    • isKnowDeadCodePattern

      protected static boolean isKnowDeadCodePattern(Expression expression)
      Answers true if the if is identified as a known coding pattern which should be tolerated by dead code analysis. e.g. if (DEBUG) print(); // no complaint Only invoked when overall condition is known to be optimizeable into false/true.

    • analyseCode

      public abstract FlowInfo analyseCode(BlockScope currentScope, FlowContext flowContext, FlowInfo flowInfo)

    • doesNotCompleteNormally

      public boolean doesNotCompleteNormally()
      Lambda shape analysis: *Assuming* this is reachable, analyze if this completes normally i.e control flow can reach the textually next statement. For blocks, we don't perform intra-reachability analysis. We assume the lambda body is free of intrinsic control flow errors (if such errors exist they will not be flagged by this analysis, but are guaranteed to surface later on.)

    • completesByContinue

      public boolean completesByContinue()
      Lambda shape analysis: *Assuming* this is reachable, analyze if this completes by continuing i.e control flow cannot reach the textually next statement. This is necessitated by the fact that continue claims to not complete normally. So this is necessary to discriminate between do { continue; } while (false); which completes normally and do { throw new Exception(); } while (false); which does not complete normally.

    • canCompleteNormally

      public boolean canCompleteNormally()
      Switch Expression analysis: *Assuming* this is reachable, analyze if this completes normally i.e control flow can reach the textually next statement, as per JLS 14 Sec 14.22 For blocks, we don't perform intra-reachability analysis. Note: delinking this from a similar (opposite) doesNotCompleteNormally() since that was coded for a specific purpose of Lambda Shape Analysis.
