At which point in the lifecycle does GetConnectionInterface get called?

Question

I have this method on a webpart:

private IFilterData _filterData = null;

[ConnectionConsumer("Filter Data Consumer")]
public void GetConnectionInterface(IFilterData filterData)
{
    _filterData = filterData;
}

Now, before I can call upon _filterData, I need to know when i can expect it to not be null. When is this?!

Without knowing this, the best I can do is stuff all of my _filterWebpart dependant code into the last lines of OnPreRender and hope for the best.

According to this document, it looks like Load.
