Class Millisecond
- Comparable, MonthConstants, Serializable, TimePeriod
Represents a millisecond. This class is immutable, which is a requirement
for all
RegularTimePeriod subclasses.
Millisecond()- Constructs a millisecond based on the current system time.
|
Millisecond(Date time)- Constructs a millisecond.
|
Millisecond(Date time, TimeZone zone)- Creates a millisecond.
|
Millisecond(int millisecond, int second, int minute, int hour, int day, int month, int year)- Creates a new millisecond.
|
Millisecond(int millisecond, Second second)- Constructs a millisecond.
|
int | compareTo(Object obj)- Returns an integer indicating the order of this Millisecond object
relative to the specified object:
negative == before, zero == same, positive == after.
|
boolean | equals(Object obj)- Tests the equality of this object against an arbitrary Object.
|
long | getFirstMillisecond()- Returns the first millisecond of the second.
|
long | getFirstMillisecond(Calendar calendar)- Returns the first millisecond of the time period.
|
long | getLastMillisecond()- Returns the last millisecond of the second.
|
long | getLastMillisecond(Calendar calendar)- Returns the last millisecond of the time period.
|
long | getMillisecond()- Returns the millisecond.
|
Second | getSecond()- Returns the second.
|
long | getSerialIndex()- Returns a serial index number for the millisecond.
|
int | hashCode()- Returns a hash code for this object instance.
|
RegularTimePeriod | next()- Returns the millisecond following this one.
|
void | peg(Calendar calendar)- Recalculates the start date/time and end date/time for this time period
relative to the supplied calendar (which incorporates a time zone).
|
RegularTimePeriod | previous()- Returns the millisecond preceding this one.

Millisecond
public Millisecond()
Constructs a millisecond based on the current system time.
Millisecond
public Millisecond(Date time)
Constructs a millisecond.
Millisecond
public Millisecond(Date time,
TimeZone zone) Creates a millisecond.
time - the instant in time.zone - the time zone.
Millisecond
public Millisecond(int millisecond,
int second,
int minute,
int hour,
int day,
int month,
int year) Creates a new millisecond.
millisecond - the millisecond (0-999).second - the second (0-59).minute - the minute (0-59).hour - the hour (0-23).day - the day (1-31).month - the month (1-12).year - the year (1900-9999).
Millisecond
public Millisecond(int millisecond,
Second second) Constructs a millisecond.
millisecond - the millisecond (0-999).second - the second.
compareTo
public int compareTo(Object obj)
Returns an integer indicating the order of this Millisecond object
relative to the specified object:
negative == before, zero == same, positive == after.
obj - the object to compare
- negative == before, zero == same, positive == after.
equals
public boolean equals(Object obj)
Tests the equality of this object against an arbitrary Object.
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.
getFirstMillisecond
public long getFirstMillisecond()
Returns the first millisecond of the second. This will be determined
relative to the time zone specified in the constructor, or in the
calendar instance passed in the most recent call to the
peg(Calendar) method.
- getFirstMillisecond in interface RegularTimePeriod
- The first millisecond of the second.
getLastMillisecond
public long getLastMillisecond()
Returns the last millisecond of the second. This will be
determined relative to the time zone specified in the constructor, or
in the calendar instance passed in the most recent call to the
peg(Calendar) method.
- getLastMillisecond in interface RegularTimePeriod
- The last millisecond of the second.
hashCode
public int hashCode()
Returns a hash code for this object instance. The approach described by
Joshua Bloch in "Effective Java" has been used here:

peg
public void peg(Calendar calendar)
Recalculates the start date/time and end date/time for this time period
relative to the supplied calendar (which incorporates a time zone).
- peg in interface RegularTimePeriod
calendar - the calendar (null not permitted).
