public class JavaCCGlobals extends java.lang.Object
This package contains data created as a result of parsing and semanticizing a JavaCC input file. This data is what is used by the back-ends of JavaCC as well as any other back-end of JavaCC related tools such as JJTree.

public static java.lang.String cu_name
The name of the parser class (what appears in PARSER_BEGIN and PARSER_END).
-
cu_to_insertion_point_1
public static java.util.List<Token> cu_to_insertion_point_1
This is a list of tokens that appear after "PARSER_BEGIN(name)" all the way until (but not including) the opening brace "{" of the class "name".
-
cu_to_insertion_point_2
public static java.util.List<Token> cu_to_insertion_point_2
This is the list of all tokens that appear after the tokens in "cu_to_insertion_point_1" and until (but not including) the closing brace "}" of the class "name".
-
cu_from_insertion_point_2
public static java.util.List<Token> cu_from_insertion_point_2
This is the list of all tokens that appear after the tokens in "cu_to_insertion_point_2" and until "PARSER_END(name)".
-
bnfproductions
public static java.util.List<NormalProduction> bnfproductions
A list of all grammar productions - normal and JAVACODE - in the order they appear in the input file. Each entry here will be a subclass of "NormalProduction".
-
production_table
public static java.util.Map production_table
A symbol table of all grammar productions - normal and JAVACODE. The symbol table is indexed by the name of the left hand side non-terminal. Its contents are of type "NormalProduction".
-
lexstate_S2I
public static java.util.Hashtable<java.lang.String,java.lang.Integer> lexstate_S2I
A mapping of lexical state strings to their integer internal representation. Integers are stored as java.lang.Integer's.
-
lexstate_I2S
public static java.util.Hashtable<java.lang.Integer,java.lang.String> lexstate_I2S
A mapping of the internal integer representations of lexical states to their strings. Integers are stored as java.lang.Integer's.
-
token_mgr_decls
public static java.util.List token_mgr_decls
The declarations to be inserted into the TokenManager class.
-
rexprlist
public static java.util.List<TokenProduction> rexprlist
The list of all TokenProductions from the input file. This list includes implicit TokenProductions that are created for uses of regular expressions within BNF productions.
-
tokenCount
public static int tokenCount
The total number of distinct tokens. This is therefore one more than the largest assigned token ordinal.
-
named_tokens_table
public static java.util.Map named_tokens_table
This is a symbol table that contains all named tokens (those that are defined with a label). The index to the table is the image of the label and the contents of the table are of type "RegularExpression".
-
ordered_named_tokens
public static java.util.List<RegularExpression> ordered_named_tokens
Contains the same entries as "named_tokens_table", but this is an ordered list which is ordered by the order of appearance in the input file.
-
names_of_tokens
public static java.util.Map<java.lang.Integer,java.lang.String> names_of_tokens
A mapping of ordinal values (represented as objects of type "Integer") to the corresponding labels (of type "String"). An entry exists for an ordinal value only if there is a labeled token corresponding to this entry. If there are multiple labels representing the same ordinal value, then only one label is stored.
-

public static java.util.Hashtable simple_tokens_table
This is a three-level symbol table that contains all simple tokens (those that are defined using a single string (with or without a label). The index to the first level table is a lexical state which maps to a second level hashtable. The index to the second level hashtable is the string of the simple token converted to upper case, and this maps to a third level hashtable. This third level hashtable contains the actual string of the simple token and maps it to its RegularExpression.
