- ## Method Details

  - ### get

    double get()
    Get the wrapped value. Unlike `WritableValue.getValue()`, this method returns primitive double. Needs to be identical to `WritableValue.getValue()`.
    Returns:
      The current value

  - ### set

    void set​(double value)
    Set the wrapped value. Unlike `setValue(java.lang.Number)`, this method uses primitive double.
    Parameters:
      `value` - The new value

  - ### setValue

    void setValue​(Number value)
    Set the wrapped value.

    Note: this method should accept null without throwing an exception, setting "0.0" instead.

    Specified by:
      `setValue` in interface `WritableValue<Number>`
    Parameters:
      `value` - The new value
