How to access the map returned by IParameterValues::getParameterValues()?
- by Hua
I declared a command and a commandParameter for this command. I specified the "values" of this commandParameter as a class implemented by myself. The implementation of this class is below,
public class ParameterValues implements IParameterValues {
@Override
public Map<String, Double> getParameterValues() {
// TODO Auto-generated method stub
Map<String, Double> values = new HashMap<String, Double>(2);
values.put("testParam", 1.1239);
values.put("AnotherTest", 4.1239);
return values;
}
}
The implementation of the handler of this command is blow,
public class testHandler extends AbstractHandler implements IHandler {
private static String PARAMETER_ID = "my.parameter1";
@Override
public Object execute(ExecutionEvent event) throws ExecutionException {
String value = event.getParameter(PARAMETER_ID);
MessageDialog.openInformation(HandlerUtil.getActiveShell(event),
"Test", "Parameter ID: " + PARAMETER_ID + "\nValue: " + value);
return null;
}
}
Now, I contribute the command to a menu,
<menuContribution
locationURI="menu:org.eclipse.ui.main.menu">
<menu
id="my.edit"
label="Edit">
<command
commandId="myCommand.test"
label="Test1">
<parameter
name="my.parameter1"
value="testParam">
</parameter>
</command>
Since I specified a "values" class for the commandParater, I expect when the menu is clicked, this code line "String value = event.getParameter(PARAMETER_ID);" in the handler class returns 1.1239 instead of "testParam".
But, I still see that code line returns "testParam".
What's the problem? How could I access the map returned by getParameterValues()?
By the way, following menu declaration still works even I don't define "ppp" in the map.
<menuContribution
locationURI="menu:org.eclipse.ui.main.menu">
<menu
id="my.edit"
label="Edit">
<command
commandId="myCommand.test"
label="Test1">
<parameter
name="my.parameter1"
value="ppp">
</parameter>
</command>
Thanks!
