SQLOutput
interface SQLOutput
java.sql.SQLOutput |
The output stream for writing the attributes of a user-defined type back to the database. This interface, used only for custom mapping, is used by the driver, and its methods are never directly invoked by a programmer.
When an object of a class implementing the interface SQLData
is passed as an argument to an SQL statement, the JDBC driver calls the method SQLData.getSQLType
to determine the kind of SQL datum being passed to the database. The driver then creates an instance of SQLOutput
and passes it to the method SQLData.writeSQL
. The method writeSQL
in turn calls the appropriate SQLOutput
writer methods writeBoolean
, writeCharacterStream
, and so on) to write data from the SQLData
object to the SQLOutput
output stream as the representation of an SQL user-defined type.

writeObject
abstract fun writeObject(x: SQLData!): Unit

method of the given object, which writes the object's attributes to the stream. The implementation of the method SQLData.writeSQ
calls the appropriate SQLOutput

input stream and written to an SQLOutput
output stream in the same order in which they were listed in the SQL definition of the user-defined type.
