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.

Field Details
-
toolName
String that identifies the JavaCC generated files.- See Also:
-
fileName
The name of the grammar file being processed. -
origFileName
The name of the original file (before processing by JJTree). Currently this is the same as fileName. -
jjtreeGenerated
public static boolean jjtreeGeneratedSet to true if this file has been processed by JJTree. -
toolNames
The list of tools that have participated in generating the input grammar file. -
cu_name
The name of the parser class (what appears in PARSER_BEGIN and PARSER_END). -
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
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
This is the list of all tokens that appear after the tokens in "cu_to_insertion_point_2" and until "PARSER_END(name)". -
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
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
A mapping of lexical state strings to their integer internal representation. Integers are stored as java.lang.Integer's. -
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
The declarations to be inserted into the TokenManager class. -
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 tokenCountThe total number of distinct tokens. This is therefore one more than the largest assigned token ordinal. -
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
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
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. -
rexps_of_tokens
A mapping of ordinal values (represented as objects of type "Integer") to the corresponding RegularExpression_'s. -
simple_tokens_table
public static Map<String,Hashtable<String, simple_tokens_tableHashtable<String, RegularExpression_>>> 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_. -
maskindex
protected static int maskindexMask index shared between ParseEngine and ParseGen -
jj2index
protected static int jj2indexjj2 methods calls index shared between ParseEngine and ParseGen -
lookaheadNeeded
public static boolean lookaheadNeededTrue if lookahead needed, false otherwise -
maskVals
Mask values shared between ParseEngine and ParseGen -
cline
protected static int clineThe character's line -
ccol
protected static int ccolThe character's column
