com.bea.wli.sb.sources
Class JavaObjectSource

java.lang.Object
com.bea.wli.sb.sources.JavaObjectSource

All Implemented Interfaces:

Source, java.io.Serializable

public class JavaObjectSource

extends java.lang.Object

implements Source, java.io.Serializable

A JavaObjectSource represents payload carried by the services that support OSB service binding type: Messaging Type : Java.

The objects that comprise this payload will be registered in pipeline java object repository by the binding layer and their contents will be visible in message context variables through <ctx:java-content ref='jcid:xyz' xmlns:ctx="http://www.bea.com/wli/sb/context" /> XML elements. Here, ref points to a unique id with which the object is stored within the java object repository.

Example:

Let’s assume, we have an inbound service with binding type: Messaging Type : java. When a transport invocation occurs and a JavaObjectSource is composed by the inbound endpoint with a single object say Obj1, the message payload in the pipeline will be represented as:

 <ctx:java-content ref='key1' xmlns:ctx="http://www.bea.com/wli/sb/context" />
 

In this example, the pipeline java object repository will contain:

key1 --> Obj1 .

Constructor Detail

JavaObjectSource

public JavaObjectSource(java.lang.Object... args)

Creates an instance of JavaObjectSource given a sequence of objects. Each object is expected to implement java.io.Serializable interface.

Parameters:

args - the sequence of objects to be registered in pipeline java object repository.

Method Detail

writeTo

public void writeTo(java.io.OutputStream os,
                    TransformOptions options)
             throws java.io.IOException,
                    TransformException

Writes the contents of this source by wrapping OutputStream argument with java.io.ObjectOutputStream and serializing all objects into it.

Specified by:

writeTo in interface Source

Parameters:

os - the OutputStream to which serialized content will be written

options - TransformOptions used to affect the serialization

Throws:

java.io.IOException

TransformException

getInputStream

public java.io.InputStream getInputStream(TransformOptions options)
                                   throws java.io.IOException,
                                          TransformException

Returns an input stream that contains serialized representation of all objects in this source. The result of this method should be wrapped with java.io.ObjectInputStream in order to read individual objects

Specified by:

getInputStream in interface Source

Parameters:

options - Options used to affect the serialization

Returns:

a InputStream for retrieving the serialized content

Throws:

java.io.IOException

TransformException

getObjects

public java.lang.Object[] getObjects()

Returns all the objects in this source.

Returns:

all the objects in this source or empty array if no objects are available with this source
