There are two orthogonal sets of modes that can be set:
</para>
<itemizedlist>
<listitem>
<simpara>The direction of the iteration (either one or the other):</simpara>
<itemizedlist>
<listitem><simpara><constant>SplDoublyLinkedList::IT_MODE_LIFO</constant> (Stack style)</simpara></listitem>
<listitem><simpara><constant>SplDoublyLinkedList::IT_MODE_FIFO</constant> (Queue style)</simpara></listitem>

<listitem>
<simpara>The behavior of the iterator (either one or the other):</simpara>
<itemizedlist>
<listitem><simpara><constant>SplDoublyLinkedList::IT_MODE_DELETE</constant> (Elements are deleted by the iterator)</simpara></listitem>
<listitem><simpara><constant>SplDoublyLinkedList::IT_MODE_KEEP</constant> (Elements are traversed by the iterator)</simpara></listitem>
</itemizedlist>
</listitem>
</itemizedlist>
<para>
The default mode is: <constant>SplDoublyLinkedList::IT_MODE_FIFO</constant> | <constant>SplDoublyLinkedList::IT_MODE_KEEP</constant>
