java.lang.Object
oracle.jbo.domain.BaseLobDomain
oracle.jbo.domain.BlobDomain
This class provides a lightweight wrapper for oracle.sql.BLOB, the Java representation of the BLOB database type. This wrapper allows an instance of the oracle.sql.BLOB to be used as a domain object.
Constructor Summary | |
BlobDomain() Constructor for this object. |
|
BlobDomain(BLOB blob) Constructor for this object. |
|
BlobDomain(BLOB blob, byte[] blobData) Creates an instance of this class with data as described in blobData and using the transaction context from blob to use the blob-locator in the database. |
Method Summary | |
void |
closeCharacterOutputStream() |
static BLOB |
createEmptyBLOB(java.lang.Object context) Creates an empty Blob object. |
boolean |
equals(java.lang.Object obj) Tests for equality between this and obj. |

Node |
getXMLContentNode(Document xmlDoc) Creates the XML node in the given XML document for this domain's data. |
static XMLDomainFactory |
getXMLDomainFactory(java.lang.Class attrClass) Internal: Applications should not use this method. |
protected java.lang.String |
getXMLElementTag() Returns this class name as an XML-element tag for this Struct domain object. |
void |
prepareForDML(java.lang.Object context) Internal: Applications should not use this method. |
java.lang.String |
printXMLDefinition(java.util.Hashtable allDefs, java.io.PrintWriter pw, boolean bContainees) Prints the DTD information for this domain in the given print writer. |
