- // The CKeyValueList is a strange class, because it has some backward
- // compatibilities w/the old-style IHXValues. It supports these interfaces:
- //
- // IHXKeyValueList - non-uniquely list of strings
- // IHXValues - uniquely keyed lists of strings, buffers, ulongs
- //
- // FAQ:
- // ====
- //
- // Q: How can CKeyValueList support a non-uniquely keyed list of strings, while
- // also supporting a uniquely keyed list of strings?
- //
- // A: The class as a whole does not enforces uniqueness. If you exclusively use
- // GetPropertyCString/SetPropertyCString for any given key, though, you can be
- // sure that only one instance of that key exists. Read on.
- //
- // OVERVIEW OF CLASS INTERFACE:
- // ============================
- //
- // Basically, this class allows you to store three types of data:
- //
- // strings
- // buffers
- // ULONGs
- //
- // The data types are stored in completely separate data structures.
- //
- // Buffers and ULONGS are always uniquely keyed. Use these functions to
- // get/set Buffer/ULONG values:
- //
- // SetPropertyULONG32/GetPropertyULONG32
- // SetPropertyBuffer/GetPropertyBuffer
- //
- // Strings can be non-uniquely keyed. If you add a string using AddKeyValue,
- // you're gonna create a new key/string tuple, even if that key had already been
- // used for a string.
- //
- // AddKeyValue - add new tuple, even if key was already used
- // GetIterOneKey - see "Iterating"
- //
- // GetPropertyCString - fail if no strings for that key; otherwise, return
- // first string inserted for that key
- // SetPropertyCString - write new tuple if no strings for that key; otherwise,
- // change first tuple for that key to use new string
- //
- // Mixing and matching AddKeyValue calls w/SetPropertyCString calls is allowable,
- // but generally indicates a muddled understanding of the interfaces.
- //
- // Iterating --
- // -------------
- // To iterate over all your ULONG keys, use these functions:
- //
- // GetFirstPropertyULONG32/GetNextPropertyULONG32
- //
- // To iterate over all your buffer keys, use these functions:
- //
- // GetFirstPropertyBuffer/GetNextPropertyBuffer
- //
- // To iterate over all your strings, use these functions:
- //
- // GetIter ... while (GetNextPair == HXR_OK)
- //
- // These are preferred to GetFirstPropertyCString/GetNextPropertyCString,
- // because they are reentrant. You can use the old interface, though.
- //
- // To iterate all the strings for a key, use these functions:
- //
- // GetIterOneKey ... while (GetNextString == HXR_OK)
- //
- // While iterating, you can replace the current string by calling ReplaceCurr.
- // This is particulary useful when you are replacing several strings for the
- // same key, like for mangling all cookies.
- //
- //
- // SOME HISTORY:
- // =============
- // The predecessor to this class was CKeyedIList, and various cousins that were
- // never really used. The classes were replaced, due to strange interfaces and
- // abusive precompiler usage.
- //
- //
- // USAGE/PERFORMANCE CONSIDERATIONS:
- // =================================
- // Don't use this class if you know all your keys are always going to be unique.
- // You'd be better off using CHXHeader for that, or some other class that
- // supports only IHXValues. On the other hand, even w/the extra baggage of
- // IHXKeyValueList, this class is simpler than most other IHXValue variants,
- // so it might be good to use if you don't have a lot of keys. This class uses
- // linked lists, and linear seaches. Most other classes use hashes.
- //
- // This class should have the exact behavior as CHXHeaders for buffers and ULONGs.
- // Most users of this class barely do anything w/buffers and ULONGs. If, however,
- // this class ever becomes a performance bottleneck, a good thing to do may be to
- // steal the CHXHeader code that relates to buffers and ulongs. You're probably
- // best off cutting-and-pasting CHXHeader code, or in a pinch, you can have this
- // class wrap an actual CHXHeader object, and the string methods just get ignored.
- // Another option is to add a hash table to this implementation to speed up lookups.
