    • phase2list

      private final List phase2list
      These lists are used to maintain expansions for which code generation in phase 2 and phase 3 is required. Whenever a call is generated to a phase 2 or phase 3 routine, a corresponding entry is added here if it has not already been added. The phase 3 routines have been optimized in version 0.7pre2. Essentially only those methods (and only those portions of these methods) are generated that are required. The lookahead amount is used to determine this. This change requires the use of a hash table because it is now possible for the same phase 3 routine to be requested multiple times with different lookaheads. The hash table provides a easily searchable capability to determine the previous requests. The phase 3 routines now are performed in a two step process - the first step gathers the requests (replacing requests with lower lookaheads with those requiring larger lookaheads). The second step then generates these methods. This optimization and the hashtable makes it look like we do not need the flag "phase3done" any more. But this has not been removed yet.

    • GenerateCodeProduction

      private void GenerateCodeProduction(org.javacc.parser.CodeProduction production, org.javacc.parser.CodeGeneratorSettings settings, org.javacc.utils.CodeBuilder codeGenerator)

    • processProductions

    • genFirstSet

      private void genFirstSet(org.javacc.parser.Expansion exp)
      Sets up the array "firstSet" above based on the Expansion argument passed to it. Since this is a recursive function, it assumes that "firstSet" has been reset before the first call.

    • dumpLookaheads

      private void dumpLookaheads(org.javacc.parser.Lookahead[] conds, String[] actions)

    • buildLookaheadChecker

      String buildLookaheadChecker(org.javacc.parser.Lookahead[] conds, String[] actions)
      This method takes two parameters - an array of Lookahead's "conds", and an array of String's "actions". "actions" contains exactly one element more than "conds". "actions" are Java source code, and "conds" translate to conditions - so lets say "f(conds[i])" is true if the lookahead required by "conds[i]" is indeed the case. This method returns a string corresponding to the Java code for: if (f(conds[0]) actions[0] else if (f(conds[1]) actions[1] . . . else actions[action.length-1] A particular action entry ("actions[i]") can be null, in which case, a noop is generated for that action.
