Class BoxBuilder

java.lang.Object

com.openhtmltopdf.layout.BoxBuilder

public class BoxBuilder
extends Object

This class is responsible for creating the box tree from the DOM. This is mostly just a one-to-one translation from the Element to an InlineBox or a BlockBox (or some subclass of BlockBox), but the tree is reorganized according to the CSS rules. This includes inserting anonymous block and inline boxes, anonymous table content, and :before and :after content. White space is also normalized at this point. Table columns and table column groups are added to the table which owns them, but are not created as regular boxes. Floated and absolutely positioned content is always treated as inline content for purposes of inserting anonymous block boxes and calculating the kind of content contained in a given block box.
