Detailed Description

template<class K, class D>
class WvGdbmHash< K, D >

This hashtable is different from normal WvStreams hashtables in that it stores the data on disk.

This affects memory management for objects stored in it.

For find and operator[], the returned object is only guaranteed to be around until the next find/or next() for iterators.
