Constructor Detail

ZonelessTimestamp

public ZonelessTimestamp()

Constructs a ZonelessTimestamp.

ZonelessTimestamp

public ZonelessTimestamp(int precision)

Constructs a ZonelessTimestamp with precision.

The precision is the number of digits to the right of the decimal point in the seconds value. For example, a TIMESTAMP(3) has a precision to milliseconds.

Parameters:

precision - Number of digits of precision

Method Detail

toJdbcObject

public Object toJdbcObject()

Description copied from class: ZonelessDatetime

Returns this datetime as a Jdbc object

Specified by:

toJdbcObject in class ZonelessDatetime

toString

public String toString()

Converts this ZonelessTimestamp to a java.sql.Timestamp and formats it via the toString() method of that class.

Note: Jdbc formatting always includes a decimal point and at least one digit of milliseconds precision. Trailing zeros, except for the first one after the decimal point, do not appear in the output.

Overrides:

toString in class Object

Returns:

the formatted time string

toString

public String toString(String format)

Formats this ZonelessTimestamp via a SimpleDateFormat. This method does not display milliseconds precision.

Parameters:

format - format string, as required by SimpleDateFormat

Returns:

the formatted timestamp string

parse

public static ZonelessTimestamp parse(String s)

Parses a string as a ZonelessTimestamp.

This method's parsing is strict and may parse fractional seconds (as opposed to just milliseconds.)

Parameters:

s - a string representing a time in ISO format, i.e. according to the SimpleDateFormat string "yyyy-MM-dd HH:mm:ss"

Returns:

the parsed time, or null if parsing failed

parse

public static ZonelessTimestamp parse(String s,
                      String format)

Parses a string as a ZonelessTimestamp using a given format string.

This method's parsing is strict and may parse fractional seconds (as opposed to just milliseconds.)

Parameters:

s - a string representing a time in ISO format, i.e. according to the SimpleDateFormat string "yyyy-MM-dd HH:mm:ss"

format - Format string as per SimpleDateFormat

Returns:

the parsed timestamp, or null if parsing failed

getTempTimestamp

protected Timestamp getTempTimestamp(long value)

Gets a temporary Timestamp object. The same object is returned every time.
