net.openhft.chronicle.wire.AbstractTimestampLongConverter

net.openhft.chronicle.wire.NanoTimestampLongConverter

All Implemented Interfaces:

LongConverter

public class NanoTimestampLongConverter
extends AbstractTimestampLongConverter

A NanoTimestampLongConverter is an implementation of AbstractTimestampLongConverter which handles conversions between long timestamps and date-time strings. The precision of this converter is to the nanosecond. This converter is singleton, the instance can be accessed using the public field INSTANCE.

Field Detail

INSTANCE

public static final NanoTimestampLongConverter INSTANCE

The singleton instance of this converter.

Constructor Detail

NanoTimestampLongConverter

public NanoTimestampLongConverter()

Constructs a new NanoTimestampLongConverter with the default zone ID (fetched from the system property or UTC).

NanoTimestampLongConverter

public NanoTimestampLongConverter(String zoneId)

Constructs a new NanoTimestampLongConverter with the specified zone ID.

Parameters:

zoneId - the zone ID to be used for the conversion of long values

Method Detail

parseFormattedDate

protected long parseFormattedDate(ZonedDateTime value)

Parses a formatted date into a long timestamp. This implementation uses the epoch day and time of the day to compute the long timestamp.

Specified by:

parseFormattedDate in class AbstractTimestampLongConverter

Parameters:

value - The parsed formatted date (in UTC zone)

Returns:

The value as a long timestamp

parseTimestamp

protected long parseTimestamp(long value,
                              CharSequence text)

Parses a long timestamp. The provided timestamp value is converted to nanoseconds. A debug log is printed if the timestamp is in microseconds or if it's a non-zero value.

Specified by:

parseTimestamp in class AbstractTimestampLongConverter

Parameters:

value - The parsed timestamp

text - The text version of the timestamp

Returns:

The value as a long timestamp

appendFraction

protected void appendFraction(DateTimeFormatterBuilder builder)

Appends the fraction of the second to the provided DateTimeFormatterBuilder. The fraction is defined in nanoseconds and can be 0 to 9 digits long.

Specified by:

appendFraction in class AbstractTimestampLongConverter

Parameters:

builder - The builder after the initial date format has been added
