   * Métodos públicos: pueden ser invocados por cualquiera, no se aplica ningún control de acceso. Los métodos son públicos por omisión excepto initiliaze que siempre es privado.
   * Métodos protegidos: sólo pueden ser invocados por objetos de la misma clase o subclases. El acceso se mantiene a la familia.
   * Métodos privados: no pueden ser invocados con un receptor explícito, el receptor siempre es self. Esto significa que los métodos privados sólo pueden ser llamados en el contexto del objeto actual, no se puede invocar los métodos privados de otro objeto.
