Method Detail

getTimestamp

public final long getTimestamp()

Returns the time at which this Value object was created. We use this timestamp to determine how long it has been since a region operation has taken place. That is, while validating if we see that the value of an entry only recently changed, we may briefly pause to allow the change to propagate.

Returns the timestamp in the same format as those in the GemFire log files.
