Class Landscape
java.lang.Objectorg.mrd.models.cagn.Landscape
- public class Landscape
- extends java.lang.Object
Landscape Encapsulates much of the Internal Datastructure management of a spatial simulation. It takes care of traking agents that are dead and need to be added or removed from the simulation landscape. It is composed of Three primary data structures: 1.) Agent Grid - used to track nieghorhood relationships 2.) Resource Grid - represents available resources in an area 3.) Agent List - A randomizable or sortable list that is iterated over to update the agents. There is one secondary datastructure, a birth queue, this store new agents that need to be added to the model at the end of a iteration.

agentGrid
protected Object2DGrid agentGrid
- Grid that holds the Agents.
habitatGrid
protected Object2DGrid habitatGrid
- Grid that holds the Habitat Resources
agents
protected java.util.ArrayList agents
- A list of all the agents. Convenient for any method that
iterates through a list of agents. A least one list like this is common
to most simulations. See below for examples of its use.
birthQueue
protected java.util.Vector birthQueue
- This queue holds dispersed agents that need to be added to the simulation at the end
of the iteration.
reaperQueue
protected java.util.Vector reaperQueue
- This queue holds agensts that failed to disperse that need to be removed from the simulation.
pool
protected org.apache.commons.pool.ObjectPool pool
- Holds value of property model.
