Subject Re: [simplestore] what Exceptions do we need?
Date Thu, 24 Jan 2002 10:56:59 GMT

1."ServiceNotAvailableException" is useful to handle fatal erros, "Log 
message,send SNS for admin .... "

2."NotFoundException" <==> "KeyNotFoundException" is useful to optimize 
"get" without   "contais" and for null result, nul is also "good" value.

3."KeyNotUniqueException" <==> "DublicateKeyException" is usefull for 
"put", because it returns "void" and  store can be used without "contais".

all of them not useful for memory stores, because they use Map for internal 
optimizations and in case "ServiceNotAvailableException" it impossible to 
handle, handling will fail :)
But for stores like "JDBCStore", "FileStore", "RemoteStore" exceptions are 
very useful.
