DestroyItem in ViewPager?

[Saathwik]

When is the following method called?

void destroyItem (ViewGroup container,
int position,
Object object)


In ViewPager i set my adapter as follows

myViewPagerAdapter = new MyViewPagerAdapter();
viewPager.setAdapter(myViewPagerAdapter);

This is my MyViewPagerAdapter class

public class MyViewPagerAdapter extends PagerAdapter {
private LayoutInflater layoutInflater;

public MyViewPagerAdapter() {
}

@override
public Object instantiateItem(ViewGroup container, int position) {
layoutInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);

View view = layoutInflater.inflate(layouts[position], container, false);
container.addView(view);

return view;
}

@override
public int getCount() {
return layouts.length;
}

@override
public boolean isViewFromObject(View view, Object obj) {
return view == obj;
}


@override
public void destroyItem(ViewGroup container, int position, Object object) {
View view = (View) object;
container.removeView(view);
}
}

What happens when i call the empty contructor in MyViewPagerAdapter? Which methods are called?
