## org.biojava.bio.seq.io
Class WordTokenization

    java.lang.Object
      org.biojava.utils.Unchangeable
          org.biojava.bio.seq.io.WordTokenization

All Implemented Interfaces:
  Serializable, Annotatable, SymbolTokenization, Changeable

Direct Known Subclasses:
  CrossProductTokenization, DoubleTokenization, IntegerTokenization, NameTokenization, SubIntegerTokenization

    public abstract class WordTokenization

extends Unchangeable
implements SymbolTokenization, Serializable

Base class for tokenizations which accept whitespace-separated `words'. Splits at whitespace, except when it is quoted by either double-quotes ("), brackets (), or square brackets [].
