<p class="commentary firstcommentary"><a id="SP1" class="paragraph-anchor"></a><b>§1. Block Format. </b>Inform uses a rich variety of relations, with many different data representations,
|
|
but we aim to hide that complexity from the user. At run-time, a relation is
|
|
represented by a block value. The short block of this BV is simply a pointer
|
|
to a long block. This always begins with at least six words of metadata, but
|
|
actual data sometimes follows on, and sometimes doesn't: and its format is
|
|
something the customer needn't know about.
|
|
</p>
|
|
|
|
<p class="commentary">The low-level routines in "Relations.i6t" access this metadata by direct use
|
|
of <span class="extract"><span class="extract-syntax">--></span></span>, for speed, and they use the offset constants <span class="extract"><span class="extract-syntax">RR_NAME</span></span> and so on;
|
|
but we will use the <span class="extract"><span class="extract-syntax">BlkValueRead</span></span> and <span class="extract"><span class="extract-syntax">BlkValueWrite</span></span> routines in this
|
|
section, which need offsets in the form <span class="extract"><span class="extract-syntax">RRV_NAME</span></span>. (The discrepancy of 5 is
|
|
to allow for the five-word block header.)

creating, a relation. For example, if we write

</p>

|
<blockquote>
|
|
<p>let Q be a relation of objects to objects;</p>
|

<p class="commentary">...we aren't literally asking for Q to be a duplicate copy of containment,

pointer to the one and only containment relation. On the other hand, if we

write

<p class="commentary">We cope with this at creation time. If we're invited to create a copy of an

existing relation, we look to see if it is empty — which we detect by its
|
|
use of the <span class="extract"><span class="extract-syntax">EmptyRelationHandler</span></span> handler. The empty relations are exactly
|
|
those used as default values for the relation kinds; thus that's what will
|
|
happen when Q is created. If we find this handler, we intercept and replace
|
|
it with one of the heap relation handlers, which thus makes the relation a
|
|
newly constructed data structure which can grow freely from here.

<p class="commentary firstcommentary"><a id="SP15" class="paragraph-anchor"></a><b>§15. Double Hash Set Relation Handler. </b>This implements relations which are stored as a double-hashed set.
|
|
The storage comprises a list of three-word entries \((F, X, Y)\), where
|
|
\(F\) is a flags word. The ordering of the list is determined by a probe
|
|
sequence which depends on the combined hash values of \(X\) and \(Y\).
|
|
</p>
|
|
|
|
<p class="commentary">The "storage" word in the header stores one less than the number of
|
|
entries in the list; the number of entries in the list is always a
|
|
power of two, so this will always be a bit mask. The "used" and
|
|
"filled" words store the number of entries which currently hold a
|
|
value, and the number of entries which have ever held a value (even
|
|
if it was since deleted), respectively.
|
|
</p>
|
|
|
|
<p class="commentary">The utility routine <span class="extract"><span class="extract-syntax">DoubleHashSetLookUp</span></span> locates the hash entry for
|
|
a key/value pair. It returns either the (non-negative) number of the
|
|
entry where the pair was found, or the (negative) bitwise NOT of the
|
|
number of the first unused entry where the pair could be inserted. It
|
|
uses the utility routine <span class="extract"><span class="extract-syntax">DoubleHashSetEntryMatches</span></span> to compare
|
|

<p class="commentary firstcommentary"><a id="SP21" class="paragraph-anchor"></a><b>§21. Equivalence Hash Table Relation Handler. </b>This implements group relations. The table format is identical to that used
|
|
by <span class="extract"><span class="extract-syntax">HashCoreRelationHandler</span></span>, but we use it differently. Although the
|
|
relation appears to relate Xs to Xs as far as the game is concerned, the
|
|
table actually relates Xs to numbers, where each number identifies a
|
|
group of related items. Any X not listed in the table is implicitly in
|
|
a single-member group.
|
|
</p>
|
|
|
|
<p class="commentary">When a pair \((X, Y)\) is inserted, one of four cases occurs:
|
|
</p>
|
|
|
|
<p class="commentary">1. Neither \(X\) nor \(Y\) has a table entry. We search the table to find the
|
|
next unused group number, then add both \(X\) and \(Y\) to that group.
|
|
</p>
|
|
|
|
<p class="commentary">2. Both \(X\) and \(Y\) have existing table entries. If the group numbers
|
|
differ, we walk through the table and change all occurrences of the
|
|
higher number to the lower one.
|
|
</p>
|
|
|
|
<p class="commentary">3. \(X\) has an existing table entry but \(Y\) does not. We add a \(Y\) entry
|
|
using the group number of \(X\).
|
|
</p>
|
|
|
|
<p class="commentary">4. \(Y\) has an existing table entry but \(X\) does not. We add an \(X\) entry
|
|
using the group number of \(Y\).
|
|
</p>
|
|
|
|
<p class="commentary">When a pair \((X, Y)\) is removed, we first verify that \(X\) and \(Y\) are
|
|
in the same group, then delete the table entry for \(X\). This may leave
|
|
\(Y\) in a single-member group, which could be deleted, but detecting that
|
|
situation would be inefficient, so we keep the \(Y\) entry regardless.

