|
||
<p>Sequence sorted by a key function.</p>
|
||
<p>SortedCollection() is much easier to work with than using bisect() directly.
|
||
It supports key functions like those use in sorted(), min(), and max().
|
||
The result of the key function call is saved so that keys can be searched
|
||
efficiently.</p>
|
||
<p>Instead of returning an insertion-point which can be hard to interpret, the
|
||
five find-methods return a specific item in the sequence. They can scan for
|
||
exact matches, the last item less-than-or-equal to a key, or the first item
|
||
greater-than-or-equal to a key.</p>
|
||
<p>Once found, an item’s ordinal position can be located with the index() method.
|
||
New items can be added with the insert() and insert_right() methods.
|
||
Old items can be deleted with the remove() method.</p>
|
||
<p>The usual sequence methods are provided to support indexing, slicing,
|
||
length lookup, clearing, copying, forward and reverse iteration, contains
|
||
checking, item counts, item removal, and a nice looking repr.</p>
|
||
<p>Finding and indexing are O(log n) operations while iteration and insertion
|
||
are O(n). The initial sort is O(n log n).</p>
|
||
<p>The key function is stored in the ‘key’ attibute for easy introspection or
|
||
so that you can assign a new key function (triggering an automatic re-sort).</p>
|
||
<p>In short, the class was designed to handle all of the common use cases for
|
||
bisect but with a simpler API and support for key functions.</p>
