Uses of StateCluster in org.antlr.tool
 

Methods in org.antlr.tool that return StateCluster
 StateCluster NFAFactory.build_AB(StateCluster A, StateCluster B)
          From A B build A-e->B (that is, build an epsilon arc from right of A to left of B).
 StateCluster NFAFactory.build_Action(GrammarAST action)
          Build what amounts to an epsilon transition with an action.
 StateCluster NFAFactory.build_AlternativeBlock(java.util.List alternativeStateClusters)
          From A|B|..|Z alternative block build o->o-A->o->o (last NFAState is blockEndNFAState pointed to by all alts) | ^ o->o-B->o--| | | ...
 StateCluster NFAFactory.build_AlternativeBlockFromSet(StateCluster set)
          From a set ('a'|'b') build o->o-'a'..'b'->o->o (last NFAState is blockEndNFAState pointed to by all alts)
 StateCluster NFAFactory.build_Aoptional(StateCluster A)
          From (A)? build either: o--A->o | ^ o---->| or, if A is a block, just add an empty alt to the end of the block
 StateCluster NFAFactory.build_Aplus(StateCluster A)
          From (A)+ build |---| (Transition 2 from A.right points at alt 1) v | (follow of loop is Transition 1) o->o-A-o->o Meaning that the last NFAState in A points back to A's left Transition NFAState and we add a new begin/end NFAState.
 StateCluster NFAFactory.build_Astar(StateCluster A)
          From (A)* build |---| v | o->o-A-o--o (Transition 2 from block end points at alt 1; follow is Transition 1) | ^ o---------| (optional branch is 2nd alt of optional block containing A+) Meaning that the last (end) NFAState in A points back to A's left side NFAState and we add 3 new NFAStates (the optional branch is built just like an optional subrule).
 StateCluster NFAFactory.build_Atom(GrammarAST atomAST)
           
 StateCluster NFAFactory.build_Atom(int label, GrammarAST associatedAST)
          From label A build Graph o-A->o
 StateCluster NFAFactory.build_CharLiteralAtom(GrammarAST charLiteralAST)
          From char 'c' build StateCluster o-intValue(c)->o
 StateCluster NFAFactory.build_CharRange(java.lang.String a, java.lang.String b)
          From char 'c' build StateCluster o-intValue(c)->o can include unicode spec likes '$' later.
 StateCluster NFAFactory.build_Epsilon()
          From an empty alternative build StateCluster o-e->o
 StateCluster NFAFactory.build_Range(int a, int b)
          Can only complement block of simple alts; can complement build_Set() result, that is.
 StateCluster NFAFactory.build_RuleRef(Rule refDef, NFAState ruleStart)
          For reference to rule r, build o-e->(r) o where (r) is the start of rule r and the trailing o is not linked to from rule ref state directly (it's done thru the transition(0) RuleClosureTransition.
 StateCluster NFAFactory.build_SemanticPredicate(GrammarAST pred)
          Build what amounts to an epsilon transition with a semantic predicate action.
 StateCluster NFAFactory.build_Set(IntSet set, GrammarAST associatedAST)
          From set build single edge graph o->o-set->o.
 StateCluster NFAFactory.build_StringLiteralAtom(GrammarAST stringLiteralAST)
          For a non-lexer, just build a simple token reference atom.
 StateCluster NFAFactory.build_Wildcard(GrammarAST associatedAST)
          Build an atom with all possible values in its label
 StateCluster NFAFactory.build_WildcardTree(GrammarAST associatedAST)
          Build a subrule matching ^(.

 void NFAFactory.optimizeAlternative(StateCluster alt)
          Optimize an alternative (list of grammar elements).
