DurationFieldType ("The Adobe AEM Quickstart and Web Application.")

java.lang.Object
- org.joda.time.DurationFieldType

All Implemented Interfaces:

java.io.Serializable
```
public abstract class DurationFieldType
extends java.lang.Object
implements java.io.Serializable
```
Identifies a duration field, such as years or minutes, in a chronology-neutral way.
A duration field type defines the type of the field, such as hours. If does not directly enable any calculations, however it does provide a getField(Chronology) method that returns the actual calculation engine for a particular chronology.
Instances of DurationFieldType are singletons. They can be compared using ==.
If required, you can create your own field, for example a quarters. You must create a subclass of DurationFieldType that defines the field type. This class returns the actual calculation engine from getField(Chronology).
