Package org.antlr.tool

Interface Summary

Interface	Description
ANTLRErrorListener	Defines behavior of object able to handle error messages from ANTLR including both tool errors like "can't write file" and grammar ambiguity warnings.

Class Summary

Class	Description
AssignTokenTypesBehavior	Move all of the functionality from assign.types.g grammar file.
Attribute	Track the names of attributes define in arg lists, return values, scope blocks etc...
AttributeScope	Track the attributes within a scope.
BuildDependencyGenerator	Given a grammar file, show the dependencies on .tokens etc...
CompositeGrammar	A tree of component (delegate) grammars.
CompositeGrammarTree	A tree of grammars
DOTGenerator	The DOT (part of graphviz) generation aspect.
ErrorManager	Defines all the errors ANTLR can generator for both the tool and for issues with a grammar.
ErrorManager.ErrorState
FASerializer	An aspect of FA (finite automata) that knows how to dump them to serialized strings.
Grammar	Represents a grammar in memory.
Grammar.Decision
GrammarAnalysisAbortedMessage	Reports the condition that ANTLR's LL(*) analysis engine terminated early.
GrammarAST	Grammars are first converted to ASTs using this class and then are converted to NFAs via a tree walker.
GrammarDanglingStateMessage	Reports a potential parsing issue with a decision; the decision is nondeterministic in some way.
GrammarInsufficientPredicatesMessage
GrammarNonDeterminismMessage	Reports a potential parsing issue with a decision; the decision is nondeterministic in some way.
GrammarReport
GrammarReport.ReportData
GrammarReport2	Simplifying report dramatically for LL(*) paper.
GrammarSanity	Factor out routines that check sanity of rules, alts, grammars, etc..
GrammarSemanticsMessage	A problem with the symbols and/or meaning of a grammar such as rule redefinition.
GrammarSerializerFoo	Serialize a grammar into a highly compressed form with only the info needed to recognize sentences.
GrammarSpelunker	Load a grammar file and scan it just until we learn a few items of interest.
GrammarSpelunker.Scanner	Strip comments and then return stream of words and tokens {';', ':', '{', '}'}
GrammarSyntaxMessage	A problem with the syntax of your antlr grammar such as "The '{' came as a complete surprise to me at this point in your program"
GrammarUnreachableAltsMessage	Reports a potential parsing issue with a decision; the decision is nondeterministic in some way.
Interp	Interpret any ANTLR grammar: java Interp file.g tokens-to-ignore start-rule input-file java Interp C.g 'WS COMMENT' program t.c where the WS and COMMENT are the names of tokens you want to have the parser ignore.
Interp.FilteringTokenStream
Interpreter	The recognition interpreter/engine for grammars.
LeftRecursionCyclesMessage	Similar to LeftRecursionMessage except this is used for announcing cycles found by walking rules without decisions; the other msg is invoked when a decision DFA construction finds a problem in closure.
LeftRecursiveRuleAnalyzer
Message	The ANTLR code calls methods on ErrorManager to report errors etc...
NameSpaceChecker
NFAFactory	Routines to construct StateClusters from EBNF grammar constructs.
NonRegularDecisionMessage	More a single alternative recurses so this decision is not regular.
RandomPhrase	Generate a random phrase given a grammar.
RecursionOverflowMessage	Indicates recursion overflow.
Rule	Combine the info associated with a rule.
RuleLabelScope
Strip	A basic action stripper.
ToolMessage	A generic message from the tool such as "file not found" type errors; there is no reason to create a special object for each error unlike the grammar errors, which may be rather complex.
ToolSTGroupFile	This extension of STGroupFile automatically sets the group's STErrorListener to ErrorManager.getSTErrorListener().
