Public Methods

public void close ()

Close this LobCreator session and free its temporarily created BLOBs and CLOBs. Will not need to do anything if using PreparedStatement's standard methods, but might be necessary to free database resources if using proprietary means.

NOTE: Needs to be invoked after the involved PreparedStatements have been executed or the affected O/R mapping sessions have been flushed. Otherwise, the database resources for the temporary BLOBs might stay allocated.

public void setBlobAsBinaryStream (PreparedStatement ps, int paramIndex, InputStream binaryStream, int contentLength)

Set the given content as binary stream on the given statement, using the given parameter index. Might simply invoke PreparedStatement.setBinaryStream or create a Blob instance for it, depending on the database and driver.

Parameters
ps the PreparedStatement to the set the content on
paramIndex the parameter index to use
binaryStream the content as binary stream, or null for SQL NULL
Throws
SQLException

public void setBlobAsBytes (PreparedStatement ps, int paramIndex, byte[] content)

Set the given content as bytes on the given statement, using the given parameter index. Might simply invoke PreparedStatement.setBytes or create a Blob instance for it, depending on the database and driver.

Parameters
ps the PreparedStatement to the set the content on
paramIndex the parameter index to use
content the content as byte array, or null for SQL NULL
Throws
SQLException

public void setClobAsAsciiStream (PreparedStatement ps, int paramIndex, InputStream asciiStream, int contentLength)

Set the given content as ASCII stream on the given statement, using the given parameter index. Might simply invoke PreparedStatement.setAsciiStream or create a Clob instance for it, depending on the database and driver.

Parameters
ps the PreparedStatement to the set the content on
paramIndex the parameter index to use
asciiStream the content as ASCII stream, or null for SQL NULL
Throws
SQLException

public void setClobAsCharacterStream (PreparedStatement ps, int paramIndex, Reader characterStream, int contentLength)

Set the given content as character stream on the given statement, using the given parameter index. Might simply invoke PreparedStatement.setCharacterStream or create a Clob instance for it, depending on the database and driver.

Parameters
ps the PreparedStatement to the set the content on
paramIndex the parameter index to use
characterStream the content as character stream, or null for SQL NULL
Throws
SQLException

public void setClobAsString (PreparedStatement ps, int paramIndex, String content)

Set the given content as String on the given statement, using the given parameter index. Might simply invoke PreparedStatement.setString or create a Clob instance for it, depending on the database and driver.

Parameters
ps the PreparedStatement to the set the content on
paramIndex the parameter index to use
content the content as String, or null for SQL NULL
Throws
SQLException
