Set the new pointer to a <a class="el" href="classPSafeObject.html">PSafeObject</a>. This will set the pointer to the new object. The old object pointed to will be unlocked and dereferenced and the new object referenced.
<p>
If the safe pointer has an associated collection and the new object is in that collection, then the object is set to the same locking mode as the previous pointer value. This, in effect, jumps the enumeration of a collection to the specifed object.
<p>
If the safe pointer has no associated collection or the object is not in the associated collection, then the object is always only referenced and there is no read only or read/write lock done. In addition any associated collection is removed so this becomes a non enumerating safe pointer.     </td>
