<P>
The declaration of the class <tt>ChainedScatterTable</tt> is given in
Program <A HREF="page231.html#proghashtbl3h" tppabs="http://dictator.uwaterloo.ca/Bruno.Preiss/books/opus4/html/page231.html#proghashtbl3h"><IMG ALIGN=BOTTOM ALT="gif" SRC="cross_ref_motif.gif" tppabs="http://dictator.uwaterloo.ca/Bruno.Preiss/books/opus4/icons/cross_ref_motif.gif"></A>.
The scatter table is implemented as an array
of elements of the nested type <tt>Entry</tt>.
Each <tt>Entry</tt> instance has two member variables--<tt>object</tt> and <tt>next</tt>.
The former is a pointer to a contained object.
The latter indicates the position in the array of the next element of a chain.
The value of the enumerated constant <tt>null</tt> will be used instead of zero
to mark the end of a chain.
The value zero is not used to mark the end of a chain
because zero is a valid array subscript.
