Package wt.ixb Description

Provides classes to support import and export functionality, including the special case of archive and restore from archive.

Design

The following figure shows the essential participants and interactions involved with the export process.

· Export Application – serves as access point to export functionality.

· IxbHandlersManager – instantiates Export Handler for the object based on the object class and IX handlers registry. For each export session, there is only one instance of Export handler for all objects of the given class

· Exporter – invokes Export Handlers; serves as the context of export operation

· Export Handler - creates xml DOM document representing the object

The following figure shows the essential participants and interactions involved with the import process.

The following figure shows class hierarchy for IX handlers. Most of the existing IX handlers implement both ClassExporters and ElementImporters. However, this is not required.

Customization

Windchill IXB functionality can be customized in three different ways.

• Another export/import application, based on the IXB API can be developed. Corresponding APIs are defined in package wt.ixb.publicforapps.
• Existing export/import functionality can be extended: export/import for additional types of objects can be supported by supplying additional IXB plugable components (IX handlers) Corresponding APIs are defined in package wt.ixb.publicforhandlers.
• Object collection for export can be extended by supplying additional navigator components. Corresponding APIs are defined in package wt.ixb.objectset

Subpackages

wt.ixb.actor –contains actor classes which support ‘import as’ and restore use cases. In terms of java patterns, actors are decorators for IX class handlers

wt.ixb.applications - contains templates for export and import applications

wt.ixb.archive – contains helper classes for archive and restore specific functionality

wt.ixb.clientAccess – contains classes for client-server communication, including service classes and some utilities which assist in creating/reading data file and sending result to/from client

wt.ixb.conflictframework – contains classes related to conflict reporting and resolution

wt.ixb.epm – contains IX handlers and helper classes for CAD (EPM) objects

wt.ixb.handlers.forclasses – contains IX class handlers for ‘core’ objects

wt.ixb.handlers.forattributes – contains IX attribute handlers

wt.ixb.handlers.netmarkets – contains Netmarkets handlers and utility classes, which are used by container templates and PJL import/export

wt.ixb.impl – contains wrapper classes for xml DOM documents/elements and DTD manager.

wt.ixb.mapping - contains classes to support ufid mapping. Ixb uses ufid mapping to allow import of the same foreign object into different namespaces on the target system. Can be eliminated if standard ufid package becomes container aware

wt.ixb.objectset – contains classes which support collecting objects for export. Object collection is customizable, i.e. you can add custom navigators.

wt.ixb.pdx - contains classes for export in PDX format (the code was not released so currently is not supported)

wt.ixb.publicforapps - provides APIs to develop IXB application

wt.ixb.publicforhandlers - provides APIs to develop IXB plugable components.

wt.ixb.tuner – contains classes which support ‘tuning’ xml files prior to import with the mapping files. Tuning can be done with XSL or with xml ‘mapping’ files of special format. Examples of mapping files can be found in ..\codebase\registry\ixb\samples.

wt.ixb.util – contains various utility classes
