XML files that contain handlers information
These XML files reside in the folder <Windchill>\codebase\registry\ixb\handlers. The whole folder is processed as the root element of XML tags, and the contents of XML files in this folder are processed as child elements. So, the XML files in this folder are not well formed, and they have contents similar to the following:
<classExporter>
<class>
[class name of the object that will be exported with full path name]
</class>
<dtd>
[String DTD, specifies where DTD for the class is stored]
</dtd>
<targetTag>default</targetTag>
<handler>
[class name of the handler that is used to export the object]
</handler>
</classExporter>
For example:
<classExporter>
<class>wt.part.WTPart</class>
<dtd>standardX20.dtd</dtd>
<targetTag>default</targetTag>
<handler>wt.ixb.handlers.forclasses.ExpImpForWTPart</handler>
</classExporter>
All handlers with the <dtd> tag “standard.dtd” are handlers for export object in Windchill Release 10.X.
For example:
<classExporter>
<class>wt.part.WTPart</class>
<dtd>standardX20.dtd</dtd>
<targetTag>default<targetTag>
<handler>wt.ixb.handlers.forclasses.ExpImpForWTPart60</handler>
</classExporter>
So we know that the class wt.ixb.handlers.forclasses.ExpImpForWTPart is a handler for exporting the class wt.part.WTPart in Windchill Release 10.X format.
The class IxbHandlersManager contains all necessary methods to manipulate handlers.
