this input vector size.
HasSlotNames(DataViewSchema+Column)	Returns true if the input column is of VectorDataViewType, and that has SlotNames annotation of a VectorDataViewType whose ItemType is of TextDataViewType, and further whose Size matches this input vector size.
IsNormalized(DataViewSchema+Column)	Returns true if and only if column has IsNormalized annotation set to true.
