| <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 "iterators", 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 "begin" iterator |
| represents the gap immediately before the first element of the |
| sequence, and the "end" 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 "point" 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.</p> |
