Field Details

DEFAULT_PRECISION

public static final TemporalPrecisionEnum DEFAULT_PRECISION

The default precision for this type

Constructor Details

InstantDt

public InstantDt()

Constructor which creates an InstantDt with no timne value. Note that unlike the default constructor for the Java Date or Calendar objects, this constructor does not initialize the object with the current time.

See Also:

• to create a new object that has been initialized with the current time.

InstantDt

public InstantDt(Calendar theCalendar)

Create a new DateTimeDt

InstantDt

public InstantDt(Date theDate,
 TemporalPrecisionEnum thePrecision,
 TimeZone theTimezone)

Create a new instance using the given date, precision level, and time zone

Throws:

DataFormatException - If the specified precision is not allowed for this type

InstantDt

public InstantDt(BaseDateTimeDt theDateTime)

Create a new DateTimeDt using an existing value. Use this constructor with caution, as it may create more precision than warranted (since for example it is possible to pass in a DateTime with only a year, and this constructor will convert to an InstantDt with milliseconds precision).

InstantDt

public InstantDt(Date theDate)

Create a new DateTimeDt with the given date/time and TemporalPrecisionEnum.MILLI precision

InstantDt

public InstantDt(Date theDate,
 TemporalPrecisionEnum thePrecision)

Constructor which accepts a date value and a precision value. Valid precisions values for this type are:

• TemporalPrecisionEnum.SECOND
• TemporalPrecisionEnum.MILLI

InstantDt

public InstantDt(String theString)

Create a new InstantDt from a string value

Parameters:

theString - The string representation of the string. Must be in a valid format according to the FHIR specification

Throws:

DataFormatException

Method Details

after

public boolean after(Date theDate)

Invokes Date.after(Date) on the contained Date against the given date

Throws:

NullPointerException - If the contained Date is null

before

public boolean before(Date theDate)

Invokes Date.before(Date) on the contained Date against the given date

Throws:

NullPointerException - If the contained Date is null

setToCurrentTimeInLocalTimeZone

public void setToCurrentTimeInLocalTimeZone()

Sets the value of this instant to the current time (from the system clock) and the local/default timezone (as retrieved using TimeZone.getDefault(). This TimeZone is generally obtained from the underlying OS.

isPrecisionAllowed

protected boolean isPrecisionAllowed(TemporalPrecisionEnum thePrecision)

Description copied from class: BaseDateTimeDt

To be implemented by subclasses to indicate whether the given precision is allowed by this type

Specified by:

isPrecisionAllowed in class BaseDateTimeDt

withCurrentTime

public static InstantDt withCurrentTime()

Factory method which creates a new InstantDt with millisecond precision and initializes it with the current time and the system local timezone.

getDefaultPrecisionForDatatype

protected TemporalPrecisionEnum getDefaultPrecisionForDatatype()

Returns the default precision for this datatype

Specified by:

getDefaultPrecisionForDatatype in class BaseDateTimeDt

• DEFAULT_PRECISION
