Class Summary

Class	Description
Ast	A class representation of the parser-generated Abstract Syntax Tree (AST).
Ast.AstCallback	The base class for all AST callback functions.
Generator	The Generator class has a static main() function which is APG, the ABNF Parser Generator.
GeneratorGrammar	This class has been generated automatically from an SABNF grammar by the Generator class of Java APG, Version 1.1.0. It is an extension of the Grammar class containing additional members and enums not found in the base class. The function GeneratorGrammar.getInstance() will return a reference to a static, singleton instance of the class.
Grammar	The Grammar class is the interface between the Parser Generator and the Parser.
Parser	The Parser class is used to construct a parser for a specific grammar.
Parser.RuleCallback	The base class for all rule callback functions.
Parser.UdtCallback	Base class for all User-Defined Terminals (UDTs).
Statistics	The Statistics class is used to collect and display syntax tree node statistics.
Trace	The Trace class will display the exact path followed by the parser on its journey through the syntax tree.
UdtLib	This is the parent class for a library of User-Defined Terminals (UDTs).
UdtLib.Alphanum	UDT for recognizing alpha-numeric phrases.
UdtLib.Any	UDT for recognizing a string of any printing characters.
UdtLib.CComment	UDT for recognizing the C-language comments.
UdtLib.Comment	UDT for many common comment formats.
UdtLib.CppComment	UDT for the C++ language comment.
UdtLib.CRLFLineEnd	UDT for the standard CRLF line end. CR = carriage return, \r or x0D LF = line feed, newline, \n or x0A
UdtLib.DecNum	UDT for a decimal number.
UdtLib.DoubleQuotedString	UDT for the double-quoted string.
UdtLib.ForgivingLineEnd	UDT for a "forgiving" line end.
UdtLib.HexNum	UDT for a hexidecimal number.
UdtLib.LFLineEnd	UDT for the LF or newline line end. LF = line feed, newline, \n or x0A
UdtLib.LineEnd	UDT for line end characters.
UdtLib.QuotedString	UDT for the quoted-string.
UdtLib.SemiComment	UDT for the ABNF comment.
UdtLib.SingleQuotedString	UDT for the single-quoted string.
UdtLib.WhiteSpace	UDT for any of several choices for white space characters.
Utilities	The Utilities class defines several helper classes and static functions.
Utilities.LineCatalog	A class for reading a text file and cataloging its text lines.
Utilities.XMLWriter	A class for assisting in the writing of XML files.

Enum Summary

Enum	Description
GeneratorGrammar.RuleNames	This enum provides easy to remember enum constants for locating the rule identifiers and names.
GeneratorGrammar.UdtNames	This enum provides easy to remember enum constants for locating the UDT identifiers and names.
