public AbstractMixedInlinePL(org.axsl.fo.Fo realFObj,
                             PioneerLS layout)

Constructor.

Parameters:

realFObj - The FO Tree object which is being laid out.

layout - The ancestor layout system.

Method Detail

layout

public Status layout(org.axsl.area.AreaNode areaNode,
                     org.axsl.fo.fo.GraftingPoint graftingPoint)
              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.

makeNormalInlineArea

protected abstract org.axsl.area.AncestralNormalInlineArea makeNormalInlineArea(org.axsl.area.LineContentFactory lineContentFactory,
                                                                                org.axsl.fo.fo.GraftingPoint graftingPoint)

Creates the subclass-specific area into which the child objects will be laid out.

Parameters:

lineContentFactory - The line content factory that should be used to create the new area.

graftingPoint - The grafting point, if any, which controls the new area.

Returns:

The newly-created area.
