Class CPUExecHandler

java.lang.Object
  org.rioproject.system.measurable.cpu.CPUExecHandler

All Implemented Interfaces:

MeasurableMonitor<CpuUtilization>

Direct Known Subclasses:

MacTopOutputParser, MpstatOutputParser

public abstract class CPUExecHandler
extends Object
implements MeasurableMonitor<CpuUtilization>
