Summary: configuration for OnlyOneReturn

Initial Comment:
Hi all,


I assume this rule is here to make code more readable, but in some case it's not usefull.
For exemple, for auto-generated equals and hashCode methods within eclipse, you break 5 times the rule OnlyOneReturn (i.e example)
but you are not going to read them !

So, may the OnlyOneReturn rule be configurable?
I was thinking of let user give a list of method not to check.
What do you think about it?

example generated by Eclipse :
public class TestEq
{
    String str = "test";

    @Override
    public int hashCode()
    {
        final int prime = 31;
        int result = 1;
        result = prime * result + ((str == null) ? 0 : str.hashCode());
        return result;
    }

    @Override
    public boolean equals(Object obj)
    {
        if (this == obj)
        {
            return true;
        }
        if (obj == null)
        {
            return false;
        }
        if (getClass() != obj.getClass())
        {
            return false;
        }
        TestEq other = (TestEq) obj;
        if (str == null)
        {
            if (other.str != null)
            {
                return false;
            }
        }
        else if (!str.equals(other.str))
        {
            return false;
        }
        return true;
    }
}
