Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface StatisticResult
extends java.util.function.DoubleSupplier, java.util.function.IntSupplier, java.util.function.LongSupplier

Represents the result of a statistic computed over a set of values.

Base interface implemented by all statistics.

Methods inherited from interface java.util.function.DoubleSupplier

getAsDouble

Method Detail

getAsInt

default int getAsInt()

The default implementation uses the closest representable int value of the DoubleSupplier.getAsDouble() result. In the event of ties the result is rounded towards positive infinity. This will raise an ArithmeticException if the closest integer result is not within the range [-2^31, 2^31).

Specified by:

getAsInt in interface java.util.function.IntSupplier

Throws:

java.lang.ArithmeticException - if the result overflows an int or is not finite

getAsLong

default long getAsLong()

The default implementation uses the closest representable long value of the DoubleSupplier.getAsDouble() result. In the event of ties the result is rounded towards positive infinity. This will raise an ArithmeticException if the closest integer result is not within the range [-2^63, 2^63).

Specified by:

getAsLong in interface java.util.function.LongSupplier

Throws:

java.lang.ArithmeticException - if the result overflows a long or is not finite

getAsBigInteger

default java.math.BigInteger getAsBigInteger()

Gets a result as a BigInteger.

The default implementation uses the closest representable BigInteger value of the DoubleSupplier.getAsDouble() result. In the event of ties the result is rounded towards positive infinity. This will raise an ArithmeticException if the result is not finite.

Returns:

a result

Throws:

java.lang.ArithmeticException - if the result is not finite
