java.lang.Object
    |
    +----cornell.slk.jos.manager.SubsystemManager
public class SubsystemManager
extends java.lang.Object
implements ISubsystemManager
SubsystemManager is reponsible for loading and unloading subsystems tasks. It maintains two kinds of subsystems: the standard ones, which are loaded at JOS initialization, and the non-standard ones, loaded through HTTP using the SubsystemLoader servlet.

Constructor Summary
 SubsystemManager()
 
 

Method Summary
void  loadStandardSubsystems(java.lang.String configFile, java.lang.String binPath, java.util.Hashtable commandLineArgs)
loadStandardSubsystems takes a configuration file, loads all the subsystems listed in the configuration file, and puts them in the standard tables.
Subsystem  loadSubsystem(SubsystemInfo si)
loadSubsystem launches a new subsystem task.
static void  main(java.lang.String[] args)
 
SubsystemInfo  readConfigFile(java.lang.String configFile)
readConfigFile reads the properties of a subsystem from a configuration file into a SubsystemInfo data structure.
void  unloadStandardSubsystems()
unloadStandardSubsystems unloads all the subsystems according to the stopStandardSubsystemsVector.
void  unloadSubsystem(Subsystem s)
unloadSubsystem terminates the subsystem task.

Method Detail

loadStandardSubsystems

public void loadStandardSubsystems(java.lang.String configFile,
                                   java.lang.String binPath,
                                   java.util.Hashtable commandLineArgs) throws SubsystemException
loadStandardSubsystems takes a configuration file, loads all the subsystems listed in the configuration file, and puts them in the standard tables. The key/value pairs in commandLineArgs is appended to the parameter hashtables of *every* subsystem.

unloadStandardSubsystems

public void unloadStandardSubsystems()
unloadStandardSubsystems unloads all the subsystems according to the stopStandardSubsystemsVector.

readConfigFile reads the properties of a subsystem from a configuration file into a SubsystemInfo data structure.
Implements:
readConfigFile in interface ISubsystemManager

loadSubsystem

public Subsystem loadSubsystem(SubsystemInfo si) throws SubsystemException
loadSubsystem launches a new subsystem task.
Implements:
loadSubsystem in interface ISubsystemManager

unloadSubsystem
