java - 如何通过代码将参数传递给eclipse rcp应用程序中的命令？

Question

我使用下面的代码来运行通过 org.eclipse.ui.commands 添加的命令:

IServiceLocator serviceLocator = PlatformUI.getWorkbench();
ICommandService commandService = (ICommandService) serviceLocator.getService(ICommandService.class);

try  {
        Command command = commandService.getCommand("my_command_id");
        command.executeWithChecks(new ExecutionEvent());

    } catch (ExecutionException ex1) {

    } catch (NotDefinedException ex2){

    } catch(NotEnabledException ex3){

    } catch(NotHandledException ex4){

    }

这工作正常，但我想向该命令传递一个参数。我有接受参数的机制，但如何通过代码传递它？

想通了!执行以下操作来执行相同的操作:

IServiceLocator serviceLocator = PlatformUI.getWorkbench();
ICommandService commandService = (ICommandService) serviceLocator.getService(ICommandService.class);

try  { 
        Command command = commandService.getCommand("my_command_id");
        Map<String, String> map = new HashMap<String, String>();
        map.put("param_name", "param_value");
        /*more parameter's can be added to Map and passed*/
        command.executeWithChecks(new ExecutionEvent(null, map, null, null));

    } catch (ExecutionException e1) {

    } catch (NotDefinedException e2){

    } catch(NotEnabledException e3){

    } catch(NotHandledException e4){

    }
