Detailed Description

This class keeps track of information regarding link (destinations) that occur in the document.

This class keeps track of information regarding link (destinations) that occur in the document. Doing so enables us to drastically trim the amount of PdfDestinations that will end up being included in the document. For performance reasons it was decided to scan the DOM tree only once and store the result in a separate object (this object) in the ProcessorContext.

This class is not reusable and a new instance shall be created for every new conversion process.
