Description

Interface Summary

BubbleMessage	A bubble message is a special data that feeds a context, to be used by a specific target.
ForeignAttribute	A foreign attribute is an XML attribute that is bound to a namespace URI, usually different from the element it belongs.
Names	Registered names and namespace URIs.
PropertyResolver	Implementations of this class are plugged in front of the data setto compute specific properties that are not stored within the data set.

Class Summary

Bootstrap	The Bootstrap class contains a registry and a catalog that are static and always available for any processor.
Bootstrap.PrimalCatalog	The PrimalCatalog is a hard-coded catalog that refers to all RefleX resources.
BubbleMessage.Impl	A default implementation.
ClassBuilder	Represents the builder that delivers instances for a specific QName on behalf of a module.
DataSet	A DataSet is used to store properties used by the RefleX processor at runtime.
DataSet.Embedded	An Embedded data set that can be stored safely (it can be reached with a permanent strong reference).
ForeignAttribute.Impl	A partial implementation of foreign attribute.
ForeignAttribute.Marker	A foreign attribute that is just a marker (does nothing).
Module	A module allows to group related Active Tags features together.
Module.DeferredModule	A module that unmarshals itself only when it is invoked.
ModuleBuilder	A ModuleBuilder creates a Module.
ModuleFinder	The lookup strategy for modules : top-down, registry before, interleave, rely on registry.
NoModule	A marker that denotes that no module were found.
ProcessorInstance	The processor instance is the active form of an Active Sheet.
PropertyResolver.Impl	A default implementation that does nothing.

Exception Summary

BreakException	This exception is thrown when a break action is encountered.
ContinueException	This exception is thrown when a continue action is encountered.
EngineCorruptedException	This exception occurs when a basic service of the engine fails, such as when the implementation of an XPath function is missing.
ExitException	This exception is thrown when an exit action is encountered.

Package org.inria.ns.reflex.processor Description

Provides core classes for the engine.

Once an XML active sheet is unmarshalled, it gives a processor instance.

The RefleX processor works in two steps :

• All actions are first read once from the XML file (the active sheet) and used to load actions classes.
• Then, the processor can be invoked by running it with a set of datas.

The processor is safe thread, thus several datas sets can be processed at the same time without causing fault.

When unmarshalling the active sheet, active materials are looked up within the catalog according to their namespace URIs. A bootstrap catalog contains all modules defined by this engine.

Each module found may define :

• XML elements, that are unmarshalled to action classes
• XML attributes, that are unmarshalled to foreign attributes classes
• properties, that are unmarshalled to predefined properties classes
• XPath functions, that are unmarshalled to extended XPath function classes

• Custom modules may be defined thanks to EXP
• The core active materials are in the package org.inria.ns.reflex.processor.core.
• The XML Control Language is in the package org.inria.ns.reflex.processor.xcl.
