This class wraps around a set containing integer numbers.

Sets can also be iterated over with <link linkend="control-structures.foreach"><literal>foreach</literal></link> as the <interfacename>Iterator</interfacename> interface is
implemented as well. The order of which elements are returned in is not
guaranteed.

<para>If enabled, adding duplicate elements to a set (through either <methodname>QuickHashIntSet::add</methodname> or
<methodname>QuickHashIntSet::loadFromFile</methodname>) will result in those elements to be dropped from the
set. This will take up extra time, so only used when it is required.</para>

<listitem>
<para>Disables the use of PHP's internal memory manager for internal
set structures. With this option enabled, internal allocations will not
count towards the <link linkend="ini.memory-limit">memory_limit</link> settings.</para>

<para>Selects to not use a hashing function, but merely use a modulo to
find the bucket list index. This is not faster than normal hashing, and
gives more collisions.</para>
