The TQIntCacheIterator class provides an iterator for <a href="tqintcache.html">TQIntCache</a> collections.
|
||
|
13 years ago
|
<p>
|
||
|
|
|
||
|
|
<p> Note that the traversal order is arbitrary; you are not guaranteed
|
||
|
|
any particular order. If new objects are inserted into the cache
|
||
|
|
while the iterator is active, the iterator may or may not see
|
||
|
|
them.
|
||
|
|
<p> Multiple iterators are completely independent, even when they
|
||
|
|
operate on the same TQIntCache. TQIntCache updates all iterators
|
||
|
|
that refer an item when that item is removed.
|
||
|
|
<p> TQIntCacheIterator provides an <a href="#operator++">operator++</a>(), and an <a href="#operator+-eq">operator+=</a>() to
|
||
|
|
traverse the cache; <a href="#current">current</a>() and <a href="#currentKey">currentKey</a>() to access the
|
||
|
|
current cache item and its key; <a href="#atFirst">atFirst</a>() <a href="#atLast">atLast</a>(), which return
|
||
|
|
TRUE if the iterator points to the first/last item in the cache;
|
||
|
|
<a href="#isEmpty">isEmpty</a>(), which returns TRUE if the cache is empty; and <a href="#count">count</a>(),
|
||
|
|
which returns the number of items in the cache.
|
||
|
|
<p> Note that atFirst() and atLast() refer to the iterator's arbitrary
|
||
|
|
ordering, not to the cache's internal least recently used list.

</h3>
|

|
|
|
||
|
|
<p> Constructs an iterator for <em>cache</em>. The current iterator item is
|
||
|
|
set to point to the first item in the <em>cache</em> (or rather, the
|
||
|
|
first item is defined to be the item at which this constructor
|
||
|
|
sets the iterator to point).

|
</h3>
|
||
|
|
|
||
|
|
<p> Constructs an iterator for the same cache as <em>ci</em>. The new

independently from there on.

<p> Returns TRUE if the iterator points to the first item in the

cache; otherwise returns FALSE. Note that this refers to the

|
iterator's arbitrary ordering, not to the cache's internal least

otherwise returns FALSE. Note that this refers to the iterator's

arbitrary ordering, not to the cache's internal least recently

<p> Prefix ++ makes the iterator point to the item just after
