All Known Implementing Classes:

DefaultAbsoluteInstant, DefaultAbsoluteInterval, DefaultEditableRelativeInstant, DefaultRelativeInstant, DefaultRelativeInterval

public interface Time

This object is in the top level of the time hierarchy. All the temporal objects have to inherit of this interface.

Method Summary

Modifier and Type	Method and Description
Chronology	getChronology() Gets the chronology of the instant.
boolean	intersects(Time time) Does this time intersects with the time passed.
boolean	isAbsolute() Checks if the time is an absolute temporal type, that is an object that doesn't has a time zone.
boolean	isInstant() Checks if the time is an instant, that is an object that represents a position in a time scale.
boolean	isInterval() Checks if the time is an interval, that is an object that represents a period of time between two instants.
boolean	isRelative() Checks if the time is a relative temporal type, that is an object that has a Chronology that establish how a time object can be converted into other object with date time fields.

Method Detail

intersects

boolean intersects(Time time)

Does this time intersects with the time passed.

Parameters:

time - an instant to check against, null means now

Returns:

true if the time intersects with the time passed in

isRelative

boolean isRelative()

Checks if the time is a relative temporal type, that is an object that has a Chronology that establish how a time object can be converted into other object with date time fields.

Returns:

true

isAbsolute

boolean isAbsolute()

Checks if the time is an absolute temporal type, that is an object that doesn't has a time zone.

Returns:

true if the time object is absolute

isInterval

boolean isInterval()

Checks if the time is an interval, that is an object that represents a period of time between two instants.

Returns:

true if the time object is an interval

isInstant

boolean isInstant()

Checks if the time is an instant, that is an object that represents a position in a time scale. In practice, an instant is an interval whose duration is less than the resolution of the time scale.

Returns:

true if the time object is an instant.

getChronology

Chronology getChronology()

Gets the chronology of the instant. The Chronology provides conversion from the millisecond value to meaningful fields in a particular calendar system.

Returns:

the Chronology, never null
