Enclosing class:

CollectionUtil

public static class CollectionUtil.ReduceException
extends RuntimeException

An exception wrapper for CollectionUtil.reduce(java.util.Collection<V>, net.sf.kdgcommons.collections.CollectionUtil.IndexValueReduceFunctor<V, R>). Contains the wrapped exception, the value and index that caused the exception, and the results-to-date.

Note: because Java does not allow parameterization of Throwable subclasses (JLS 8.1.2), the value and results are held as Objects.
