Store is like a hashtable - it supports getting, putting, removing and listing of elements. Elements may be stored or retrieved in three different formats: ByteArray, Value or Streams. Note that format information is not stored along with content, meaning that code must read and write information using the same format.<P><P><DL><DT><B>See Also:</B><DD><A
