Examples of org.rhq.core.system.ProcessExecution

org.rhq.core.system.ProcessExecution
Provides information on what process to execute and how to execute it.
Agent plugin developers should also see the ProcessExecutionUtility class in the plugin-api module, which provides handy methods for creating ProcessExecutions. @author John Mazzitelli @author Ian Springer @author Jay Shaughnessy @see org.rhq.core.system.JavaSystemInfo#executeProcess(ProcessExecution)
