Methodendetails

getAverage

double getAverage(Function<E,Number> valueMapper)

Parameter:

valueMapper -

Gibt zurück:

the average of the values the given valueMapper maps from the elements of the current AggregationRequestable. Maps null elements to 0.0.

Löst aus:

RuntimeException - if the given valueMapper is null.

RuntimeException - if the current AggregationRequestable is empty.

getAverageOrZero

double getAverageOrZero(Function<E,Number> valueMapper)

Parameter:

valueMapper -

Gibt zurück:

the average of the values the given valueMapper maps from the elements of the current AggregationRequestable if the current AggregationRequestable contains any, 0.0 otherwise. Maps null elements to 0.0.

Löst aus:

RuntimeException - if the given valueMapper is null.

getMax

<C extends Comparable<C>> C getMax(Function<E,C> comparableMapper)

Typparameter:

C - is the type of the Comparables the given comparableMapper maps from the elements of the current AggregationRequestable.

Parameter:

comparableMapper -

Gibt zurück:

the biggest Comparable the given comparableMapper maps from the elements of the current AggregationRequestable. Ignores null elements.

Löst aus:

RuntimeException - if the given comparableMapper is null.

RuntimeException - if the current AggregationRequestable does not contain a non-null element.

getMaxOrZero

double getMaxOrZero(Function<E,Number> numberMapper)

Parameter:

numberMapper -

Gibt zurück:

the biggest number the given numberMapper maps from the non-null elements of the current AggregationRequestable if the current AggregationRequestable contains non-null elements, 0.0 otherwise.

getMedian

double getMedian(Function<E,Number> numberMapper)

Parameter:

numberMapper -

Gibt zurück:

the median of the numbers the given numberMapper maps from the elements of the current AggregationRequestable. Maps null elements to 0.0.

Löst aus:

RuntimeException - if the given numberMapper is null.

RuntimeException - if the current AggregationRequestable is empty.

getMedianOrZero

double getMedianOrZero(Function<E,Number> numberMapper)

Parameter:

numberMapper -

Gibt zurück:

the median of the numbers the given numberMapper maps from the elements of the current AggregationRequestable if the current AggregationRequestable is not empty, 0.0 otherwise. Maps null elements to 0.0.

Löst aus:

RuntimeException - if the given numberMapper is null.

getMin

<C extends Comparable<C>> C getMin(Function<E,C> comparableMapper)

Typparameter:

C - is the type of the Comparables the given comparableMapper maps from the elements of the current AggregationRequestable.

Parameter:

comparableMapper -

Gibt zurück:

the smallest Comparable the given comparableMapper maps from the elements of the current AggregationRequestable. Ignores null elements.

Löst aus:

RuntimeException - if the given comparableMapper is null.

RuntimeException - if the current AggregationRequestable does not contain a non-null element.

getMinOrZero

double getMinOrZero(Function<E,Number> numberMapper)

Parameter:

numberMapper -

Gibt zurück:

the smallest number the given numberMapper maps from the non-null elements of the current AggregationRequestable if the current AggregationRequestable contains non-null elements, 0.0 otherwise.

getStandardDeviation

double getStandardDeviation(Function<E,Number> numberMapper)

Parameter:

numberMapper -

Gibt zurück:

the standard deviation of the numbers the given numberMapper maps from the elements of the current AggregationRequestable.

Löst aus:

RuntimeException - if the given numberMapper is null.

RuntimeException - if the current AggregationRequestable is empty.

getSum

BigDecimal getSum(Function<E,Number> valueMapper)

Parameter:

valueMapper -

Gibt zurück:

the sum of the values the given valueMapper maps from the elements of the current AggregationRequestable. Maps null elements to 0.0.

Löst aus:

RuntimeException - if the given valueMapper is null.

getSumOfInts

BigInteger getSumOfInts(ToIntFunction<E> intMapper)
