  - ### isInvariant

    public boolean isInvariant()
    Description copied from interface: `Asset`
    Returns true if the Asset is invariant (meaning that it returns the same value from `Asset.toClientURL()` at all times). Most Assets are invariant. Assets that are used as binding values will be cached more aggressively by Tapestry if they are invariant. This default implementation returns `false`
    Specified by:
      `isInvariant` in interface `Asset`
    Returns:
      true if invariant

  - ### toString

    public String toString()
    Returns `Asset.toClientURL()`.

      `toString` in class `Object`
