These are autonomous software modules that use the base services functionality and may produce new messages that respond to initial requests or notify interested parties about a system event discount cafergot 100mg amex. The Controller implements a messaging pipeline using the SOAP protocol buy cafergot 100 mg on line, where messages are processed at each node of the Pipeline and forwarded to the next node. This involves authentication and authorization of the message sender, logging and tracing of all message flow within the system, applying business rules and dispatching the messages to the appropriate Action handlers. Copying or distributing in print or electronic forms without written permission of Idea Group Inc. For example, changes in business processes or operational workflows result in the need for exchanging new messages. New Action handlers can be implemented for processing these messages and the Controller can be easily configured to dispatch the appropriate message to the dedicated Action handler. The Presentation layer services of the framework contain a set of tools and methods targeting the development of adaptive XML-based user interface modules. Using these tools and methods one can assemble user interface modules from XML documents. Serializable non-visual Components: A user interface document contains also XML descriptions targeting non-visual components of the framework that also support XML serialization. These components undertake a set of operations such as sending and receiving documents to/from the Controller, sending and receiving documents to/from different devices, such as printers or file systems and trans- forming documents. A complete user interface module is a collection of objects capable of accepting and producing XML descriptions. New Xml objects can be created by anyone planning to extend the user interface infrastructure of the framework. The basic interface of an Xml object contains only three operations: the Describe operation supporting the initial definition and construction of the object based on an XML description, the LoadXml operation supporting the loading of an XML description from the object, and the Xml operation supporting the generation of an XML description by the object.
