Class Executive

java.lang.Object
  org.jeospace.simulation.Executive

All Implemented Interfaces:

AtlasListener, java.util.EventListener, ProfileListener

public class Executive

extends java.lang.Object

implements ProfileListener, AtlasListener

The Executive is the simulation configuration manager.

The primary functions of the Executive are:

• instantiates core configuration (systemProfile)
• demand loads/unloads user configurations (userProfile)
• manages ongoing event driven changes to the user configuration

The main class handles the creation and manipulation of the core configuration as defined by the 'systemProfile'. This includes the creation of the root SystemNode and the loading of the base set of geometry, etc.

After establishing the base simulation platform, The executive is available to support a user configuration defined by the 'userProfile'. The executive manages the event driven configuration changes to the configuration objects - the user profile and the user profile's collection of atlases.

Subordinates of the Executive, the ChronManager & the SimManager handle the time base of the simulation and the visualization and navigation portions of the simulation respectively.
