              throws org.axsl.area.AreaTreeException

Description copied from class: FONodePL

Each FONodePL subclass implements this method on a manner appropriate for its content.

Specified by:

layout in class FONodePL

Parameters:

areaNode - The Area in which the contents to be laid out by this should be placed. For example, for TableCellPL layout method, area should be a TableRowContainer. During the layout process, at least one TableCellArea should be created, which is then passed to layout for the children of the TableCell now being laid out.

graftingPoint - The RetrieveMarker instance, if any, into which this content will be laid out.

Returns:

An integer representing the status of this layout. When laying out FOText, this marks the index to the last character that was successfully laid out plus one, that is, it marks the next character to be laid out. For FObj subclasses, this indicates the index to the last child that was successfully laid out plus one, that is, it marks the next child that should be laid out.

Throws:

org.axsl.area.AreaTreeException - For errors during layout.
