SQL : BeanSerializer with hashCode + equals + toString

[Timo Westkämper]

* equals(): based on class and primary key
* hashCode(): return primary keys's hash code
* toString(): Something like "Class#pk" for single column PKs, and Class#<col1,col2,col3> for multiple columns.

Attached a patch to output <null> on toString() to null pk's, not invoking the super.toString()

[Timo Westkämper (timo-westkamper)]

The patch didn't work, but I commited something similar :

patch :

    @Override
    public String toString() {
        return "Multikey#" + id == null ? "<null>" : "\"" + id + "\""+ "; + id2 == null ? "<null>" : "\"" + id2 + "\""+ "; + id3 == null ? "<null>" : "\"" + id3 + "\"";
    }

commited :

    @Override
    public String toString() {
        return "Multikey#" + id+ ";" + id2+ ";" + id3;
    }

Way better.
When I first looked at the serializer code, I thought you had quoted each value, that's why I added them...
The way it is now, it's perfect.
