java.lang.Object
oracle.jbo.domain.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.

Constructor Detail |
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.
bFileData
- the data for the 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
.
public void useBFILE(BFILE newBlob)
If this object does not have a transaction context, shares the transaction and BFILE locator from newBfile
.
public void setBytes(byte[] bFileData) throws DomainValidationException
bFileData
- the data used to fill the BFILE.oracle.jbo.domain.DomainValidationException
- if domain creation fails.DomainValidationException
public void loadFromDatabase(Transaction xAct) throws java.lang.Exception
Uses the given transaction context to load data from the database.
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.
public java.lang.Object getData()
Returns a BFILE
that contains data for this object.
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.
