Class SandboxedScriptEngine

java.lang.Object

org.rhq.scripting.util.SandboxedScriptEngine

All Implemented Interfaces:

ScriptEngine

public class SandboxedScriptEngine
extends Object
implements ScriptEngine

This is a decorator class for any other ScriptEngine implementation that runs any of the eval methods with the defined set of Permissions.

For the permissions to have any effect, a SecurityManager has to be installed in the current VM.

This class is provided in hopes that it can help provide security to script engines that do not directly implement some kind of security measures.
