oracle.jbo.domain
Class ClobDomain

oracle.jbo.domain.ClobDomain

All Implemented Interfaces:

java.io.Serializable

public class ClobDomain

implements java.io.Serializable

This class provides a lightweight wrapper for oracle.sql.Clob, the Java representation of the CLOB database type. This wrapper allows an instance of the oracle.sql.Clob to be used as a domain object.

Since:

JDeveloper 3.0

Constructor Detail

ClobDomain

public ClobDomain()

Constructor for this class.

ClobDomain

public ClobDomain(java.lang.String str)

Constructs an instance of this class, given a string.

Parameters:

a - string to be used for a ClobDomain.

ClobDomain

public ClobDomain(byte[] data)

Constructs an instance of this class, given a byte array.

Parameters:

a - byte array to be used for a ClobDomain.

ClobDomain

public ClobDomain(CLOB clob)

Constructs an instance of this class, given a CLOB object.

Parameters:

a - CLOB to be used for a ClobDomain.

ClobDomain

public ClobDomain(CLOB clob,
                  byte[] clobData)

Internal: Applications should not use this constructor.

Creates an instance of this class with data as described in clobData and using the transaction context from clob to use the CLOB locator in the database.

Parameters:

clob - name of the CLOB to use as a ClobDomain.

clobData - data to fill the CLOB.

ClobDomain

public ClobDomain(ClobDomain nclob,
                  byte[] clobData)

Creates an instance of this class with data as described in clobData and using the transaction context from clob to use the clob-locator in the database.

This constructor should be used by applications using the framework to create ClobDomain objects.

Parameters:

clob - name of the CLOB to use as a ClobDomain.

clobData - data to fill the CLOB.

Method Detail

useCLOB

public void useCLOB(CLOB newClob)

Internal: Applications should not use this method.

If this object does not have a transaction context, shares the transaction and CLOB locator from newClob.

Parameters:

newClob - name of the CLOB with which this CLOB will share its transaction and CLOB locator information.

prepareForDML

public void prepareForDML(java.lang.Object context)

Internal: Applications should not use this method.

equals

public boolean equals(java.lang.Object obj)

Converts all the data into a String and compares the two strings. This is a default implementation of equals which could be overridden to perform more scalable application-specific comparision.

Parameters:

obj - the object to compare to this ClobDomain.

getXMLDomainFactory

public static oracle.jbo.domain.XMLDomainFactory getXMLDomainFactory(java.lang.Class attrClass)

Internal: Applications should not use this method.

createEmptyCLOB

public static CLOB createEmptyCLOB(java.lang.Object context)

Creates an empty Blob object.

Parameters:

context - an internal framework context.

getSubString

public java.lang.String getSubString(long offset,
                                     int length)

getAsciiStream

public java.io.InputStream getAsciiStream()

getCharacterOutputStream

public java.io.Writer getCharacterOutputStream()

getCharacterStream

public java.io.Reader getCharacterStream()

getLength

public long getLength()

getBufferSize

public int getBufferSize()
