Examples of org.apache.excalibur.instrument.Instrumentable

org.apache.excalibur.instrument.Instrumentable
The Instrumentable interface is to mark objects that can be sampled by an InstrumentManager. The getInstruments method may or may not be called depending on whether or not the ComponentLocator used to create the Component supports Instrumentables. In most cases, an instrumentable object should always create its internal Instruments and make use of them as if instrument data were being collected. The Instruments are optimized so as not to reduce performance when they are not being used. @author Leif Mortenson @version CVS $Revision: 1.2 $ $Date: 2003/02/20 17:07:55 $ @since 4.1
