public final class SwaptionSurfaceExpirySimpleMoneynessParameterMetadata
extends Object
implements ParameterMetadata, org.joda.beans.ImmutableBean, Serializable

Surface node metadata for a surface node for swaptions with a specific time to expiry and simple moneyness.

This typically represents a node of swaption volatility surface parameterized by expiry and simple moneyness.

Creates node using swap convention, year fraction, simple moneyness and label.

Parameters:

yearFraction - the year fraction

simpleMoneyness - the simple moneyness

label - the label to use

Returns:

the metadata

getIdentifier

public Pair<Double,Double> getIdentifier()

Description copied from interface: ParameterMetadata

Returns an object used to identify the parameter.

A good choice of identifier is one that makes sense to the user and can easily be created as part of a scenario definition. For example, many nodes types are naturally identified by a tenor.

The identifier must satisfy the following criteria:

• It must be non-null
• It should be unique within a single data set
• It should have a sensible implementation of hashCode() and equals().

Otherwise the choice of identifier is free and the system makes no assumptions about it.

Specified by:

getIdentifier in interface ParameterMetadata

Returns:

an object used to uniquely identify the parameter within the data

meta

public static SwaptionSurfaceExpirySimpleMoneynessParameterMetadata.Meta meta()

The meta-bean for SwaptionSurfaceExpirySimpleMoneynessParameterMetadata.

Returns:

the meta-bean, not null

metaBean

public SwaptionSurfaceExpirySimpleMoneynessParameterMetadata.Meta metaBean()

Specified by:

metaBean in interface org.joda.beans.Bean

getYearFraction

public double getYearFraction()

Gets the year fraction of the surface node.

This is the time to expiry that the node on the surface is defined as. There is not necessarily a direct relationship with a date from an underlying instrument.

Returns:

the value of the property

getSimpleMoneyness

public double getSimpleMoneyness()

Gets the simple moneyness of the surface node.

This is defined as strike - forward.

Returns:

the value of the property

getLabel

public String getLabel()

Gets the label that describes the node.

Specified by:

getLabel in interface ParameterMetadata

Returns:

the value of the property, not empty

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
