Class Minute
- Comparable, MonthConstants, Serializable, TimePeriod
Represents a minute. This class is immutable, which is a requirement for
all
RegularTimePeriod subclasses.
Minute()- Constructs a new Minute, based on the system date/time.
|
Minute(Date time)- Constructs a new Minute, based on the supplied date/time.
|
Minute(Date time, TimeZone zone)- Constructs a new Minute, based on the supplied date/time and timezone.
|
Minute(int minute, int hour, int day, int month, int year)- Creates a new minute.
|
Minute(int minute, Hour hour)- Constructs a new Minute.
|
int | compareTo(Object o1)- Returns an integer indicating the order of this Minute 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.
|
Day | getDay()- Returns the day.
|
long | getFirstMillisecond()- Returns the first millisecond of the minute.
|
long | getFirstMillisecond(Calendar calendar)- Returns the first millisecond of the minute.
|
Hour | getHour()- Returns the hour.
|
int | getHourValue()- Returns the hour.
|
long | getLastMillisecond()- Returns the last millisecond of the minute.
|
long | getLastMillisecond(Calendar calendar)- Returns the last millisecond of the minute.
|
int | getMinute()- Returns the minute.
|
long | getSerialIndex()- Returns a serial index number for the minute.
|
int | hashCode()- Returns a hash code for this object instance.
|
RegularTimePeriod | next()- Returns the minute following this one.
|
static Minute | parseMinute(String s)- Creates a Minute instance by parsing a string.
|
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 minute preceding this one.

FIRST_MINUTE_IN_HOUR
public static final int FIRST_MINUTE_IN_HOUR
Useful constant for the first minute in a day.
LAST_MINUTE_IN_HOUR
public static final int LAST_MINUTE_IN_HOUR
Useful constant for the last minute in a day.
Minute
public Minute()
Constructs a new Minute, based on the system date/time.
Minute
public Minute(Date time)
Constructs a new Minute, based on the supplied date/time.
time - the time (null not permitted).
Minute
public Minute(Date time,
TimeZone zone) Constructs a new Minute, based on the supplied date/time and timezone.
time - the time (null not permitted).zone - the time zone (null not permitted).
Minute
public Minute(int minute,
int hour,
int day,
int month,
int year) Creates a new minute.
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).
Minute
public Minute(int minute,
Hour hour) Constructs a new Minute.
minute - the minute (0 to 59).hour - the hour (null not permitted).
compareTo
public int compareTo(Object o1)
Returns an integer indicating the order of this Minute object relative
to the specified object:
negative == before, zero == same, positive == after.
- 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 Minute object
representing the same minute as this instance.
obj - the object to compare (null permitted).
true if the minute and hour value of this and the
object are the same.
getFirstMillisecond
public long getFirstMillisecond()
Returns the first millisecond of the minute. 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 minute.
getLastMillisecond
public long getLastMillisecond()
Returns the last millisecond of the minute. 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 minute.
getMinute
public int getMinute()
Returns the minute.
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:

parseMinute
public static Minute parseMinute(String s)
Creates a Minute instance by parsing a string. The string is assumed to
be in the format "YYYY-MM-DD HH:MM", perhaps with leading or trailing
whitespace.
s - the minute string to parse.
null, if the string is not parseable, the minute
otherwise.
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).
