Method Detail

clear

public void clear()

Description copied from class: IfxObject

Clear the instance states

Overrides:

clear in class IfxObject

fromIfx

public void fromIfx(byte[] b)
             throws java.sql.SQLException

fromIfx() convert network complex type data

Overrides:

fromIfx in class IfxObject

Parameters:

byte[] - byte array containing tuple data

Throws:

java.sql.SQLException

fromIfx

public void fromIfx(byte[] b,
                    int offset,
                    int length)
             throws java.sql.SQLException

fromIfx() convert network complex type data into a IfxColumnInfo [] to hold the type information based on the flag information determine if it's NULL instantiate a IfxComplexInput to hold the serialized data. Data isn't materialized until Struct.getAttribute, Array.toArray() or IfxRow.toObject() or IfxCollection.toObject() is called.

Overrides:

fromIfx in class IfxObject

Parameters:

byte[] - byte array containing tuple data

offset - position into byte array where data starts

length - size of data

Throws:

java.sql.SQLException

fromIfx

public void fromIfx(byte[] b,
                    IfxColumnInfo typeInfo,
                    boolean isNull)
             throws java.sql.SQLException

Throws:

java.sql.SQLException

toIfx

public byte[] toIfx()
             throws java.sql.SQLException

toIfx - called from one of IfxComplex's subclass'. The subclass is is reponsible for serializing the data information when fromObject() is called.

Overrides:

toIfx in class IfxObject

Parameters:

byte[] - byte array containing tuple data

Throws:

java.sql.SQLException

toIfxTuple

public byte[] toIfxTuple()
                  throws java.sql.SQLException

toIfxTuple - called from one of IfxComplex's subclass'. The subclass is is reponsible for serializing the data information when fromObject() is called.

Overrides:

toIfxTuple in class IfxObject

Parameters:

byte[] - byte array containing tuple data

Throws:

java.sql.SQLException
