Property Documentation

LastAccessedTime

System:: UInt32 Apache::Geode::Client::CacheStatistics::LastAccessedTime

get

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 greater than or equal to LastModifiedTime. The LastAccessedTime on a region is propagated upward to parent regions, transitively, to the the root region.

The number is expressed as the number of milliseconds since January 1, 1970. The granularity may be as coarse as 100ms, so the accuracy may be off by up to 50ms.

Returns

the last access time of the region or the entry's value; returns 0 if entry is invalid or access time is uninitialized.

LastModifiedTime

System:: UInt32 Apache::Geode::Client::CacheStatistics::LastModifiedTime

get

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.

The number is expressed as the number of milliseconds since January 1, 1970. The granularity may be as coarse as 100ms, so the accuracy may be off by up to 50ms.

Entry and subregion creation will update the modification time on a region, but Region.Destroy, Region.DestroyRegion, Region.Invalidate, and Region.InvalidateRegion do not update the modification time.

Returns

the last modification time of the region or the entry; returns 0 if the entry is invalid or the modification time is uninitialized.
