| CustomStringPool is an example of appliction provided data structure
for a DTM implementation to hold symbol references, e.g. elelment names.
It will follow the DTMDStringPool interface and use two simple methods
indexToString(int i) and stringToIndex(Sring s) to map between a set of
string values and a set of integer index values. Therefore, an application
may improve DTM processing speed by substituting the DTM symbol resolution
tables with application specific quick symbol resolution tables.
%REVIEW% The only difference between this an DTMStringPool seems to be that
it uses a java.lang.Hashtable full of Integers rather than implementing its
own hashing. Joe deliberately avoided that approach when writing
DTMStringPool, since it is both much more memory-hungry and probably slower
-- especially in JDK 1.1.x, where Hashtable is synchronized. We need to
either justify this implementation or discard it.
Status: In progress, under discussion.