<p class="commentary firstcommentary"><a id="SP22" class="paragraph-anchor"></a><b>§22. Two-In-One Hash Table Relation Handler. </b>This implements one-to-one relations, which are stored as a hash table
|
|
mapping keys to single values and vice versa. To enforce the one-to-one
|
|
constraint, we need the ability to quickly check whether a value is
|
|
present. This could be done with two separate hash tables, one mapping X to Y
|
|
and one the opposite, but in the interest of conserving memory, we use a
|
|
single table for both.
|
|
</p>
|
|
|
|
<p class="commentary">Each four-word entry \((F, E, K, V)\) consists of a flags word \(F\), an entry
|
|
key \(E\) (which may be a "key" or "value" in the hash table sense), a
|
|
corresponding key \(K\) (when \(E\) is used as a value), and a corresponding
|
|
value \(V\) (when \(E\) is used as a key). The pair of related values \((X, Y)\)
|
|
is represented as two table entries: \((F, X, _, Y)\) and \((F, Y, X, _)\).
|
|
</p>
|
|
|
|
<p class="commentary">To conserve memory when block values are used, we only create one copy
|
|
of \(X\) and/or \(Y\) to share between both entries. When adding a key or value
|
|
which already exists on either side of the relation, the previous copy will
|
|
be used. Copies are freed when they are no longer used as entry keys.
|
|
</p>
|
|
|
|
<p class="commentary">Each entry's flags word \(F\) indicates, in addition to the standard flags
|
|
<span class="extract"><span class="extract-syntax">RRF_USED</span></span> and <span class="extract"><span class="extract-syntax">RRF_DELETED</span></span>, also whether the entry contains a
|
|
corresponding key \(K\) and/or value \(V\) (<span class="extract"><span class="extract-syntax">RRF_HASX</span></span>, <span class="extract"><span class="extract-syntax">RRF_HASY</span></span>) and
|
|
whether the entry's key is the same kind of value as \(X\) or \(Y\)
|
|
(<span class="extract"><span class="extract-syntax">RRF_ENTKEYX</span></span>, <span class="extract"><span class="extract-syntax">RRF_ENTKEYY</span></span>). If both sides of the relation use the
|
|
same kind of value, or if both sides are word values, both <span class="extract"><span class="extract-syntax">RRF_ENTKEYX</span></span>
|
|
and <span class="extract"><span class="extract-syntax">RRF_ENTKEYY</span></span> will be set on every used entry.
|
|
</p>
|
|
|
|
<p class="commentary">Of particular note for this handler is the utility function <span class="extract"><span class="extract-syntax">TwoInOneDelete</span></span>,
|
|
which clears one half of an entry (given its entry key), and optionally
|
|
clears the corresponding other half stored in a different entry. That is,
|
|
given the entries \((F, X, _, Y)\) at index <span class="extract"><span class="extract-syntax">i</span></span> and \((F, Y, X, _)\) elsewhere,
|
|
<span class="extract"><span class="extract-syntax">TwoInOneDelete(rel, i, kx, ky, RRF_ENTKEYX, 1)</span></span> will clear both entries
|
|
and mark them as deleted. If, however, those entries overlap with other
|
|
pairs — say they're \((F, X, A, Y)\) and \((F, Y, X, B)\) — then the same call
|
|
to <span class="extract"><span class="extract-syntax">TwoInOneDelete</span></span> will leave us with \((F, X, A, _)\) and \((F, Y, _, B)\),
|
|
having cleared the parts corresponding to the pair \((X, Y)\) but not the
|
|
parts corresponding to the pairs \((A, X)\) and \((Y, B)\), and will not mark
|
|
either as deleted. (Such overlap is only possible when the domains of \(X\)
|
|
and \(Y\) are the same kind of value.)

<p class="commentary firstcommentary"><a id="SP23" class="paragraph-anchor"></a><b>§23. Empty. </b>This implements the "empty" adjective. We can always check whether a relation
|
|
is empty. For most relation types, we can cause the relation to become empty by
|
|
removing all pairs: but this is impossible for equivalence relations, which are
|
|
never empty, since any \(X\) is equivalent to itself. And we can never force a
|
|
relation to become non-empty, since that would require making up data.
|
|
</p>
|
|
|
|
<p class="commentary">In any case, the implementation is delegated to the relation handler.
