public interface AdaptiveFeatureGenerator
Most implementors do not need the adaptive functionality of this
interface, they should extend the
FeatureGeneratorAdapter class instead.
Feature generation is not thread safe and a instance of a feature generator must only be called from one thread. The resources used by a feature generator are typically shared between man instances of features generators which are called from many threads and have to be thread safe. If that is not possible the
FeatureGeneratorFactory must make a copy
of the resource object for each feature generator instance.
