Interface Alias
- public interface Alias
- extends DataSet
This describes the API for a Data Set Alias.
An Alias is a way of creating a secondary named view of a Data Set.
This is useful when you need to have 2 full views of the same data.
For example, imagine sheet bursting by the 'state' field in some
data set named 'A'. Then within a MatrixRange on each bursted
'state' sheet, you want to show how a 'state' total relates to
the total of all states. The total of all states requires looking
at all of the data. Since 'A' is being used to burst,
'A' only has the results for the current state. To do this you could
create an Alias 'B' for query 'A'. Alias 'B' is not affected by the
sheet bursting and so still has data for all of the states, so 'B' can
be used to calculate a total for all of the states.
