<p>Association tables over ordered types.</p>
<p>This module implements applicative association tables, also known as
finite maps or dictionaries, given a total ordering function
over the keys.
All operations over maps are purely applicative (no side-effects).
The implementation uses balanced binary trees, and therefore searching
and insertion take time logarithmic in the size of the map.</p>
<p>For instance:</p>
<pre class="codepre"><code class="code"> <span class="keyword">module</span> <span class="constructor">IntPairs</span> =
<span class="keyword">struct</span>
<span class="keyword">type</span> t = int * int
<span class="keyword">let</span> compare (x0,y0) (x1,y1) =
<span class="keyword">match</span> <span class="constructor">Pervasives</span>.compare x0 x1 <span class="keyword">with</span>
0 <span class="keywordsign">-></span> <span class="constructor">Pervasives</span>.compare y0 y1
<span class="keywordsign">|</span> c <span class="keywordsign">-></span> c
<span class="keyword">end</span>
<span class="keyword">module</span> <span class="constructor">PairsMap</span> = <span class="constructor">Map</span>.<span class="constructor">Make</span>(<span class="constructor">IntPairs</span>)
<span class="keyword">let</span> m = <span class="constructor">PairsMap</span>.(empty |> add (0,1) <span class="string">"hello"</span> |> add (1,0) <span class="string">"world"</span>)
</code></pre>
<p>This creates a new module <code class="code"><span class="constructor">PairsMap</span></code>, with a new type <code class="code"><span class="keywordsign">'</span>a <span class="constructor">PairsMap</span>.t</code>
of maps from <code class="code">int * int</code> to <code class="code"><span class="keywordsign">'</span>a</code>. In this example, <code class="code">m</code> contains <code class="code">string</code>
values so its type is <code class="code">string <span class="constructor">PairsMap</span>.t</code>.</p>
