public class TimedOperationService
extends GenericService

A TimedOperationService is a subclass of GenericService that generally performs a single function or request. This contains convenient properties for keeping statistics about the function: handledRequestCount and totalRequestHandlingTime. These statistics are useful for Services that provide a single specific function, such as a network request handler.

Another property, keepingStatistics, is settable by the configuration and can be used to turn off statistics monitoring to improve performance.

Subclasses of this class are responsible for calling notifyHandledRequest to update the statistics, and should respect the keepingStatistics flag.

TimedOperationService

public TimedOperationService()

Constructs a blank new TimedOperationService

Method Detail

setKeepingStatistics

public void setKeepingStatistics(boolean pKeepingStatistics)

Sets the flag indicating whether this should be keeping statistics or not.

isKeepingStatistics

public boolean isKeepingStatistics()

Returns the flag indicating whether this should be keeping statistics or not.

resetStatistics

public void resetStatistics()

Resets all statistics

getRequestStartTime

public long getRequestStartTime()

Returns the current time if statistics are being kept, 0 if not

notifyHandledRequest
