Doug Cutting commented on LUCENE-1483:
--------------------------------------
Could we add a new class like
{code}
public abstract class Hitable {
public abstract void setBase(int base);
public abstract void hit(int doc, float score);
}
{code}
upgrade everything in trunk to use this, and change HitCollector to:
{code}
/** @deprecated */
public abstract class HitCollector extends Hitable {
public abstract void setBase() { throw new UOE(); }
}
{code}
then, for back-compatiblity, wrap anything that extends HitCollector to rebase?
Then you'd have neither an isSupported method nor use exceptions for control.
