Examples of org.apache.pdfbox.util.PDFTextStripper$PositionWrapper

org.apache.pdfbox.util.PDFTextStripper
wrapper of TextPosition that adds flags to track status as linestart and paragraph start positions.
This is implemented as a wrapper since the TextPosition class doesn't provide complete access to its state fields to subclasses. Also, conceptually TextPosition is immutable while these flags need to be set post-creation so it makes sense to put these flags in this separate class.
