Class DisposablePyObjectAdapter

java.lang.Object

com.inductiveautomation.ignition.common.script.DisposablePyObjectAdapter

All Implemented Interfaces:

org.python.core.adapter.PyObjectAdapter

public class DisposablePyObjectAdapter
extends java.lang.Object
implements org.python.core.adapter.PyObjectAdapter

This class exists so that modules can add PyObjectAdapter to the global, static extensible adapter found at Py.getAdapter() in a way that can prevent leaking the module's classloader. The module wraps up their object adapter in this wrapper, and ensures to call dispose() when the module is shut down. This will still cause a memory leak, albeit extremely small: one adapter object per module (re-)start. This is the only way to be able to use this part of the Jython API because they don't provide for removing adapters that have been registered.
