Interface LobStreamInterface

All Superinterfaces:

BlobDomainInterface, DomainInterface, LobInterface, MutableDomainInterface

public interface LobStreamInterface

extends LobInterface

Provides methods to save data to, and extract data from, LOB domain classes. These methods are implemented by all LOB-based domain classes: BlobDomain, BFileDomain, and ClobDomain.

Domain classes encapsulate Oracle SQL datatypes. Domain objects can be converted to the standard JDBC data types.

Since:

JDevloper 3.0

Method Detail

getOutputStream

public java.io.OutputStream getOutputStream()

Returns a stream to be used to write bytes into this LOB. This stream works in both 2/3 tiers. In 2-tier, this stream could be the same as the stream returned by the internal jdbc object. In 3-tier, this stream is a remote OutputStream that streams data from the middle-tier LOB.

closeOutputStream

public void closeOutputStream()

Closes and cleansup internal reference to output stream.

getInputStream

public java.io.InputStream getInputStream()

Returns a stream to be used to read bytes from this LOB. This stream works in both 2/3 tiers. In 2-tier, this stream could be the same as the stream returned by the internal jdbc object. In 3-tier, this stream is a remote OutputStream that streams data from the middle-tier LOB.

getCharacterStream

public java.io.Reader getCharacterStream()

Returns a stream to be used to read bytes from this LOB. This stream works in both 2/3 tiers. In 2-tier, this stream could be the same as the stream returned by the internal jdbc object. In 3-tier, this stream is a remote OutputStream that streams data from the middle-tier LOB.
