It has accessors for all the cache-control directives specified in RFC 2616. The class does not differentiate between request and response directives. Because the cache-control directives in the HTTP header use dashes the python descriptors use underscores for that. To get a header of the :class:`CacheControl` object again you can convert the object into a string or call the :meth:`to_header` method. If you plan to subclass it and add your own items have a look at the sourcecode for that class. .. versionchanged:: 3.1 Dict values are always ``str | None``. Setting properties will convert the value to a string. Setting a non-bool property to ``False`` is equivalent to setting it to ``None``. Getting typed properties will return ``None`` if conversion raises ``ValueError``, rather than the string. .. versionchanged:: 2.1 Setting int properties such as ``max_age`` will convert the value to an int. .. versionchanged:: 0.4 Setting ``no_cache`` or ``private`` to ``True`` will set the implicit value ``"*"``. zno-storeNrno_storezmax-age int | Nonemax_agez no-transform no_transformzstale-if-errorstale_if_errorrvaluesBcabc.Mapping[str, t.Any] | cabc.Iterable[tuple[str, t.Any]] | None on_update+cabc.Callable[[_CacheControl], None] | Nonecst|||du|_dSr)super__init__provided)selfr+r- __class__rrr0Zsz_CacheControl.__init__r r r r r rrcCs`|tur||vS||vrdS||}dur|S|dur.z||}W|Sty-YdSw|S+Used internally by the accessor properties.N)r ValueError)r2r r r valuerrrrbs  z_CacheControl._get_cache_valuer8NonecCs||tur|r d||<dS||ddS|dus|dur$||ddS|dur.d||<dS|dur6||}t|||<dS)r6NFT)rpopr )r2r r8r rrrrws  z_CacheControl._set_cache_valuecCs||vr ||=dSdSr5r)r2r rrrrs z_CacheControl._del_cache_valuecCs t|S)z6Convert the stored values into a cache control header.)http dump_headerr2rrr to_headers z_CacheControl.to_headercCs|Sr)r>r=rrr__str__sz_CacheControl.__str__cCs4dddt|D}dt|jd|dS)Nrcss"|] \}}|d|VqdS)=Nr).0krrrr s z)_CacheControl.__repr__..<>)r!sorteditemsr r )r2kv_strrrr__repr__sz_CacheControl.__repr__)rN)r+r,r-r.)r r r r r rrr )r r r8r r rrr9)r r rr9)rr )r __module__ __qualname____doc__r$rr&__annotations__intr(r)r*r0rrrr>r?rI staticmethodcache_property __classcell__rrr3rr%8s       r%c@sbeZdZUdZeddeZded<eddeZ ded <ed deZ d ed <ed deZ ded<dS)RequestCacheControla A cache control for requests.
