Interface IfmxUDTSQLInput

public interface IfmxUDTSQLInput

The IfmxUDTSQLInput interface extends the SQLInput interface. This interface is specifically for Informix user-defined types. It contains Informix extension methods for materializing fixed-length data.

Method Summary

Modifier and Type	Method and Description
int	available() Returns the number of bytes remaining in this input stream
boolean	getAutoAlignment() Returns true if auto alignment is enabled and false if auto alignment has been disabled.
int	getCurrentPosition() Returns the current position in the input stream.
IfxUDTInfo	getUDTInfo(int xid) Get general information about opaque and distinct types and detailed information for complex types.
IfxUDTInfo	getUDTInfo(java.lang.String name, java.lang.String owner) Get general information about opaque and distinct types and detailed information for complex types.
byte[]	readAllBytes() Returns the entire UDT structure as a byte [] It is up to the end user then to convert this into the appropriate structure for the UDT
void	setAutoAlignment(boolean value) Enable or disable automatic alignment.
void	setCurrentPosition(int position) Sets the current position.
void	skipBytes(int len) Skips over and discards len bytes of data from the input stream.

Method Detail

setAutoAlignment

void setAutoAlignment(boolean value)

Enable or disable automatic alignment. The default is that the driver automatically handles alignment between data fields.

Parameters:

value - = true then alignment should be handles automatically. If value = false then no alignment is done. It's the user's respon- sibility to call skipBytes(int) to handle alignment.

getAutoAlignment

boolean getAutoAlignment()

Returns true if auto alignment is enabled and false if auto alignment has been disabled.

Returns:

true if auto alignment is enabled.

skipBytes

void skipBytes(int len)
        throws java.sql.SQLException

Skips over and discards len bytes of data from the input stream. alignment has been disabled.

Parameters:

len - Number of bytes to skip over and discard.

Throws:

java.sql.SQLException

getCurrentPosition

int getCurrentPosition()

Returns the current position in the input stream.

Returns:

Returns the current position.

setCurrentPosition

void setCurrentPosition(int position)
                 throws java.sql.SQLException

Sets the current position.

Parameters:

position -

Throws:

java.sql.SQLException

available

int available()

Returns the number of bytes remaining in this input stream

Returns:

Returns the number of bytes remaining in this input stream.

getUDTInfo

IfxUDTInfo getUDTInfo(int xid)
               throws java.sql.SQLException

Get general information about opaque and distinct types and detailed information for complex types. Calls IfmxConnection.getUDTInfo(int)

Parameters:

xid - Is the extended id found in sysxtdtype system catalog.

Returns:

Object of type IfxUDTInfo which contains all information about a user defined datatype

Throws:

java.sql.SQLException

getUDTInfo

IfxUDTInfo getUDTInfo(java.lang.String name,
                      java.lang.String owner)
               throws java.sql.SQLException

Get general information about opaque and distinct types and detailed information for complex types. Calls IfmxConnection.getUDTInfo(String name, String owner)

Parameters:

name - The data type name.

owner - The owner of the data type (can be null).

Returns:

The detailed type information as an Informix IfxUDTInfo.

Throws:

java.sql.SQLException

readAllBytes

byte[] readAllBytes()
             throws java.sql.SQLException

Returns the entire UDT structure as a byte [] It is up to the end user then to convert this into the appropriate structure for the UDT

Returns:

byte [] the UDT structure as a byte array

Throws:

java.sql.SQLException
