/***********************************************************************
*
* ABCTBL1.C
*
* Contents Table
*
* The contents table associated with this provider. It's file based.
* The format of the .FAB file is in ABP.H.
*
* This implementation of IMAPITable is retrieved by calling the
* GetContentsTable() method of the Microsoft At Work Fax ABP's single
* directory (see abcont.c).
*
* There are a few interesting features in this implementation. First
* it's implemented on a flat file (.FAB). Second, it actually supports
* an implementation of ANR (Ambiguous Name Resolution). And lastly, it
* supports FindRow (limited to prefix searching on display names).
*
* This is the minimum set of restrictions that the provider MUST support.
* It MUST have an ANR implementation and support prefix (downward) searching
* on whatever the contents table is sorted on (in this case PR_DISPLAY_NAME).
*
* The browsing of a flat file is done a record at a time. It's never
* completely read into memory. It only reads records from the file when
* it absolutely has to (like in QueryRows). The advantage to this is
* a low memory footprint and the ability to browse rather large files
* with decent performance.
*/
/*
* ANR is also supported in this implementation. In the code will often
* be 'if' statements making two different code paths between the restricted
* and unrestricted version. The restrictions rely on a couple of
* bit arrays. Each bit corresponds (in order) to the records in the .FAB
* file. One bit array, rgChecked, says whether or not a record in the
* .FAB file has actually been compared to the restriction. It's initially
* set to all 0s - which means that none of the records have been checked.
* The second bit array, rgMatched, says whether or not the particular
* record matches the current restriction. This array is initialized to all
* 1s - which says that all the records in the .FAB file match the current
* restriction. The reason for this is for the fraction returned in
* QueryPosition--By assuming that all the rows match and only updating
* the array when something doesn't match, the fraction returned in
* QueryPosition will get larger and has the effect of making the thumb-bar
* on a listbox implemented on top of this table to scroll down as you go
* down the list.
*
* As a row is about to be read it is checked to see if it's been compared
* to the current restriction. If it has then to determine whether or not
* to actually read the record and build the row we just look at the matched
* bit array. If it doesn't match we go on to the next record and check
* again. If it does match we read the record and build the row.
*
* Only if it hasn't been checked do we actually go and read the row and
* compare it to the current restriction, setting the rgChecked and
* rgMatched bits accordingly.
*
* In this implementation the ANR comparison rules are as follows:
* (See FNameMatch for the actual code to do this)
*
* A 'word' is defined as any substring separated by separators.
* The separators are defined as ',', ' ', and '-'.
* A restriction is said to match a display name iff all the words
* in the restriction are all prefixes of words in the display name.
*
* For example, a restriction of "b d" will match:
* "Barney Donovan"
* "Donovan, Barney"
* "Danielle Blumenthal"
* But will not match:
* "Darby Opal"
* "Ben Masters"
*
* Other providers can do whatever matching they want with the ANR
* restriction. For example, soundex or additional field comparisons (like
* email addresses). A good (and fast) implementation will differentiate
* your provider from others in a positive way.
*
* FindRow's implementation effectively handles prefix searching on display
* names (PR_DISPLAY_NAME). It does this by binary searching the .FAB file.
* The only tricky part is knowing when to stop. Basically you want to stop
* on the first name in the list that matches the restriction. It's easy to
* do linearly, but a little more trick with a binary search. This
* implementation is a reasonable example.
*
*
* This table has only the following columns:
