Is it possible to execute a method once before a single but parameterized test?

So I have Selenium tests that use TestNG to test UI, but right now I'm struggling with a problem : how can I execute a specific method only once before a parameterized test ? I have a parameterized test like this :

@Test(dataProvider="myProvider")
public void testMyThingToTest() {
   // Things to test in here
}

My parameterized test works great and gets executed once for each parameter given. Now I have a initialization that is common to all my instances of my parameterized test, so I would like it to be ran only once, not before every instance of the parameterized test... If I do something like using @BeforeTest or @BeforeMethod : 

@BeforeMethod
public void initialization() {
    // The initialization phase here...
}

The init method is run before every test... any idea how to achieve that ? The purpose of this is to avoid doing some overwhelming job for each parameter, because my initialization takes something like 30 sec, and I have 7-8 parameters for my test, so I would rather have an initialization time of 30sec * 1 rather than 30sec * 8

call function in dataprovider

@DataProvider
public Object[][] FeederOfResponseCodes()
{
        initialization();

        return new Object[][]
        {
        };
}

Try 

@BeforeSuite
public void initialization() {
    // Init suite
}

If you want other scenarios. Pick annotation with following priority: @BeforeSuite > @BeforeTest > @BeforeClass > @BeforeMethod

If I understood correctly, you want to execute a method only once for all tests that are in you test class.

TestNG provide an annotation for that @BeforeClass: Annotates methods that will be run before the first method on the current test class is run.

You can find an example at http://java.dzone.com/articles/testng-beforeclass-annotation
