Timestamp

public Timestamp()

Timestamp

public Timestamp(ZonedDateTime dateTime,
 Timestamp.Precision precision)

Initializes a Timestamp object with the given datetime and precision.

Method Details

fromHL7

public static Timestamp fromHL7(String s)

Creates a Timestamp object from the given string.

Parameters:

s - String of the pattern YYYY[MM[DD[HH[MM[SS[.S[S[S[S]]]]]]]]][+/-ZZZZ]. Milliseconds will be ignored.

Returns:

a Timestamp object, or null if the parameter is null or empty.

toHL7

public static String toHL7(Timestamp timestamp)

Returns a HL7 representation of the given timestamp, considering the precision.

Parameters:

timestamp - Timestamp object, can be null.

Returns:

HL7 representation of the timestamp, or null if the parameter is null.

toHL7

public String toHL7()

setDateTime

public void setDateTime(ZonedDateTime dateTime)

getPrecision

public Timestamp.Precision getPrecision()

now

public static Timestamp now()

Returns:

a Timestamp with the current date-time in second precision.

equals

public boolean equals(Object o)

Two HL7 timestamps are equal when they have the same values in the relevant fields (i.e. in the ones covered by the precision).

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

getDateTime

public ZonedDateTime getDateTime()

Timestamp.

setPrecision

public void setPrecision(Timestamp.Precision precision)

Precision of the timestamp (smallest present element, e.g. YEAR for "1980").
