public class PeepholeCollectPropertyAssignments extends Object

    • report

      protected void report(DiagnosticType diagnostic, Node n)
      Helper method for reporting an error to the compiler when applying a peephole optimization.
      Parameters:
      diagnostic - The error type
      n - The node for which the error should be reported

    • reportCodeChange

      protected void reportCodeChange()
      Helper method for telling the compiler that something has changed. Subclasses must call these if they have changed the AST.

    • areNodesEqualForInlining

      protected boolean areNodesEqualForInlining(Node n1, Node n2)
      Are the nodes equal for the purpose of inlining? If type aware optimizations are on, type equality is checked.

    • isASTNormalized

      protected boolean isASTNormalized()
      Is the current AST normalized? (e.g. has the Normalize pass been run and has the Denormalize pass not yet been run?)
