maximumDuration property

double get maximumDuration

The maximum time (in seconds) an observation remains in the application.

Observations older than the specified maximum duration are removed from the local data cache.

The default value is 0.0 seconds which means the maximum duration is disabled and duration is not used to purge observations from the local data cache. Setting maximum duration to anything else below 1.0 defaults to 1.0.
