public interface SQLUDTOutput
extends java.sql.SQLOutput

JDBC 2.0 This SQLUDTOutput interface extends from SQLOutput. This interface is specificly used for Informix User Defined Types. It contains Informix extension methods for serializing/deserializing fixed length data.

Method Summary

Methods

Modifier and Type	Method and Description
void	writeBytes(byte[] b, int length) Write the next attribute to the stream as a Java byte array.
void	writeInterval(Interval intrvl) Write the next attribute to the stream as a Java Interval.
void	writeString(java.lang.String x, int length) Write the next attribute to the stream as a Java String.

Method Detail

writeString

void writeString(java.lang.String x,
               int length)
                 throws java.sql.SQLException

Write the next attribute to the stream as a Java String. This method is similar to SQLOutput.writeString() with the exception that a fixed length of data is written to the stream. If the String passed in is shorter then the destinated length, the driver will zero pad the string. This method replaces SQLOutput.writeString() in the UDT implementation since the user defined type is unknown to the driver, the user MUST supply a length in order for the driver to write the next attribute properly.

Parameters:

x - the value to pass to the database

length - the length of the destinated field

Throws:

java.sql.SQLException

writeBytes

void writeBytes(byte[] b,
              int length)
                throws java.sql.SQLException

Write the next attribute to the stream as a Java byte array. This method is similar to SQLOutput.writeBytes() with the exception that a fixed length of data is written to the stream. If the array passed in is shorter then the destinated length, the driver will zero pad the array. This method replaces SQLOutput.writeBytes() in the UDT implementation since the user defined type is unknown to the driver, the user MUST supply a length in order for the driver to write the next attribute properly.

Parameters:

x - the value to pass to the database

length - the length of the destinated field

Throws:

java.sql.SQLException

writeInterval

void writeInterval(Interval intrvl)
                   throws java.sql.SQLException

Write the next attribute to the stream as a Java Interval. This method is an Informix extension.

Parameters:

intrvl - the interval pass to the database

Throws:

java.sql.SQLException
