com.altova.types.Duration

This class enables you to process XML attributes or elements of type xs:duration.

Constructors

	Name	Description
	Duration(Duration newvalue)	Initializes a new instance of the Duration class to the Duration object supplied as argument.
	Duration(int newyear, int newmonth, int newday, int newhour, int newminute, int newsecond, double newpartsecond, boolean newisnegative)	Initializes a new instance of the Duration class to a duration built from parts supplied as arguments.

Methods

Name

Description

static Duration getFromDayTime( int newday, int newhour, int newminute, int newsecond, double newpartsecond )

Returns a Duration object created from the number of days, hours, minutes, seconds, and fractional second parts supplied as argument.

static Duration getFromYearMonth( int newyear, int newmonth )

Returns a Duration object created from the number of years and months supplied as argument.

static Duration parse( String s )

Returns a Duration object created from the string supplied as argument. For example, the string -P1Y1M1DT1H1M1.333S can be used to create a negative duration of one year, one month, one day, one hour, one minute, one second, and 0.333 fractional parts of a second. To create a negative duration, append the minus sign ( - ) to the string.

static Duration parse( String s, ParseType pt )

Returns a Duration object created from the string supplied as argument, using a specific parse format. The parse format can be any of the following:

ParseType.DAYTIME	May be used when the string s consists of any of the following: days, hours, minutes, seconds, fractional second parts, for example -P4DT4H4M4.774S.
ParseType.DURATION	May be used when the string s consists of any of the following: years, months, days, hours, minutes, seconds, fractional second parts, for example P1Y1M1DT1H1M1.333S.
ParseType.YEARMONTH	May be used when the string s consists of any of the following: years, months. For example: P3Y2M.

int getDay()

Returns the number of days in the current Duration instance.

long getDayTimeValue()

Returns the day and time value (in milliseconds) of the current Duration instance. Years and months are ignored.

int getHour()

Returns the number of hours in the current Duration instance.

int getMillisecond()

Returns the number of milliseconds in the current Duration instance.

int getMinute()

Returns the number of minutes in the current Duration instance.

int getMonth()

Returns the number of months in the current Duration instance.

double getPartSecond()

Returns the number of fractional second parts in the current Duration instance.

int getSecond()

Returns the number of seconds in the current Duration instance.

int getYear()

Returns the number of years in the current Duration instance.

int getYearMonthValue()

Returns the year and month value (in months) of the current Duration instance. Days, hours, seconds, and milliseconds are ignored.

boolean isNegative()

Returns Boolean true if the current Duration instance is negative.

void setDayTimeValue(long l)

Sets the duration to the number of milliseconds supplied as argument, affecting only the day and time part of the duration.

void setNegative( boolean isnegative )

Converts the current Duration instance to a negative duration.

void setYearMonthValue(int l)

Sets the duration to the number of months supplied as argument. Only the years and months part of the duration is affected.

String toString()

Returns the string representation of the current Duration instance, for example:

-P4DT4H4M4.774S

String toYearMonthString()

Returns the string representation of the YearMonth part of the current Duration instance, for example:

P1Y2M

Examples

Before using the following code listings in your program, ensure the Altova types are imported:

import com.altova.types.*;
import com.altova.types.Duration.ParseType;

The following code listing illustrates various ways to create Duration objects:

protected static void ExampleDuration()
{
// Create a negative duration of 1 year, 1 month, 1 day, 1 hour, 1 minute, 1 second,
// and 0.333 fractional second parts
Duration dr = new Duration(1, 1, 1, 1, 1, 1, .333, true);

// Create a duration from an existing Duration object
Duration dr1 = new Duration(dr);

// Create a duration of 4 days, 4 hours, 4 minutes, 4 seconds, .774 fractional second parts
Duration dr2 = Duration.getFromDayTime(4, 4, 4, 4, .774);

// Create a duration of 3 years and 2 months
Duration dr3 = Duration.getFromYearMonth(3, 2);

// Create a duration from a string
Duration dr4 = Duration.parse("-P4DT4H4M4.774S");

// Create a duration from a string, using specific parse formats
Duration dr5 = Duration.parse("-P1Y1M1DT1H1M1.333S", ParseType.DURATION);
Duration dr6 = Duration.parse("P3Y2M", ParseType.YEARMONTH);
Duration dr7 = Duration.parse("-P4DT4H4M4.774S", ParseType.DAYTIME);
}

The following code listing illustrates getting and setting the value of Duration objects:

protected static void DurationExample2()
{
// Create a duration of 1 year, 2 month, 3 days, 4 hours, 5 minutes, 6 seconds,
// and 333 milliseconds
Duration dr = new Duration(1, 2, 3, 4, 5, 6, .333, false);
// Output the number of days in this duration
System.out.println(dr.getDay());

// Create a positive duration of one year and 333 milliseconds
Duration dr1 = new Duration(1, 0, 0, 0, 0, 0, .333, false);
// Output the day and time value in milliseconds
System.out.println(dr1.getDayTimeValue());

// Create a positive duration of 1 year, 1 month, 1 day, 1 hour, 1 minute, 1 second,
// and 333 milliseconds
Duration dr2 = new Duration(1, 1, 1, 1, 1, 1, .333, false);
// Output the year and month value in months
System.out.println(dr2.getYearMonthValue());

// Create a positive duration of 1 year and 1 month
Duration dr3 = new Duration(1, 1, 0, 0, 0, 0, 0, false);
// Output the value
System.out.println("The duration is now: " + dr3.toString());
// Set the DayTime part of duration to 1000 milliseconds
dr3.setDayTimeValue(1000);
// Output the value
System.out.println("The duration is now: " + dr3.toString());
// Set the YearMonth part of duration to 1 month
dr3.setYearMonthValue(1);
// Output the value
System.out.println("The duration is now: " + dr3.toString());
// Output the year and month part of the duration
System.out.println("The YearMonth part of the duration is: " + dr3.toYearMonthString());
}
