28 :
29 : Objects of this type are used to interpret
30 : the query parameters as a bidirectional view
31 : of key value pairs.
32 :
33 : The view does not retain ownership of the
34 : elements and instead references the original
35 : url. The caller is responsible for ensuring
36 : that the lifetime of the referenced url
37 : extends until it is no longer referenced.
38 :
39 : The view is modifiable; calling non-const
40 : members causes changes to the referenced
41 : url.
42 :
43 : @par Example
44 : @code
45 : url u( "?first=John&last=Doe" );
46 :
47 : params_encoded_ref p = u.encoded_params();
48 : @endcode
49 :
50 : Strings produced when elements are returned
51 : have type @ref param_pct_view and represent
52 : encoded strings. Strings passed to member
53 : functions may contain percent escapes, and
54 : throw exceptions on invalid inputs.
55 :
56 : @par Iterator Invalidation
57 : Changes to the underlying character buffer
58 : can invalidate iterators which reference it.
59 : Modifications made through the container
60 : invalidate some iterators to the underlying
61 : character buffer:
62 : @li @ref append : Only `end()`.
63 : @li @ref assign, @ref clear,
64 : `operator=` : All params.
65 : @li @ref erase : Erased params and all
66 : params after (including `end()`).
67 : @li @ref insert : All params at or after
68 : the insertion point (including `end()`).
69 : @li @ref replace, @ref set : Modified
70 : params and all params
71 : after (including `end()`).
