java.lang.Objectorg.jfree.data.time.RegularTimePeriod
org.jfree.data.time.Millisecond
Represents a millisecond.
This class is immutable, which is a requirement for all RegularTimePeriod
subclasses.
Field Summary | |
static int |
FIRST_MILLISECOND_IN_SECOND
A constant for the first millisecond in a second. |
static int |
LAST_MILLISECOND_IN_SECOND
A constant for the last millisecond in a second. |

Constructor Summary | |
Millisecond()
Constructs a millisecond based on the current system time. |
|
Millisecond(java.util.Date time)
Constructs a millisecond. |
|
Millisecond(java.util.Date time,

public boolean equals(java.lang.Object obj)
This method will return true ONLY if the object is a Millisecond object representing the same millisecond as this instance.
obj
- the object to compare
true
if milliseconds and seconds of this and object
are the same.public int hashCode()
