DefaultLobHandler
public class DefaultLobHandler extends AbstractLobHandler (Code)
Default implementation of the LobHandler interface. Invokes the direct accessor methods that java.sql.ResultSet and java.sql.PreparedStatement offer.

This LobHandler should work for any JDBC driver that is JDBC compliant in terms of the spec's suggestions regarding simple BLOB and CLOB handling. This does not apply to Oracle 9i, and only to a limited degree to Oracle 10g! As a consequence, use OracleLobHandler for accessing Oracle BLOBs/CLOBs.

Method Detail
getBlobAsBinaryStream
public InputStream getBlobAsBinaryStream(ResultSet rs, int columnIndex) throws SQLException(Code)



getBlobAsBytes
public byte[] getBlobAsBytes(ResultSet rs, int columnIndex) throws SQLException(Code)



getClobAsAsciiStream
public InputStream getClobAsAsciiStream(ResultSet rs, int columnIndex) throws SQLException(Code)



getClobAsCharacterStream
public Reader getClobAsCharacterStream(ResultSet rs, int columnIndex) throws SQLException(Code)



getClobAsString
public String getClobAsString(ResultSet rs, int columnIndex) throws SQLException(Code)



getLobCreator
public LobCreator getLobCreator()(Code)



setStreamAsLob
public void setStreamAsLob(boolean streamAsLob)(Code)
Specify whether a submitted binary stream / character stream should be passed to the JDBC driver as explicit LOB content, using the JDBC 4.0 setBlob / setClob method with a stream argument.

Default is "false", using the common JDBC 2.0 setBinaryStream / setCharacterStream method for setting the content. Switch this to "true" for explicit JDBC 4.0 usage, provided that your JDBC driver actually supports those JDBC 4.0 operations.
