Hi,
This is a request for review of
http://cr.openjdk.java.net/~lancea/8001536/webrev.00/. This adds
read/writeObject as well as clone methods to SerialXLob classes.
All SQE tests passed, 1 failure in the RowSet JCK/TCK tests due to a bug in
the test that the TCK team is aware of and will address. JDBC Unit tests all
pass .
Hi Lance.
In SerialBlob and in SerialClob
test (obj == null) is not necessary in equals, null instanceof X is
always false.
in hashCode, Objects.hash() allocate an array to pass arguments to
Arrays.hashCode() and box primitive values to Object.
while this method is really convenient to use, each calls will allocate
an array and box the two values,
the overhead seems to high here.
This code should be equivalent:
return ((31 +Arrays.hashCode(buf)) * 31 +len) * 31 + origLen;
in clone, sb should not be initialized to null and the catch should be:
throw new InternalError(e),
this is the standard code you can see in clone.
in readObject, the test (buf.length != len) can be done before decoding
the blob.
in writeObject, you set "blob" twice, which is weird, also I think that
if blob is not Serializable,
the code should throw an exception, so you should not use instanceof and
let s.writeFields()
to throw NotSerializable exception.
cheers,
Rémi
