net.simplace.processors.ListReducerProcessor

Version: 1.0

This processor takes an array or java.util.Collection, java.util.SortedMap or java.util.LinkedHashMap as input and creates a java.util.LinkedHashMap which contains only a subset of the original data. The keys in the map correspond to the original indexes of remaining data.
Required input parameters:

Key sourceKey: key where to find the input data (array, java.util.Collection, java.util.SortedMap, java.util.LinkedHashMap).
Key outParamKey: Key where the output data (java.util.SortedMap is stored under. If not set the input key is overridden.
Key maxSize: Maximum number of elements the output map contains. The first element of the original data is always taken to the output data (unless maxSize > 1).
