TimePeriod

public TimePeriod()

Creates a new Year, based on the current system date/time.

TimePeriod

public TimePeriod(Date start,
 Date end)

Creates a time period representing a single year.

Parameter:

start -

end -

year - the year.

Methodendetails

getFirstMillisecond

public long getFirstMillisecond()

Returns the first millisecond of the year. 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.

Angegeben von:

getFirstMillisecond in Klasse org.jfree.data.time.RegularTimePeriod

Gibt zurück:

The first millisecond of the year.

• getLastMillisecond()

getLastMillisecond

public long getLastMillisecond()

Returns the last millisecond of the year. 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.

Angegeben von:

getLastMillisecond in Klasse org.jfree.data.time.RegularTimePeriod

Gibt zurück:

The last millisecond of the year.

• getFirstMillisecond()

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).

Angegeben von:

peg in Klasse org.jfree.data.time.RegularTimePeriod

Parameter:

calendar - the calendar (null not permitted).

Seit:

1.0.3

getSerialIndex

public long getSerialIndex()

Returns a serial index number for the year.

The implementation simply returns the second of the start time number (e.g. 2002).

Angegeben von:

getSerialIndex in Klasse org.jfree.data.time.RegularTimePeriod

Gibt zurück:

The serial index number.

getFirstMillisecond

public long getFirstMillisecond(Calendar calendar)

Returns the first millisecond of the year, evaluated using the supplied calendar (which determines the time zone).

Angegeben von:

getFirstMillisecond in Klasse org.jfree.data.time.RegularTimePeriod

Parameter:

calendar - the calendar (null not permitted).

Gibt zurück:

The first millisecond of the year.

Löst aus:

NullPointerException - if calendar is null.

getLastMillisecond

public long getLastMillisecond(Calendar calendar)

Returns the last millisecond of the year, evaluated using the supplied calendar (which determines the time zone).

Angegeben von:

getLastMillisecond in Klasse org.jfree.data.time.RegularTimePeriod

Parameter:

calendar - the calendar (null not permitted).

Gibt zurück:

The last millisecond of the year.

Löst aus:

NullPointerException - if calendar is null.

equals

public boolean equals(Object obj)

Tests the equality of this Year object to an arbitrary object. Returns true if the target is a Year instance representing the same year as this object. In all other cases, returns false.

Setzt außer Kraft:

equals in Klasse Object

Parameter:

obj - the object (null permitted).

Gibt zurück:

true if the year of this and the object are the same.

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:

Setzt außer Kraft:

hashCode in Klasse Object

Gibt zurück:

A hash code.

compareTo

public int compareTo(Object o1)

Returns an integer indicating the order of this Year object relative to the specified object: negative == before, zero == same, positive == after.

Angegeben von:

compareTo in Schnittstelle Comparable

Parameter:

o1 - the object to compare.

Gibt zurück:

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

toString

public String toString()

Returns a string representing the year..

Setzt außer Kraft:

toString in Klasse org.jfree.data.time.RegularTimePeriod

Gibt zurück:

A string representing the year.
