Class Summary

Class	Description
AggregableCheckingOp<T>	A variant of IAggregableReduceOp exercised on a Writable that takes schema metadata in its constructor, and checks the input Writable against the schema before accepting it.
AggregableMultiOp<T>	This class transforms a list of IAggregableReduceOp on one single field, each returning a Writable and transforms it into an operation on that single column, that returns a Writable list.
AggregatorImpls	Created by huitseeker on 4/28/17.
AggregatorImpls.AggregableCount<T>
AggregatorImpls.AggregableCountUnique<T>	This distinct count is based on streamlib's implementation of "HyperLogLog in Practice: Algorithmic Engineering of a State of The Art Cardinality Estimation Algorithm", available here.
AggregatorImpls.AggregableFirst<T>
AggregatorImpls.AggregableLast<T>
AggregatorImpls.AggregableMax<T extends Number & Comparable<T>>
AggregatorImpls.AggregableMean<T extends Number>
AggregatorImpls.AggregableMin<T extends Number & Comparable<T>>
AggregatorImpls.AggregablePopulationVariance<T extends Number>	This class offers an aggregable reduce operation for the population variance, i.e.
AggregatorImpls.AggregableProd<T extends Number>
AggregatorImpls.AggregableRange<T extends Number & Comparable<T>>
AggregatorImpls.AggregableStdDev<T extends Number>	This class offers an aggregable reduce operation for the unbiased standard deviation, i.e.
AggregatorImpls.AggregableSum<T extends Number>
AggregatorImpls.AggregableUncorrectedStdDev<T extends Number>	This class offers an aggregable reduce operation for the biased standard deviation, i.e.
AggregatorImpls.AggregableVariance<T extends Number>	This class offers an aggregable reduce operation for the unbiased variance, i.e.
ByteWritableOp<T>	This class converts an IAggregableReduceOp operating on a Byte to one operating on Writable instances.
DispatchOp<T,U>	This class takes many IAggregableReduceOp, each acting on one field, and each returning several Writable elements, in the form of a list of Writable.
DispatchWithConditionOp<U>	A variant of DispatchOp that for each operation, tests the input list of elements for a Condition, before dispatching the appropriate column of this element to its operation.
DoubleWritableOp<T>	This class converts an IAggregableReduceOp operating on a Double to one operating on Writable instances.
FloatWritableOp<T>	This class converts an IAggregableReduceOp operating on a Float to one operating on Writable instances.
IntWritableOp<T>	This class converts an IAggregableReduceOp operating on a Integer to one operating on Writable instances.
LongWritableOp<T>	This class converts an IAggregableReduceOp operating on a Long to one operating on Writable instances.
StringAggregatorImpls	Groups useful IAggregableReduceOp utilities on Strings Created by huitseeker on 5/18/17.
StringAggregatorImpls.AggregableStringAppend
StringAggregatorImpls.AggregableStringPrepend
StringWritableOp<T>	This class converts an IAggregableReduceOp operating on a String to one operating on Writable instances.
