Class LeaseInfo

java.lang.Object

com.netflix.appinfo.LeaseInfo

public class LeaseInfo
extends java.lang.Object

Represents the lease information with Eureka.

Eureka decides to remove the instance out of its view depending on the duration that is set in EurekaInstanceConfig.getLeaseExpirationDurationInSeconds() which is held in this lease. The lease also tracks the last time it was renewed.

LeaseInfo

public LeaseInfo(int renewalIntervalInSecs,
                 int durationInSecs,
                 long registrationTimestamp,
                 java.lang.Long lastRenewalTimestamp,

                 long serviceUpTimestamp)

TODO: note about renewalTimestamp legacy: The previous change to use Jackson ser/deser changed the field name for lastRenewalTimestamp to renewalTimestamp for serialization, which causes an incompatibility with the jacksonNG codec when the server returns data with field renewalTimestamp and jacksonNG expects lastRenewalTimestamp. Remove this legacy field from client code in a few releases (once servers are updated to a release that generates json with the correct lastRenewalTimestamp).

Method Detail

getRegistrationTimestamp

public long getRegistrationTimestamp()

Returns the registration timestamp.

Returns:

time in milliseconds since epoch.

getRenewalTimestamp

public long getRenewalTimestamp()

Returns the last renewal timestamp of lease.

getEvictionTimestamp

public long getEvictionTimestamp()

Returns the de-registration timestamp.

Returns:

time in milliseconds since epoch.

getServiceUpTimestamp

public long getServiceUpTimestamp()

Returns the service UP timestamp.

Returns:

time in milliseconds since epoch.

getRenewalIntervalInSecs

public int getRenewalIntervalInSecs()

Returns client specified setting for renew interval.

Returns:

time in milliseconds since epoch.

getDurationInSecs

public int getDurationInSecs()

Returns client specified setting for eviction (e.g. how long to wait w/o renewal event)

Returns:

time in milliseconds since epoch.
