oracle.ord.im
Class OrdImageDomain

oracle.ord.im.OrdImageDomain

All Implemented Interfaces:

OrdDomainIOInterface, OrdDomainState, java.io.Serializable

public class OrdImageDomain

implements OrdDomainIOInterface, OrdDomainState, java.io.Serializable

Represents interMedia ORDSYS.ORDImage database type as a domain class in the Business Component for Java (BC4J) framework. Most methods in this class are BC4J tier independent. They can work on either the client tier or the middle tier, which allows the application which uses these methods to work in a tier independent fashion. There are some exceptions which are marked as local mode only:

• getContent
• getBFILE

The BC4J tier independent counterparts of these two methods are the following:

• getContentAsBlobDomain
• getBFileDomain

The term client tier refers to the machine on which the application client is running. Middle tier refers to the server on which the BC4J business components are deployed. The user can use "local mode only" methods when he deploys BC4J and the client application to the same machine. Whereas, the user should use tier independent methods when the application client and BC4J reside on separate machines.

The constructor for this class will create an instance of an OrdImageDomain. The user should either manually obtain a valid BLOB locator and a JDBC connection for this instance, or rely on the BC4J framework to obtain a BLOB locator and a JDBC connection for it. See OrdContentSource for discussion about how to load media content to the database by using the interMedia BC4J domain classes.

setContentSource

public void setContentSource(OrdContentSource source)

Description copied from interface: OrdDomainIOInterface

Sets the content source for deferred loading. Three predefined content source implementations support loading content from a file, a byte array, or a OrdHttpUploadFile object.

If the source parameter is null, this method just resets the previously set content source.

Specified by:

setContentSource in interface OrdDomainIOInterface

Following copied from interface: oracle.ord.im.OrdDomainIOInterface

Parameters:

source - the content source for the deferred loading
