getLastAccessedTime()

virtual time_point apache::geode::client::CacheStatistics::getLastAccessedTime ( ) const

virtual

For an entry, returns the last time it was accessed via Region.get.

For a region, returns the last time any of its entries or the entries of its subregions were accessed with Region.get. Any modifications will also update the lastAccessedTime, so lastAccessedTime is always >= lastModifiedTime. The lastAccessedTime on a region is propagated upward to parent regions, transitively, to the the root region.

Returns

the last access time of the region or the entry's value; returns std::chrono::system_clock epoch if the entry is invalid or the modification time is uninitialized.

getLastModifiedTime

getLastModifiedTime()

virtual time_point apache::geode::client::CacheStatistics::getLastModifiedTime ( ) const

virtual

For an entry, returns the time that the entry's value was last modified.

For a region, returns the last time any of the region's entries' values or the values in subregions' entries were modified. The modification may have been initiated locally, or it may have been an update distributed from another cache. It may also have been a new value provided by a loader. The modification time on a region is propagated upward to parent regions, transitively, to the root region.

Entry and subregion creation will update the modification time on a region, but destroy, destroyRegion, invalidate, and invalidateRegion do not update the modification time.

Returns

the last modification time of the region or the entry; returns std::chrono::system_clock epoch if the entry is invalid or the modification time is uninitialized.
