 <div class="refsect1" title="Description">
 <a name="glib-Sequences.description"></a><h2>Description</h2>
 <p>
 The <a class="link" href="glib-Sequences.html#GSequence" title="GSequence"><span class="type">GSequence</span></a> data structure has the API of a list, but is
 implemented internally with a balanced binary tree. This means that
 it is possible to maintain a sorted list of n elements in time O(n
 log n). The data contained in each element can be either integer
 values, by using of the <a class="link" href="glib-Type-Conversion-Macros.html" title="Type Conversion Macros">Type Conversion Macros</a>,
 or simply pointers to any type of data.
 </p>
 <p>
 A <a class="link" href="glib-Sequences.html#GSequence" title="GSequence"><span class="type">GSequence</span></a> is accessed through <em class="firstterm">iterators</em>,
 represented by a <a class="link" href="glib-Sequences.html#GSequenceIter" title="GSequenceIter"><span class="type">GSequenceIter</span></a>. An iterator represents a position
 between two elements of the sequence. For example, the
 <em class="firstterm">begin</em> iterator represents the gap immediately
 before the first element of the sequence, and the
 <em class="firstterm">end</em> iterator represents the gap immediately
 after the last element. In an empty sequence, the begin and end
 iterators are the same.
 </p>
 <p>
 Some methods on <a class="link" href="glib-Sequences.html#GSequence" title="GSequence"><span class="type">GSequence</span></a> operate on ranges of items. For example
 <a class="link" href="glib-Sequences.html#g-sequence-foreach-range" title="g_sequence_foreach_range ()"><code class="function">g_sequence_foreach_range()</code></a> will call a user-specified function on
 each element with the given range. The range is delimited by the
 gaps represented by the passed-in iterators, so if you pass in the
 begin and end iterators, the range in question is the entire
 sequence.
 </p>
 <p>
 The function <a class="link" href="glib-Sequences.html#g-sequence-get" title="g_sequence_get ()"><code class="function">g_sequence_get()</code></a> is used with an iterator to access the
 element immediately following the gap that the iterator represents.
 The iterator is said to <em class="firstterm">point</em> to that element.
 </p>
 <p>
 Iterators are stable across most operations on a <a class="link" href="glib-Sequences.html#GSequence" title="GSequence"><span class="type">GSequence</span></a>. For
 example an iterator pointing to some element of a sequence will
 continue to point to that element even after the sequence is sorted.
 Even moving an element to another sequence using for example
 <a class="link" href="glib-Sequences.html#g-sequence-move-range" title="g_sequence_move_range ()"><code class="function">g_sequence_move_range()</code></a> will not invalidate the iterators pointing
 to it. The only operation that will invalidate an iterator is when
 the element it points to is removed from any sequence.
