public interface PreconstructedFilter
extends Preconstructed
Marker interface for a filter that has been Preconstructed. Users of such a
filter can assume that it is Streamable and that input() can be called
immediately in order to process new instances; furthermore, such a filter
should make an output instance available immediately after input() is called.
Implementers of a PreconstructedFilter should perform any initialization and
processing necessary when setInputFormat() is called. They should not assume
or rely on there being anything but a header supplied to setInputFormat().
Once setInputFormat() has been called, the filter is deemed to be
"preconstructed".
