```
public class ImportAccessorAction
extends javax.swing.AbstractAction
```
An Action to import an Internet of Things (IoT) accessor.
This action presents a dialog box that permits specifying a URL or local directory. If the URL or local directory contains a file named index.json, then it presents a list of the options given in that file, which it assumes are all accessors. To manually specify a particular accessor on the local file system, you can browse to its directory, but then you have to manually type in the file name of the accessor.

This package is optional. To add the "Import Accessor" menu choice to the GraphEditor, add the following to the configuration:
```
   <property name="_importActionClassNames"
   class="ptolemy.data.expr.Parameter"
   value="{"ptolemy.vergil.basic.imprt.accessor.ImportAccessorAction"}"/>
   
```
BasicGraphFrame checks for this parameter and adds the "Import Accessor" menu choice if the class named by that parameter exists.

The $PTII/ptolemy/configs/defaultFullConfiguration.xml file already has this parameter. The ptiny configuration does not have this parameter so that we have a smaller download.
