Examples of PreflightPath

org.apache.pdfbox.preflight.PreflightPath
Contains a stack of objects to follow the validation path. Ex : - if the ValidationProcess computes a Type1Font object, this object should contains a path like PDPage|PDResources|PDFont. - if the ValidationProcess computes a XObject object, this object could contains a path like PDPage|PDResources|PDFontType3|PDResource|PDXObject.
