Description copied from interface: InterfaceMonitor

called after the given method on the given object with the given arguments has been executed. Of the last two arguments, one is always null while the other contains a value. Note that this method is synchronously called before the return value (or the exception to be thrown) is passed to the caller of the proxy object.

Specified by:

methodInvoked in interface InterfaceMonitor

Overrides:

methodInvoked in class InterfaceMonitor.Adapter

Parameters:

obj - the original object that the given method was invoked on

m - the method that was executed on the given object

args - the arguments that were used for the given method call (may be null)

timeTaken - the time it took to execute the given method in milliseconds

returnValue - the value returned by the given method call (if no exception was thrown; otherwise null)

t - contains the exception thrown by the given method call (if any); if the Throwable is null, the returnValue is not and vice versa.

getProfileData

public Map<Method,DataPoint> getProfileData()

provides performance data over the wrapped instance; the DataPoint is based on the time each call took.
