      • setGeneration

        public void setGeneration​(long generation)
        Description copied from class: Generator
        Sets the current generation count. This should be eventually noticeable for callers of Generator.getGeneration(). An odd number means the library is enabled, while an even number means the library is disabled.
        Overrides:
        setGeneration in class Generator
        Parameters:
        generation - the generation id, shifted left by Generator.GEN_OFFSET.

      • getGeneration

        public long getGeneration()
        Description copied from class: Generator
        Gets the current generation, shifted left by Generator.GEN_OFFSET. An odd number means the library is enabled, while an even number means the library is disabled.
        Overrides:
        getGeneration in class Generator
        Returns:
        the current generation or Generator.FAILURE.

      • costOfGetNanos

        public long costOfGetNanos()
        Description copied from class: Generator
        Returns the approximate cost to read the generation.
        Overrides:
        costOfGetNanos in class Generator
        Returns:
        an approximate number of nanoseconds needed to read the generator value.

      • costOfSetNanos

        public long costOfSetNanos()
        Description copied from class: Generator
        Returns the approximate cost to change the generation.
        Overrides:
        costOfSetNanos in class Generator
        Returns:
        an approximate number of nanoseconds needed to change the generator value.
