Class SessionProfilerAdapter

java.lang.Object

org.eclipse.persistence.sessions.SessionProfilerAdapter

All Implemented Interfaces:

SessionProfiler

Direct Known Subclasses:

PerformanceProfiler

public abstract class SessionProfilerAdapter
extends Object
implements SessionProfiler

Adapter class for SessionProfiler interface. This class should be subclasses for profilers to avoid backward compatiblity issues with future releases when additional API is added to the interface.

Method Detail

endOperationProfile

public void endOperationProfile(String operationName)

INTERNAL: End the operation timing.

Specified by:

endOperationProfile in interface SessionProfiler

endOperationProfile

public void endOperationProfile(String operationName,
                                DatabaseQuery query,
                                int weight)

INTERNAL: End the operation timing.

Specified by:

endOperationProfile in interface SessionProfiler

profileExecutionOfQuery

public Object profileExecutionOfQuery(DatabaseQuery query,
                                      Record row,
                                      AbstractSession session)

INTERNAL: Finish a profile operation if profiling. This assumes the start operation proceeds on the stack. The session must be passed to allow units of work etc. to share their parents profiler.

Specified by:

profileExecutionOfQuery in interface SessionProfiler

Returns:

the execution result of the query.

setSession

public void setSession(Session session)

INTERNAL: Set the session.

Specified by:

setSession in interface SessionProfiler

startOperationProfile

public void startOperationProfile(String operationName)

INTERNAL: Start the operation timing.

Specified by:

startOperationProfile in interface SessionProfiler

startOperationProfile

public void startOperationProfile(String operationName,
                                  DatabaseQuery query,

INTERNAL: Start the operation timing.

Specified by:

startOperationProfile in interface SessionProfiler

update

public void update(String operationName,
                   Object value)

INTERNAL: Update the value of the State sensor.(DMS)

Specified by:

                     DatabaseQuery query,
                     AbstractSession session)

INTERNAL: Increase DMS Event sensor occurrence.(DMS)

Specified by:

occurred in interface SessionProfiler

setProfileWeight

public void setProfileWeight(int weight)

INTERNAL: Set DMS sensor weight(DMS)

Specified by:
