org.nlogo.api
Interface ClassManager

All Known Implementing Classes:

DefaultClassManager

public interface ClassManager

Interface specifies the main class of a NetLogo extension. All NetLogo extensions must include a class that implements this interface. Registers primitives with NetLogo and handles extension initialization and deconstruction.

For example:

 public class FibonacciExtension extends org.nlogo.api.DefaultClassManager
 {
     public void load(org.nlogo.api.PrimitiveManager primManager)
     {
         primManager.addPrimitive("first-n-fibs", new Fibonacci());
     }
 }
 

Method Summary

void	load(PrimitiveManager primManager) Loads the primitives in the extension.
void	runOnce(ExtensionManager em) Initializes the extension.
void	unload() Cleans up the extension.

Method Detail

runOnce

public void runOnce(ExtensionManager em)
             throws ExtensionException

Initializes the extension. This is called once per NetLogo instance.

Throws:

ExtensionException

load

public void load(PrimitiveManager primManager)
          throws ExtensionException

Loads the primitives in the extension. This is called each time a model that uses this extension is compiled.

Parameters:

primManager - The manager to transport the primitives to NetLogo

Throws:

ExtensionException

unload

public void unload()
            throws ExtensionException

Cleans up the extension. This is called once before load is called.

Throws:

ExtensionException
