Method Detail

init

public void init()

Description copied from class: DblSequence

Initializes this stream. This method is supposed to be called once before repeated calls to DblSequence.nextDbl() can be made.

Overrides:

init in class DblSequence

nextDbl

public double nextDbl()

Description copied from class: DblSequence

Returns the next number in this number stream.

Specified by:

nextDbl in class DblSequence

getNumericalMean

public double getNumericalMean()

Description copied from class: DblSequence

Returns the arithmetic mean of the values returned by DblSequence.nextDbl().

Overrides:

getNumericalMean in class DblSequence

getValueRange

public Pair<Double,Double> getValueRange()

Description copied from class: DblSequence

This method computes the minimum and maximum support values (range of possible values) of this stream.

Overrides:

getValueRange in class DblSequence

Returns:

A Pair containing the minimum and maximum support values.

toString

public String toString()

Overrides:

toString in class Object

getSubStreams

public DblSequence[] getSubStreams()

setSubStreams

public void setSubStreams(DblSequence... subStreams)

Sets the sub-streams to compute the values of this number stream.

Parameters:

subStreams - The sub-streams to use.
