Constructor Detail

LwwTime

public LwwTime(long timestamp,
               java.lang.String originDc)

Method Detail

apply

public static LwwTime apply(long timestamp,
                            java.lang.String originDc)

unapply

public static scala.Option<scala.Tuple2<java.lang.Object,java.lang.String>> unapply(LwwTime x$0)

timestamp

public long timestamp()

originDc

public java.lang.String originDc()

increase

public LwwTime increase(long t,
                        java.lang.String dc)

Create a new LwwTime that has a timestamp that is max of the given timestamp and previous timestamp + 1, i.e. monotonically increasing.

Parameters:

t - (undocumented)

dc - (undocumented)

Returns:

(undocumented)

isAfter

public boolean isAfter(LwwTime other)

Compare this LwwTime with the other. Greatest timestamp wins. If both timestamps are equal the dc identifiers are compared and the one sorted first in alphanumeric order wins.

Parameters:

other - (undocumented)

Returns:

(undocumented)
