All Implemented Interfaces:

Calc, IterCalc, ListCalc

Enclosing class:

SetFunDef

public static class SetFunDef.SetListCalc
extends AbstractListCalc

Compiled expression to implement the MDX set function, { ... }, applied to a set of tuples, as a list.

The set function can contain expressions which yield sets together with expressions which yield individual tuples, provided that they all have the same type. It automatically removes null or partially-null tuples from the list.

Also, does not process high-cardinality dimensions specially.

SetListCalc

public SetListCalc(Exp exp,
                   Exp[] args,
                   ExpCompiler compiler,
                   List<ResultStyle> resultStyles)

Method Detail

getCalcs

public Calc[] getCalcs()

Description copied from class: AbstractCalc

Returns this expression's child expressions.

Overrides:

getCalcs in class AbstractCalc

evaluateList

public TupleList evaluateList(Evaluator evaluator)

Description copied from interface: ListCalc

Evaluates an expression to yield a list of tuples.

The list is immutable if Calc.getResultStyle() yields ResultStyle.MUTABLE_LIST. Otherwise, the caller must not modify the list.

Parameters:

evaluator - Evaluation context

Returns:

A list of tuples, never null.
