Interface Summary

Atom	There are different kinds of atoms: text, boolean, number.
SEListVisitor<Ret>	The usual generically typed visitor for functional lists.
SExp	SExp ::= Atom | SEList SEList ::= Empty | Cons(SExp, SEList) Atom ::= text | number | boolean text ::= string | symbol string ::= "non-quote-char*" symbol ::= non-special-char* non-quote-char ::= alphanumeric | escapes | white-sp-char | other escapes ::= \" | \\ white-sp-char ::= ascii chars from 0-32 boolean ::= true | false number ::= digit* {.
SExpVisitor<Ret>	Just your every-day visitor.
Tokens	A common namespace for the token classes.

NumberAtom
QuotedTextAtom	this type of text atom is mostly like its super class except its string representation includes the sourrounding quotes and the instances of the characters: \ " etc are turned into their corresponding escape character sequences.
SEList
SExpParser	This parser is not meant to be instantiated.
SExpParser.ParseHelper	A new helper is instantiated for each time the user wants to parse data.
SExpParserTest	A JUnit test case class.
TextAtom
Tokens.BackSlashToken
Tokens.BooleanToken	Words include any text (including symbols) that is not a number, a backslash, or a quote character.
Tokens.LeftParenToken
Tokens.NumberToken	Numbers are string s of only digits (0-9)
Tokens.QuotedTextToken	This token is handled as a unit by the lexer.
Tokens.RightParenToken
Tokens.SExpToken	These tokens are designed to be compared using the == operator with (, ), ", and \.
Tokens.WordToken	Words include any text (including symbols) that is not a number, a backslash, or a quote character.
TokensTest	Test class for Tokens.java in this package.

Exception Summary

LexingException	This exception is used by the lexer.
SExpParseException
SExpParser.PrivateParseException	This runtime exception makes it easier to write the parser since the methods of the helper class won't need to constantly declare the SExpParseException to be thrown.
