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

public BFileDomain()
public BFileDomain(BFILE bFile)
bFile
- name of a BFILE object.public BFileDomain(BFILE bFile, byte[] bFileData)
Creates an instance of this class with data as described in bFileData
and using the transaction context from bFile
to use the file-locator in the database.
bFile
- the name of the BFILE.bFileData
- the data for the BFILE.public BFileDomain(BFileDomain bFile, byte[] bFileData)
bFileData
and using the transaction context from bFile
to use the file-locator in the database.
This constructor should be used by applications using the framework to create BFileDomain objects.
bFile
- the name of the BFILE.bFileData
- the data forthe BFILE.Method Detail |
---|
public void shareBFILE(BFileDomain newBFile)
If this object does not have a transaction context, shares the transaction and BFILE locator from newBfile
.
newBFile
- name of the BFILE with which this BFILE will share its transaction and file locator information.public void useBFILE(BFILE newBlob)
If this object does not have a transaction context, shares the transaction and BFILE locator from newBfile
.
newBlob
- name of the BFILE with which this BFILE will share its transaction and BFILE locator information.public void setBytes(byte[] bFileData) throws DomainValidationException
bFileData
- the data used to fill the BFILE.DomainValidationException
- if domain creation fails.public void loadFromDatabase(Transaction xAct) throws java.lang.Exception
Uses the given transaction context to load data from the database.
loadFromDatabase
in interface BlobDomainInterface
xAct
- the name of the transaction to use.java.lang.Exception
public void setContext(DomainOwnerInterface owner, Transaction trans, java.lang.Object ctx)
Sets the transaction context for this BFILE.
setContext
in interface DomainInterface
public java.lang.Object getData()
Returns a BFILE
that contains data for this object.
getData
in interface DomainInterface
public void saveToDatabase(Transaction xAct) throws java.lang.Exception
NOT IMPLEMENTED FOR 3.0 Uses the given transaction context to store data back into the database using the BFILE locator which should be set before this method is invoked.
saveToDatabase
in interface BlobDomainInterface
xAct
- the name of the transaction.java.lang.Exception
public void saveToDatabase(Transaction xAct, java.lang.Object emptySQLObject) throws java.sql.SQLException
NOT IMPLEMENTED FOR 3.0 Uses the given transaction context to store data back into the database using the BFILE locator which should be set before this method is invoked.

obj
- the object to compare to this BfileDomain.public java.io.OutputStream getOutputStream()
LobStreamInterface
Note that calling this multiple times returns the same OutputStream object. (It does not create a new OutputStream object each time it is called.) If you want to get a new OutputStream, call closeOutputStream then call getOutputStream.
