Class BaseSexp

java.lang.Object

  +--sexp.BaseSexp

Direct Known Subclasses:

Sexp, SList

public abstract class BaseSexp

extends Object

implements SExpression

This class is a base implementation of the SExpression interface. It mostly deals with converting the extending class to the various representations (canonical, transport and advanced). Unfortunately the exceptions thrown are RuntimeExceptions, not IOExceptions as they really should be. This both will and must change!
