Differences From Artifact [fdd2b6ed1c]:

  • File src/OFList.h — part of check-in [24ecf55297] at 2009-06-29 12:33:59 on branch trunk — Changes to OFDictionary, OFIterator and OFList - see details.

    OFDictionary:
    * More optimized way to internally store the data.
    * Faster resizing of dictionaries (no rehashing anymore).

    OFIterator:
    * Return a key/object pair rather than first the key and then the
    object.

    OFList:
    * Support for list objects with a different size so you can have your
    own list object structs. (user: js, size: 3309) [annotate] [blame] [check-ins using]
