ProfileManager

public ProfileManager(io.ebean.config.AutoTuneConfig config,
 io.ebeaninternal.api.SpiEbeanServer server)

Method Details

isProfileRequest

public boolean isProfileRequest(io.ebean.bean.ObjectGraphNode origin,
 io.ebeaninternal.api.SpiQuery<?> query)

Specified by:

isProfileRequest in interface io.ebeaninternal.server.autotune.ProfilingListener

collectQueryInfo

public void collectQueryInfo(io.ebean.bean.ObjectGraphNode node,
 long beans,
 long micros)

Gather query execution statistics. This could either be the originating query in which case the parentNode will be null, or a lazy loading query resulting from traversal of the object graph.

Specified by:

collectQueryInfo in interface io.ebeaninternal.server.autotune.ProfilingListener

collectNodeUsage

public void collectNodeUsage(io.ebean.bean.NodeUsageCollector.State usageCollector)

Collect usage statistics from a node in the object graph.

This is sent to use from a EntityBeanIntercept when the finalise method is called on the bean.

Specified by:

collectNodeUsage in interface io.ebean.bean.NodeUsageListener

profilingCollection

public AutoTuneCollection profilingCollection(boolean reset)

Collect all the profiling information.
