public final class CmsPeriod
extends Object
implements org.joda.beans.ImmutableBean, Serializable
```
A period over which a CMS coupon or CMS caplet/floorlet payoff is paid.
This represents a single payment period within a CMS leg. This class specifies the data necessary to calculate the value of the period. The payment period contains the unique accrual period. The value of the period is based on the observed value of SwapIndex.
The payment is a CMS coupon, CMS caplet or CMS floorlet. The pay-offs are, for a swap index on the fixingDate of 'S' and an year fraction 'a'
CMS Coupon: a * S
CMS Caplet: a * (S-K)^+ ; K=caplet
CMS Floorlet: a * (K-S)^+ ; K=floorlet
If caplet (floorlet) is not null, the payment is a caplet (floorlet). If both of caplet and floorlet are null, this class represents a CMS coupon payment. Thus at least one of the fields must be null.
A CmsPeriod is bound to data that changes over time, such as holiday calendars. If the data changes, such as the addition of a new holiday, the resolved form will not be updated. Care must be taken when placing the resolved form in a cache or persistence layer.

- Method Detail
  - getCmsPeriodType
```
public CmsPeriodType getCmsPeriodType()
```
    Obtains the type of the CMS period.
    The period type is caplet, floorlet or coupon.
    
    Returns:
    
    the CMS period type
  - getStrike
```
public double getStrike()
```
    Obtains the strike value.
    If the CMS period type is coupon, 0 is returned.
    
    Returns:
    
    the strike value
  - toCouponEquivalent
```
public CmsPeriod toCouponEquivalent()
```
    Return the CMS coupon equivalent to the period.
    For cap or floor the result is the coupon with the same dates and index but with no cap or floor strike.
    
    Returns:
    
    the CMS coupon
  - meta
```
public static CmsPeriod.Meta meta()
```
    The meta-bean for CmsPeriod.
    
    Returns:
    
    the meta-bean, not null
  - builder
```
public static CmsPeriod.Builder builder()
```
    Returns a builder used to create an instance of the bean.
    
    Returns:
    
    the builder, not null
  - metaBean
```
public CmsPeriod.Meta metaBean()
```
    Specified by:
    
    metaBean in interface org.joda.beans.Bean
  - getCurrency
```
public Currency getCurrency()
```
    Gets the primary currency of the payment period.
    The amounts of the notional are usually expressed in terms of this currency, however they can be converted from amounts in a different currency.
    
    Returns:
    
    the value of the property, not null
  - getNotional
```
public double getNotional()
```
    Gets the notional amount, positive if receiving, negative if paying.
    The notional amount applicable during the period. The currency of the notional is specified by currency.
    
    Returns:
    
    the value of the property
  - getStartDate
```
public LocalDate getStartDate()
```
    Gets the start date of the payment period.
    This is the first date in the period. If the schedule adjusts for business days, then this is the adjusted date.
    
    Returns:
    
    the value of the property, not null
  - getEndDate
```
public LocalDate getEndDate()
```
    Gets the end date of the payment period.
    This is the last date in the period. If the schedule adjusts for business days, then this is the adjusted date.
    
    Returns:
    
    the value of the property, not null
  - getUnadjustedStartDate
```
public LocalDate getUnadjustedStartDate()
```
