Method Detail

getExpiry

int getExpiry()

Returns the expiration time of the entity.

The Couchbase format for expiration time is: - for TTL < 31 days (<= 30 * 24 * 60 * 60): expressed as a TTL in seconds - for TTL > 30 days: expressed as Unix UTC time of expiry (number of SECONDS since the Epoch)

Returns:

the expiration time in correct Couchbase format.

isTouchOnRead

boolean isTouchOnRead()

Flag for using getAndTouch operations for reads, resetting the expiration (if one was set) when the entity is directly read (eg. findOne, findById).

Returns:

true if a direct read of the document should trigger a touch, resetting its expiration timer.
