  com.antelmann.math.DefaultDataParser<T>

All Implemented Interfaces:

DataParser<T>

public class DefaultDataParser<T>
extends Object
implements DataParser<T>

a default implementation of a DataParser based on PatternExtractor instances. As a parser should provide stable results, the instance cannot be altered while in use.
