Inherited Methods

From class org.jfree.data.time.RegularTimePeriod

static RegularTimePeriod	createInstance(Class c, Date millisecond, TimeZone zone) Creates a time period that includes the specified millisecond, assuming the given time zone.
static Class	downsize(Class c) Returns a subclass of `RegularTimePeriod` that is smaller than the specified class.
Date	getEnd() Returns the date/time that marks the end of the time period.
abstract long	getFirstMillisecond(Calendar calendar) Returns the first millisecond of the time period, evaluated using the supplied calendar (which incorporates a timezone).
long	getFirstMillisecond(TimeZone zone) This method is deprecated. As of 1.0.3, you should avoid using this method (it creates a new Calendar instance every time it is called). You are advised to call `getFirstMillisecond(Calendar)` instead.
abstract long	getFirstMillisecond() Returns the first millisecond of the time period.
long	getLastMillisecond(TimeZone zone) This method is deprecated. As of 1.0.3, you should avoid using this method (it creates a new Calendar instance every time it is called). You are advised to call `getLastMillisecond(Calendar)` instead.
abstract long	getLastMillisecond(Calendar calendar) Returns the last millisecond of the time period, evaluated using the supplied calendar (which incorporates a timezone).
abstract long	getLastMillisecond() Returns the last millisecond of the time period.
long	getMiddleMillisecond(Calendar calendar) Returns the millisecond closest to the middle of the time period, evaluated using the supplied calendar (which incorporates a timezone).
long	getMiddleMillisecond() Returns the millisecond closest to the middle of the time period.
long	getMiddleMillisecond(TimeZone zone) This method is deprecated. As of 1.0.3, you should avoid using this method (it creates a new Calendar instance every time it is called). You are advised to call `getMiddleMillisecond(Calendar)` instead.
abstract long	getSerialIndex() Returns a serial index number for the time unit.
Date	getStart() Returns the date/time that marks the start of the time period.
abstract RegularTimePeriod	next() Returns the time period following this one, or `null` if some limit has been reached.
abstract 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).
abstract RegularTimePeriod	previous() Returns the time period preceding this one, or `null` if some lower limit has been reached.
String	toString() Returns a string representation of the time period.

Public Methods

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.

Parameters

o1	object to compare.

Returns

negative == before, zero == same, positive == after.

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.

Parameters

obj	the object to compare (`null` permitted).

Returns

true if the minute and hour value of this and the object are the same.

public Day getDay ()

Returns the day.

Returns

The day.

public long getFirstMillisecond (Calendar calendar)

Returns the first millisecond of the minute.

Parameters

calendar	the calendar which defines the timezone (`null` not permitted).

Returns

The first millisecond.

Throws

NullPointerException	if `calendar` is `null`.

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.

Returns

The first millisecond of the minute.

public Hour getHour ()

Returns the hour.

Returns

The hour (never null).

public int getHourValue ()

Returns the hour.

Returns

The hour.

public long getLastMillisecond (Calendar calendar)

Returns the last millisecond of the minute.

Parameters

calendar	the calendar / timezone (`null` not permitted).

Returns

The last millisecond.

Throws

NullPointerException	if `calendar` is `null`.

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.

Returns

The last millisecond of the minute.

public int getMinute ()

Returns the minute.

Returns

The minute.

public long getSerialIndex ()

Returns a serial index number for the minute.

Returns

The serial index number.

public int hashCode ()

Returns a hash code for this object instance. The approach described by Joshua Bloch in "Effective Java" has been used here:

http://developer.java.sun.com/developer/Books/effectivejava /Chapter3.pdf

Returns

A hash code.

public RegularTimePeriod next ()

Returns the minute following this one.

Returns

The minute following this one.

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.

Parameters

s	the minute string to parse.

Returns

null, if the string is not parseable, the minute otherwise.

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).

Parameters

calendar	the calendar (`null` not permitted).

public RegularTimePeriod previous ()

Returns the minute preceding this one.

Returns

The minute preceding this one.
