public interface TimeSpecifier
extends java.lang.Cloneable, Value

An interface for objects that specify some specifier for a Timestamp.

Method Summary

TimeSpecifier	afterDoing(TimeSpecifier specifier) After doing the specfied TimeSpecifier, do this TimeSpecifier.
Timestamp	instantiate(Timestamp t) Instantiate this TimeSpecifier w.r.t a particular Timestamp.
TimeSpecifier	then(TimeSpecifier specifier) Do this TimeSpecifier, then do another TimeSpecifier.
long	value() Get the value.

Method Detail

then

TimeSpecifier then(TimeSpecifier specifier)

Do this TimeSpecifier, then do another TimeSpecifier. This gets more modification. N.B. spec1.then(spec2) == spec2.afterDoing(spec1) spec1.then(spec2).then(spec3) == spec3.afterDoing(spec2.afterDoing(spec1))

afterDoing

TimeSpecifier afterDoing(TimeSpecifier specifier)

After doing the specfied TimeSpecifier, do this TimeSpecifier. This gets more modification. N.B. spec1.then(spec2) == spec2.afterDoing(spec1) spec1.then(spec2).then(spec3) == spec3.afterDoing(spec2.afterDoing(spec1))

instantiate

Timestamp instantiate(Timestamp t)

Instantiate this TimeSpecifier w.r.t a particular Timestamp. It returns a Timestamp which has been modified by the amount of the TimeSpecifier.

value

long value()

Get the value. When TimeDirection is FORWARD, then the value is positive, and when TimeDirection is BACKWARD, then the value is negative.
