Hello,
how can I reuse an AsyncCallback Class? Is there any concept?
For example, I have the following AsyncCallback defined in a GUI
class:
AsyncCallback<LoginResult> callback = new
AsyncCallback<LoginResult>()
{
public void onFailure( Throwable caught )
{
// Show error message
}
public void onSuccess( LoginResult result )
{
// Show success message
}
};
loginService.loginUser(user, password, callback);
And I want to use the same functionality in another GUI class, how can
I accomplish this? I have a lot of code duplication and I want to
reduce it. In the end, I'd like to have something like:
LoginResult result = LoginUtil.loginUser(user, password)
if (result == error) doSomething;
if(result == success) doSomething;
Thanks in advance
