Class DrawingPropsIdTracker

java.lang.Object
org.docx4j.openpackaging.parts.WordprocessingML.DrawingPropsIdTracker
public class DrawingPropsIdTracker extends Object
wp:docPr/@id must be unique across all parts in a docx, otherwise Word can't open the docx. This problem is difficult to track down if you aren't aware of it, so this class attempts to keep track of Ids in use, and dispense unique values. There is one DocPropIdTracker per package. Relies on Docx4jUnmarshallerListener so is susceptible to those cases where that listener is not listening.
