public final class Tenor
extends java.lang.Object
implements java.lang.Comparable<Tenor>, java.time.temporal.TemporalAmount, java.io.Serializable
```
A tenor indicating how long it will take for a financial instrument to reach maturity.
A tenor is allowed to be any non-negative non-zero period of days, weeks, month or years. This class provides constants for common tenors which are best used by static import.
Each tenor is based on a Period. The months and years of the period are not normalized, thus it is possible to have a tenor of 12 months and a different one of 1 year. When used, standard date addition rules apply, thus there is no difference between them. Call normalized() to apply normalization.
Usage
Tenor implements TemporalAmount allowing it to be directly added to a date:
```
  LocalDate later = baseDate.plus(tenor);
 
```

```
public static Tenor parse(java.lang.String toParse)
```
    Parses a formatted string representing the tenor.
    The format can either be based on ISO-8601, such as 'P3M' or without the 'P' prefix e.g. '2W'.

```
    Gets the underlying period of the tenor.
    
    Returns:
    
    the period
  - normalized
```
public Tenor normalized()
```
    Normalizes the months and years of this tenor.
    This method returns a normalized tenor of an equivalent length. If the period is exactly 1 year then the result will be expressed as 12 months. Otherwise, the result will be expressed using Period.normalized().
    
    Returns:
    
    the normalized tenor
  - isWeekBased
```
public boolean isWeekBased()
```
    Checks if the tenor is week-based.
    A week-based tenor consists of an integral number of weeks. There must be no day, month or year element.
    
    Returns:
    
    true if this is week-based
  - isMonthBased
```
public boolean isMonthBased()
```
    Checks if the tenor is month-based.
    A month-based tenor consists of an integral number of months. Any year-based tenor is also counted as month-based. There must be no day or week element.
    
    Returns:
    
    true if this is month-based
  - get
```
public long get(java.time.temporal.TemporalUnit unit)
```
    Gets the value of the specified unit.
    This will return a value for the years, months and days units. Note that weeks are not included. All other units throw an exception.
    This method implements TemporalAmount. It is not intended to be called directly.
    
    Specified by:
    
    get in interface java.time.temporal.TemporalAmount
    
    Parameters:
    
    unit - the unit to query
    
    Returns:
    
    the value of the unit
    
    Throws:
    
    java.time.temporal.UnsupportedTemporalTypeException - if the unit is not supported
  - getUnits
```
public java.util.List<java.time.temporal.TemporalUnit> getUnits()
```
    Gets the units supported by a tenor.
    This returns a list containing years, months and days. Note that weeks are not included.
    This method implements TemporalAmount. It is not intended to be called directly.
    
    Specified by:
    
    getUnits in interface java.time.temporal.TemporalAmount
    
    Returns:
    
    a list containing the years, months and days units
  - addTo
```
public java.time.temporal.Temporal addTo(java.time.temporal.Temporal temporal)
```
    Adds this tenor to the specified date.
    This method implements TemporalAmount. It is not intended to be called directly. Use LocalDate.plus(TemporalAmount) instead.
    
    Specified by:
    
    addTo in interface java.time.temporal.TemporalAmount
    
    Parameters:
    
    temporal - the temporal object to add to
    
    Returns:
    
    the result with this tenor added
    
    Throws:
    
    java.time.DateTimeException - if unable to add
    
    java.lang.ArithmeticException - if numeric overflow occurs
  - subtractFrom
```
public java.time.temporal.Temporal subtractFrom(java.time.temporal.Temporal temporal)
```
    Subtracts this tenor from the specified date.
    This method implements TemporalAmount. It is not intended to be called directly. Use LocalDate.minus(TemporalAmount) instead.
    
    Specified by:
    
    subtractFrom in interface java.time.temporal.TemporalAmount
    
    Parameters:
    
    temporal - the temporal object to subtract from
    
    Returns:
    
    the result with this tenor subtracted
    
    Throws:
    
    java.time.DateTimeException - if unable to subtract
    
    java.lang.ArithmeticException - if numeric overflow occurs
  - compareTo
```
public int compareTo(Tenor other)
```
    Compares this tenor to another tenor.
    Comparing tenors is a hard problem in general, but for commonly used tenors the outcome is as expected. If the two tenors are both based on days, then comparison is easy. If the two tenors are both based on months/years, then comparison is easy. Otherwise, months are converted to days to form an estimated length in days which is compared. The conversion from months to days divides by 12 and then multiplies by 365.2425. As a result, this method is compatible with equals(Object) for tenors less than 400 years.
    The resulting order places:
    
    a 1 month tenor between 30 and 31 days
    a 2 month tenor between 60 and 61 days
    a 3 month tenor between 91 and 92 days
    a 6 month tenor between 182 and 183 days
    a 1 year tenor between 365 and 366 days
    a 4 year tenor between 1460 and 1461 days
    Specified by:
    
    compareTo in interface java.lang.Comparable<Tenor>
    
    Parameters:
    
    other - the other tenor
    
    Returns:
    
    negative if this is less than the other, zero if equal and positive if greater
  - equals
```
public boolean equals(java.lang.Object obj)
```
    Checks if this tenor equals another tenor.
    The comparison checks the tenor period.
    
    Overrides:
    
    equals in class java.lang.Object
    
    Parameters:
    
    obj - the other tenor, null returns false
    
    Returns:
    
    true if equal
  - hashCode
```
public int hashCode()
```
    Returns a suitable hash code for the tenor.
    
    Overrides:
    
    hashCode in class java.lang.Object
    
    Returns:
    
    the hash code
  - toString
```
public java.lang.String toString()
```
    Returns a formatted string representing the tenor.
    The format is a combination of the quantity and unit, such as 1D, 2W, 3M, 4Y.
    
    Overrides:
    
    toString in class java.lang.Object
    
    Returns:
    
    the formatted tenor
