jmt.measurement
Class AbstractMeasurementMethod
java.lang.Object
|
+--jmt.measurement.AbstractMeasurementMethod
- All Implemented Interfaces:
- MeasurementMethod
- Direct Known Subclasses:
- AbstractApplicationMeasurementMethod
- public abstract class AbstractMeasurementMethod
- extends java.lang.Object
- implements MeasurementMethod
Convenience abstract implementation of the MeasurementMethod to
be subclassed.
It also implements caching of results of measurement methods. The cache
can be enabled or disabled by the current implementations of this abstract
class by overriding the isCacheable method. By
default the caching is deactivated.
Note: The caching uses a soft-reference to store the object the result
was measured of.
