  • Method Details

    • getTypeMirror

      @NonNull JTypeMirror getTypeMirror()
      Returns the type of the functional interface. E.g. in stringStream.map(s -> s.isEmpty()), this is java.util.function.Function<java.lang.String, java.lang.Boolean>.
      Specified by:
      getTypeMirror in interface TypeNode
      Returns:
      The type mirror. Never returns null; if the type is unresolved, returns TypeSystem.UNKNOWN.
