Class SimpleSystemContext

java.lang.Object
  autohit.server.SimpleSystemContext

All Implemented Interfaces:

SystemContext

public class SimpleSystemContext

extends java.lang.Object

implements SystemContext

A simple system context for a server or invoker.

 It includes:
 a basic log manager (@see #logger)
 a root logger
 a basic properties set (@see #prop)
 a single script SIM compiler (@see #compiler)
 a universe factory (@see #uf)
 a LOCAL universe server
 a Kernel (uninitialized!)
 a root loader (uninitialized!)
 

It requires the root property be set.

Constructor Detail

SimpleSystemContext

public SimpleSystemContext()
                    throws java.lang.Exception

Default Constructor.

Method Detail

init

public void init(org.apache.commons.collections.ExtendedProperties props)
          throws java.lang.Exception

Properties constructor. Give it a full path to the properties file.

Specified by:

init in interface SystemContext

Parameters:

props - properties set

Throws:

java.lang.Exception

loadProperties

public void loadProperties(org.apache.commons.collections.ExtendedProperties props)
                    throws java.lang.Exception

Load properties. It will delete any previously loaded properties.

Specified by:

loadProperties in interface SystemContext

Parameters:

props - a properties set

Throws:

java.lang.Exception

getUniverse

public Universe getUniverse()

Get the default universe

Specified by:

getUniverse in interface SystemContext

Returns:

Universe service interface

getUniverse

public Universe getUniverse(java.lang.String handle)

Get a universe service by handle. This implementation ignores the handle and returns the only universe we have.

Specified by:

getUniverse in interface SystemContext

Parameters:

handle - handle to the universe

Returns:

Universe service interface

getCompiler

public XmlCompiler getCompiler()

Get the XML compiler

Specified by:

getCompiler in interface SystemContext

Returns:

XmlCompiler base class

getRootLogger

public AutohitLogInjectorWrapper getRootLogger()

Get a reference to a generic, root log injector

Specified by:

getRootLogger in interface SystemContext

Returns:

XmlCompiler base class

getEventDispatcher

public Injector getEventDispatcher()

Cheat. The logger will be our even dispacter

Specified by:

getEventDispatcher in interface SystemContext

Returns:

Injector reference

getPropertiesSet

public org.apache.commons.collections.ExtendedProperties getPropertiesSet()

Get properties set

Specified by:

getPropertiesSet in interface SystemContext

Returns:

reference to the properties set

getLogManager

public AutohitBasicLogManager getLogManager()

Get log manager reference

Specified by:

getLogManager in interface SystemContext

Returns:

reference to the properties set

getKernel

public Kernel getKernel()

Get the Kernel

Specified by:

getKernel in interface SystemContext

Returns:

reference to the kernel

getLoader

public VMLoader getLoader()

Get the VM Loader

Specified by:

getLoader in interface SystemContext

Returns:

reference to the kernel

getCommandRegistry

public CommandRegistry getCommandRegistry()

Get the command registry as a properties set. It is not cached. this implementation will always return the default set.

Specified by:

getCommandRegistry in interface SystemContext

Returns:

properties set representing the registry. it will return null if it cannot be loaded

uniqueInteger

public int uniqueInteger()

Unique number

Specified by:

uniqueInteger in interface SystemContext

Returns:

an integer number unique (at least) to this Context

Specified by:

getInvokerProperties in interface SystemContext

Returns:

reference to the invoker properties set
