Knut Anders Hatlen updated DERBY-1527:
--------------------------------------
Derby Info: [Patch Available]
> Factor out type checks in EmbedResultSet and EmbedPreparedStatement
> -------------------------------------------------------------------
>
> Key: DERBY-1527
> URL: http://issues.apache.org/jira/browse/DERBY-1527
> Project: Derby
> Issue Type: Improvement
> Components: JDBC
> Affects Versions: 10.2.0.0
> Reporter: Knut Anders Hatlen
> Assigned To: Knut Anders Hatlen
> Priority: Minor
> Attachments: derby-1527-v1.diff, derby-1527-v1.stat
>
>
> EmbedPreparedStatement and EmbedResultSet have many occurrences of
> switch (...) {
> case Types.CHAR:
> case Types.VARCHAR:
> case Types.LONGVARCHAR:
> case Types.CLOB:
> break;
> default:
> throw dataTypeConversion(...);
> }
> and
> switch (...) {
> case Types.BINARY:
> case Types.VARBINARY:
> case Types.LONGVARBINARY:
> case Types.BLOB:
> break;
> default:
> throw dataTypeConversion(...);
> }
> Instead of having many copies of this code, it would be good to factor
> it out into methods that can be shared. For instance, one could add
> these methods to DataTypeDescriptor:
> public static boolean isAsciiStreamCompatible(int jdbcType)
> public static boolean isBinaryStreamCompatible(int jdbcType)
> public static boolean isCharacterStreamCompatible(int jdbcType)
