SuspendableScriptExecutor

[kozyatinskiy1, 2014/10/22 13:53:03]

Done.

+public:
+    SuspendableScriptRunner(LocalFrame*, int worldID, const Vector<ScriptSourceCode>& sources, int extensionGroup, bool userGesture, PassOwnPtr<ScriptExecutionCallback>);
+    virtual ~SuspendableScriptRunner();
+
+    void run();

Can we move this into constructor? We always want to run it immediately after
creation anyway.

[kozyatinskiy1, 2014/10/22 13:53:03]

No, we can't call delete this in class cstor.

+    virtual void resume() override;
+
+    virtual void contextDestroyed() override;
+
+private:
+    void executeAndDestroySelf();
+
+    LocalFrame* m_frame;
+    int m_worldID;
+    Vector<ScriptSourceCode> m_sources;
+    int m_extensionGroup;
+    bool m_userGesture;
+    OwnPtr<ScriptExecutionCallback> m_client;
+};
