Method Detail

isProfileRequest

public boolean isProfileRequest(ObjectGraphNode origin,
                                SpiQuery<?> query)

Description copied from interface: ProfilingListener

Return true if this request should be profiled (based on the profiling ratio and collection count for this origin).

Specified by:

isProfileRequest in interface ProfilingListener

collectQueryInfo

public void collectQueryInfo(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 ProfilingListener

Parameters:

node - the node relative to the origin point

beans - the number of beans loaded by the query

micros - the query execution in microseconds

collectNodeUsage

public void collectNodeUsage(NodeUsageCollector 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 NodeUsageListener

profilingCollection

public AutoTuneCollection profilingCollection(boolean reset)

Collect all the profiling information.
