Method Detail

then

public TimeSpecifier then(TimeSpecifier specfier)

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))

Specified by:

then in interface TimeSpecifier

afterDoing

public TimeSpecifier afterDoing(TimeSpecifier specfier)

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))

Specified by:

afterDoing in interface TimeSpecifier

hasPredecessor

protected boolean hasPredecessor()

Does this TimeSpecifier have a predecessor specfier.

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Clone this object.

Overrides:

clone in class java.lang.Object

Throws:

java.lang.CloneNotSupportedException

value

public long value()

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