Interface ReadWritablePeriod

All Superinterfaces:

ReadablePeriod

All Known Implementing Classes:

MutablePeriod

public interface ReadWritablePeriod
extends ReadablePeriod

Defines a duration of time that can be queried and modified using datetime fields.

The implementation of this interface will be mutable. It may provide more advanced methods than those in the interface.
