Class DurationFieldType

  org.joda.time.DurationFieldType

All Implemented Interfaces:: Serializable

public abstract class DurationFieldType
extends Object
implements Serializable
extends Object
implements 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).
