Constructor Detail

MovingPeaks

public MovingPeaks()

Creates a new instance of MovingPeaks.

Method Detail

getClone

public MovingPeaks getClone()

Create a cloned copy of the current object and return it. In general the created copy will be a deep copy of the provided instance. As a result this operation an be quite expensive if used incorrectly.

Specified by:

getClone in interface Cloneable

Specified by:

getClone in class ContinuousFunction

Returns:

An exact clone of the current object instance.

See Also:

Object.clone()

getMinimum

public Object getMinimum()

Accessor for the function minimum. This is the minimum value of the function in the given domain.

Overrides:

getMinimum in class ContinuousFunction

Returns:

The minimum function value.

getMaximum

public Object getMaximum()

Accessor for the function maximum. This is the maximum value of the function in the given domain.

Overrides:

getMaximum in class ContinuousFunction

Returns:

The maximum of the function.
