Mr. Sempere,
NetLogo uses Java classes to run the simulation. These Java classes adhere
to interfaces (scala's terminology calls them "traits") found in the
org.nlogo.api
<https://ccl.northwestern.edu/netlogo/docs/scaladoc/org/nlogo/api/index.html>
package. The easiest way to inspect the world is to get the world (using
workspace.world()) and to access objects using methods on the world
interface.
<https://ccl.northwestern.edu/netlogo/docs/scaladoc/org/nlogo/api/World.html>
A few words of caution about using world directly:
- Although world has more methods than are found on the interface linked
above, we generally recommend not using those methods as they may be
changed between NetLogo releases. If you include the NetLogo jar with your
program (and so have control over when the version changes) this is less of
an issue.
- World and its various members are *not* thread-safe. You should not
attempt to access them if a call to workspace.command or workspace.report
is in progress.
- Directly altering any values on world or its various members is very
likely to break reproducibility.
Hope that helps! Please feel free to post any follow-up questions you have
on this topic.
Thanks,
Robert
I have developed a java program that invokes a netlogo written agent model.
