Class NullConverter

java.lang.Object

org.joda.time.convert.AbstractConverter

org.joda.time.convert.NullConverter

All Implemented Interfaces:

Converter, DurationConverter, InstantConverter, IntervalConverter, PartialConverter, PeriodConverter

class NullConverter
extends AbstractConverter
implements InstantConverter, PartialConverter, DurationConverter, PeriodConverter, IntervalConverter

NullConverter converts null to an instant, partial, duration, period or interval. Null means now for instant/partial, zero for duration/period and from now to now for interval.

Since:

1.0

Method Detail

getDurationMillis

public long getDurationMillis(java.lang.Object object)

Gets the millisecond duration, which is zero.

Specified by:

getDurationMillis in interface DurationConverter

Parameters:

object - the object to convert, which is null

Returns:

the millisecond duration

setInto

public void setInto(ReadWritablePeriod duration,
                    java.lang.Object object,
                    Chronology chrono)

Sets the given ReadWritableDuration to zero milliseconds.

Specified by:

setInto in interface PeriodConverter

Parameters:

duration - duration to get modified

object - the object to convert, which is null

chrono - the chronology to use

Throws:

java.lang.NullPointerException - if the duration is null

setInto

public void setInto(ReadWritableInterval writableInterval,
                    java.lang.Object object,
                    Chronology chrono)

Extracts interval endpoint values from an object of this converter's type, and sets them into the given ReadWritableInterval.

Specified by:

setInto in interface IntervalConverter

Parameters:

writableInterval - interval to get modified, not null

object - the object to convert, which is null

chrono - the chronology to use, may be null

Throws:

java.lang.NullPointerException - if the interval is null

getSupportedType

public java.lang.Class<?> getSupportedType()

Returns null.

Specified by:

getSupportedType in interface Converter

Returns:

null
