Class OrdVideoDomain

oracle.ord.im.OrdVideoDomain

All Implemented Interfaces:

OrdDomainIOInterface, OrdDomainState, java.io.Serializable

public class OrdVideoDomain

implements OrdDomainIOInterface, OrdDomainState, java.io.Serializable

Represents interMedia ORDSYS.ORDVideo database type as a domain class in the Business Components 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
• getComments
• setComments
• getAllAttributes
• getContentInLob

The BC4J tier-independent counterparts of the first three methods are the following:

• getContentAsBlobDomain
• getBFileDomain
• getCommentsAsClobDomain

There are no corresponding BC4J tier-independent methods for setComments, getAllAttributes and getContentInLob.

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 OrdVideoDomain. 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.

Constructor Detail

OrdVideoDomain

public OrdVideoDomain()

Constructs a new OrdVideoDomain instance. Before it's been inserted into the database table and selected back, this new instance doesn't have a JDBC connection to the database. It also doesn't have a corresponding existing database ORDSYS.ORDVideo object.

OrdVideoDomain

public OrdVideoDomain(byte[] bytes)

Constructs a new OrdVideoDomain instance. Before it has been inserted into the database table and selected back; this new instance doesn't have a JDBC connection to the database. It also doesn't have a corresponding existing database ORDSYS.ORDVideo object. Users should use deferred loading to load the video content into the database.

Calling this constructor has the same effect of calling the following two statements.

Parameters:

bytes - the byte array that contains the video content

See Also:

Constructs a new OrdVideoDomain instance. Before it has been inserted into the database table and selected back; this new instance doesn't have a JDBC connection to the database. It also doesn't have a corresponding existing database ORDSYS.ORDVideo object. Users should use deferred loading to load the video content into the database.

Calling this constructor has the same effect of calling the following two statements.

     OrdVideoDomain video = new OrdVideoDomain();

OrdContentSource, OrdFileSource

OrdVideoDomain

public OrdVideoDomain(OrdHttpUploadFile ohuf)

Constructs a new OrdVideoDomain instance. Before it has been inserted into the database table and selected back; this new instance doesn't have a JDBC connection to the database. It also doesn't have a corresponding existing database ORDSYS.ORDVideo object. Users should use deferred loading to load the video content into the database.

setProperties

public void setProperties()
                   throws java.sql.SQLException

Parses the video data properties and sets the attributes in the OrdVideoDomain Java object. This method sets the format, mimeType, width, height, frameResolution, frameRate, videoDuration, numberOfFrames, compressionType, numberOfColors, and bitRate attributes. An attribute is set to null if the corresponding property cannot be extracted for a specific video format. This method throws a SQLException if the video format is not recognized.

Note

The format attribute determines which format plug-in is used to parse the video data properties. If the format attribute is null when setProperties is called, then the default, Oracle-supplied, format plug-in is used to parse the video data properties and fill in various attributes, including the actual video data format, for supported video formats. See Oracle interMedia User's Guide and Reference for information on the video formats supported by the Oracle-supplied format plug-ins. Note that the ORDVideo.init methods in the database always set the format attribute to null. If the format attribute is not null, then the format plug-in specified by the format attribute will be called when setProperties is called.

Note

If the user supplied format plug-in requires a context, the user should use setProperties(byte[][]) or setProperties(byte[][], boolean) instead of this method. Otherwise, this method may fail.

Throws:

java.sql.SQLException - if an error occurs while executing the corresponding setProperties method in the database
