Classes in net.sf.jagg used by net.sf.jagg

AbstractCovarianceAggregator
This abstract class represents covariance-like aggregator calculations over numeric values.

AbstractVarianceAggregator
This abstract class represents variance-like aggregator calculations over numeric values.

AggregateValue
This class represents the result of a "group by" operation, where certain fields of a type are selected for a "group by", and certain values can be extracted by referring to Aggregators.

Aggregation
The Aggregation class performs the actual aggregation operations.

Aggregation.Builder
This Builder class follows the "Builder" pattern to create an Aggregation object.

Aggregator
This abstract class allows for the state necessary to implement aggregate functions.

AggregatorCache
Created as a wrapper around a HashMap that maps aggregator specification strings to Lists of Aggregators.

AvgAggregator
This class represents the "avg" aggregator over numeric values.

CollectAggregator
This class allows represents the "collect" aggregator over any values.

ConcatAggregator
This class represents the "concatenation" aggregator over any values for which toString is well-defined, with an optional separator String between values.

CorrelationAggregator
This class represents the "coefficient of correlation" aggregator over two sets of numeric values.

CountAggregator
This class represents the "count" aggregator over any values.

CovarianceAggregator
This class represents the "sample covariance" aggregator over two sets of numeric values.

CovariancePopAggregator
This class represents the "population covariance" aggregator over two sets of numeric values.

DoubleDouble
A DoubleDouble is used when extra precision is necessary to cut way down on floating point errors.

GeometricMeanAggregator
This class represents the "geometric mean" aggregator over numeric values.

HarmonicMeanAggregator
This class represents the "harmonic mean" aggregator over numeric values.

LinearRegressionAggregator
This class represents the "linear regression" aggregator over two sets of numeric values.

LinearRegressionStats
This class represents all statistics generated by a LinearRegressionAggregator.

MaxAggregator
This class represents the "max" aggregator over Comparable values.

MethodCache
Created as a wrapper around a HashMap that maps property names to Methods.

MethodCall
A MethodCall bundles a Method object and an array of parameter values together so they can go together into a Map as the value.

MinAggregator
This class represents the "min" aggregator over Comparable values.

ModeAggregator
This class represents the "mode" aggregator over Comparable values.

PercentileAggregator
This class allows represents the "percentile" aggregator over numeric values.

ProductAggregator
This class allows represents the "product" aggregator over numeric values.

PropertyScanner.Token
Enumeration for the different types of Tokens.

StdDevAggregator
This class represents the "sample standard deviation" aggregator over numeric values.

StdDevPopAggregator
This class represents the "population standard deviation" aggregator over numeric values.

SumAggregator
This class represents the "sum" aggregator over numeric values.

TwoPropAggregator
This abstract class allows for the state necessary to implement aggregate functions over two variables (properties).

VarianceAggregator
This class represents the "sample variance" aggregator over numeric values.

VariancePopAggregator
This class represents the "population variance" aggregator over numeric values.
