public interface SQLUDTInput
extends java.sql.SQLInput

JDBC 2.0

This SQLUDTInput interface extends from SQLInput. This interface is specificly used for Informix User Defined Types. It contains Informix extension methods for serializing/deserializing fixed length data.

Method Summary

Modifier and Type	Method and Description
int	length() Get the total length of the entire data stream.
byte[]	readBytes(int maxlen) Read the next attribute in the stream as Java byte array.
Interval	readInterval() Read the next attribute in the stream as a Java Interval.
java.lang.String	readString(int maxlen) Read the next attribute in the stream as a Java String.

Method Detail

length

int length()

Get the total length of the entire data stream.

Returns:

the total length.

readString

java.lang.String readString(int maxlen)
                     throws java.sql.SQLException

Read the next attribute in the stream as a Java String. This method is similar to SQLInput.readString() with the exception that a fixed length of data is read in. This method replaces SQLInput.readString() 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 read in the next attribute properly.

Parameters:

maxlen - the maximum size of data to read in.

Returns:

the attrubute as String.

Throws:

java.sql.SQLException

readBytes

byte[] readBytes(int maxlen)
          throws java.sql.SQLException

Read the next attribute in the stream as Java byte array. This method is similar to SQLOutput.readBytes() with the exception that a fixed length of data is read in. This method replaces SQLInput.readBytes() 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 read in the next attribute properly.

Parameters:

maxlen - the maximum size of data to read in.

Returns:

the attrubute as byte array.

Throws:

java.sql.SQLException

readInterval

Interval readInterval()
               throws java.sql.SQLException

Read the next attribute in the stream as a Java Interval. This method is an Informix extension.

Returns:

the attrubute as Interval object.

Throws:

java.sql.SQLException
