public class ColumnScanEmitter
Saxon extension to scan the column widths in a result tree fragment.
$Id: ColumnScanEmitter.java 5907 2006-04-27 08:26:47Z xmldoc $
Copyright (C) 2000 Norman Walsh.
This class provides a Saxon 6.* implementation to scan the column widths in a result tree fragment.
The general design is this: the stylesheets construct a result tree fragment for some colgroup environment. That result tree fragment is "replayed" through the ColumnScanEmitter; the ColumnScanEmitter watches the cols go by and extracts the column widths that it sees. These widths are then made available.
Change Log:
Initial release.
