Detailed Description

Export Handler interface, gets called for every element of the structure tree, when tree is iterated. this interface is on a service provider that provides service for kXMLExportHandlerSignalService. It gets asked whether or not it wants to export each element. It can respond yes (and will get called to handle) or no (and will not get called)

Member Function Documentation

virtual bool16 IXMLExportHandler::CanHandleElement ( IIDXMLElement *  element )

pure virtual

Called before element processed to determine whether this interface wants to handle it.

Parameters

element

specifies current node in structure tree during traversal

Returns

kTrue - Yes I will handle it : kFalse - No I will not

Implemented in DataUpdaterExportHandler.

virtual bool16 IXMLExportHandler::HandleAfterNthChild ( IXMLOutStream *  stream, IIDXMLElement *  element, int32  childIndex  )

pure virtual

Called after each child is processed. This is the place to do stuff in between child elements

Parameters

stream	specifies the stream out export the element to
element	specifies current node in structure tree during traversal
childIndex	index in parent of child

Returns

kTrue - I handled this element : kFalse - I did not handle this element

Implemented in DataUpdaterExportHandler.

virtual bool16 IXMLExportHandler::HandleElementAfter ( IXMLOutStream *  stream, IIDXMLElement *  element  )

pure virtual

Called after element processed. Use this to close the element after all of its children/content has been exported.

Parameters

stream	specifies the stream out export the element to
element	specifies current node in structure tree during traversal

Returns

kTrue - I handled this element : kFalse - I did not handle this element

Implemented in DataUpdaterExportHandler.

virtual bool16 IXMLExportHandler::HandleElementBefore ( IXMLOutStream *  stream, IIDXMLElement *  element  )

pure virtual

Called before element processed.

Parameters

stream	specifies the stream out export the element to
element	specifies current node in structure tree during traversal

Returns

kTrue - I handled this element : kFalse - I did not handle this element

Implemented in DataUpdaterExportHandler.
