Class SystemStateServiceImpl

java.lang.Object
  org.ow2.petals.system.systemstate.SystemStateServiceImpl

All Implemented Interfaces:

SystemStateService

public class SystemStateServiceImpl
extends java.lang.Object
implements SystemStateService

Creates and reads state files for components, shared libs and service assemblies. State files are text files that keep the state of JBI entities to allow state retreval after Petals system shutdown or crash.
