Member Function Documentation

virtual void VOS_SavedData::DuplicatePagesHelperUsingStreamCopy ( PasteDataXRefContext *  xRefContext )

protectedvirtual

This method uses the StreamUtils::CreateDBStreamCopy() to duplicate the page.

Parameters

sourceStory
destStory

virtual void VOS_SavedData::DuplicatePagesHelperUsingTransferObject ( PasteDataXRefContext *  xRefContext )

protectedvirtual

This method creates an empty VOSDiskPage and then uses TranferObjectTo() to create new VOSObjects for the new VOSDiskPage the page.

Parameters

xRefContext

virtual void VOS_SavedData::PageTransferred ( IVOSDiskPage *  )

inlineprotectedvirtual

This method is called for each transfered Page from TransferPagesHelperNoTransferObject(), TransferPagesHelperUsingTransferObject(), DuplicatePagesHelperUsingStreamCopy(), and DuplicatePagesHelperUsingTransferObject() after processing is complete.

Parameters

page

virtual void VOS_SavedData::TransferPagesHelperNoTransferObject ( PasteDataXRefContext *  xRefContext )

protectedvirtual

This method will transfer VOSDiskPages by merely updating the Strand. The internal VOSObjects are not touched.

Parameters

xRefContent

virtual void VOS_SavedData::TransferPagesHelperUsingTransferObject ( PasteDataXRefContext *  xRefContext )

protectedvirtual

This method will transfer VOSDiskPages by calling TransferObjectTo() for each VOSObject.

Parameters

xRefContent
