getStreamFromBO()

Serializes a business object into an InputStream object.

Syntax

abstract InputStream getStreamFromBO(BusinessObjectInterface theBusObj,
       Object config);
 

Parameters

theBusObj
Business object to be converted to a stream.
config
Optional object containing additional configuration information for the data handler.

Return values

An InputStream object containing serialized data representing a business object.

Exceptions

Exception
Thrown if the method cannot convert the business object to a stream of serialized data.

Notes

The getStreamFromBO() method performs business-object-to-stream conversion for a data handler. It converts the data in the theBusObj business object into a stream (a Java InputStream object).

Important:
The getStreamFromBO() method is an abstract method that has no default implementation.Therefore, the data handler class must implement this method.

If you need to provide your data handler with more configuration information than is included in the meta-object, you can use the config option to pass in an object that contains this information. For example, config could be a template file or a string to a URL for a schema that is used to build an XML document from a business object.

If config is a business object type, you can implement the getStreamFromBO() method to call setupOptions(config). The setupOptions() method is defined in the DataHandler base class. This method uses the attribute names in the business object as property names and the default values as the values for those properties. It sets the values of the configuration properties in the object for use by the data handler.
