default equals again, sorry

[Jose]

I see thanks; I have to replicate the code in each factory. 

On the other way, do you think that this idiom would lead to a fewer
overhead than instantiating (x,y) points?. 

The scenario is a chain of 2D transforms (over an image for example), every
step would require a new pair to be created.

Paul, I want to compare this with a stock implementation, but I don't need
it, I only want a factory to create anonymous classes from the interface.
