```
public java.util.Map<ExpressionTuple,ReductionMapResult> getIndexedReductionMap(java.util.Set<ReductionTarget> sum,
 RecordSelector selector)
 throws java.lang.Exception
```
 Description copied from interface: ReductionProducer
 
 General reduction operation. The reduction is specified by a set of ReductionTarget objects. This method generates Maps from the requested ReductionTarget to the result of the corresponding reduction. If the list of ReductionTargets contains any IndexReduction objects then multiple results will be returned so these results are themselves returned as a Map indexed by PropertyTuple objects representing the Index values. If there are no IndexValues an empty PropertyTuple will be used. A non-index target that does not resolve may be ignored or return the default value for the ReductionTarget. This is so target set compatible with composite UsageProducers can contain targets only relevant to some of its parts without suppressing all output from the tables that don't support the property. This does run the risk that spurious index-tuples might be generated from tables that support none of the non-index targets. In that case the producer has to be tuned.
