Statistics

org.hibernate.stat.Statistics
Known Indirect Subclasses

Class Overview

Statistics for a particular SessionFactory. Beware of milliseconds metrics, they are depdendent of the JVM precision: you may then encounter a 10 ms approximation dending on you OS platform. Please refer to the JVM documentation for more information.
