com.facebook.presto.jdbc.internal.joda.time.DurationFieldType
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 {@link #getField(Chronology)} method that returns the actual calculation enginefor 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 {@link #getField(Chronology)}. @author Stephen Colebourne @author Brian S O'Neill @since 1.0
