Class ParagraphRenderBox

public class ParagraphRenderBox extends BlockRenderBox

This articifial renderbox is the connection between block-contexts and the sequences of consectual inline-boxes of that block.

This renderbox generates lineboxes whenever needed.

When asked for layout-sizes or when doing the layouting, it first checks its validity and performs splits on all forced pagebreaks. At the end, there is no inner element's edge with an activated clear-property.

After that, it generates temporary lineboxes for all of its childs. When *re*-computing the layout, these lineboxes get invalidated and merged back into the paragraph.
