Class ParameterAggregation<E extends ParameterObjectInterface>

java.lang.Object

net.finmath.marketdata.calibration.ParameterAggregation<E>

All Implemented Interfaces:

ParameterObjectInterface

public class ParameterAggregation<E extends ParameterObjectInterface>
extends Object
implements ParameterObjectInterface

Combine a set of parameter vectors to a single parameter vector. The class is a little helper class which can combine a set of double[] parameter-vectors to a single large double[] parameter-vector. More precisely: this class combines a set of objects implementing ParameterObjectInterface to a single object by implementing ParameterObjectInterface with the combined parameter. An application is an optimization problem which depends on different parametrized objects, using a solver/optimizer which operates an a single parameter vector.

Constructor Detail

ParameterAggregation

public ParameterAggregation()

Create a collection of parametrized objects.

ParameterAggregation

public ParameterAggregation(Set<E> parameters)

Create a collection of parametrized objects. The constructor will internally create a (shallow) copy of the set passed to it.

Parameters:

parameters - A set of objects implementing ParameterObjectInterface to be combined to a single object.

ParameterAggregation

public ParameterAggregation(E[] parameters)

Create a collection of parametrized objects. The constructor will internally create a (shallow) copy of the set passed to it.

Parameters:

parameters - A set of objects implementing ParameterObjectInterface to be combined to a single object.

Method Detail

add

public void add(E parameterObject)

Add an object this parameterization.

Parameters:

parameterObject - The parameter object to add to this parameterization

remove

public void remove(E parameterObject)

Remove an object from this parameterization.

Parameters:

parameterObject - The parameter object to remove.

getParameter

public double[] getParameter()

Description copied from interface: ParameterObjectInterface

Get the current parameter associated with the state of the objects.

Specified by:

getParameter in interface ParameterObjectInterface

Returns:

The parameter.

setParameter

public void setParameter(double[] parameter)

Description copied from interface: ParameterObjectInterface

Set the current parameter and change the state of the objects.

Specified by:

setParameter in interface ParameterObjectInterface

Parameters:

parameter - The parameter associated with the new state of the objects.

getObjectsToModifyForParameter

public Map<E,double[]> getObjectsToModifyForParameter(double[] parameter)

getCloneForParameter

public CurveInterface getCloneForParameter(double[] value)
                                    throws CloneNotSupportedException

Description copied from interface: ParameterObjectInterface

Create a clone with a modified parameter.

Specified by:

getCloneForParameter in interface ParameterObjectInterface

Parameters:

value - The new parameter.

Returns:

A clone with an otherwise modified parameter.

Throws:

CloneNotSupportedException - Thrown, when the curve could not be cloned.
