Interface IBIInputReference
- All Superinterfaces:
- IBIIdentifiable, javax.jmi.reflect.RefBaseObject, javax.jmi.reflect.RefFeatured, javax.jmi.reflect.RefObject
- All Known Subinterfaces:
- IBIAddition, IBIAggregate, IBIAttributeReference, IBIAverage, IBIConcatenation, IBICount, IBIDivision, IBILiteralReference, IBIMaximum, IBIMedian, IBIMemberReference, IBIMinimum, IBIMultiplication, IBINumericValueFunction, IBIOperation, IBIRank, IBISignInversion, IBIStandardDeviation, IBISubtraction, IBISum, IBITupleReference, IBIVariance
- public interface IBIInputReference
- extends IBIIdentifiable
An adapter for plugging different types of objects as in-out parameters
into various expressions that are used in the OLAP Query Model. To illustrate,
the attribute expression of the IBISort
MemberSetExpression
is of the type IBIInputReference
. This reference yields the
sort criterion that is used for processing the sort operation. Of course,
different types of objects can serve as meaningful sort criteria, such
as the numeric value of a measure or the string value of a dimension attribute.
The advantage of this design is that the referenced objects are just referenced
by the adapter, but do not have to implement the adapter interface themselves.
There are three kinds of InputReferences
:
- Adapter classes, such as:
IBITupleReference
IBIMemberReference
IBIAttributeReference
IBILiteralReference
NumericValueFunctions
,
such as: IBIAggregate
IBIAverage
IBICount
Operations
,
such as: IBIAddition
IBISubtraction
IBIMultiplication
.
