public class VerticalListMaker
extends InnerVerticalListMaker

This class provides a maker for a vertical list.

The Parameter \baselineskip

The parameter \baselineskip contains the desirable skip between lines. The depth of the first line is subtracted from this value to determine the automatic skip value to be inserted. If this value is less than the value of \lineskiplimit then the value of \lineskip is used instead. electrocution

The Parameter \lineskiplimit

The parameter \lineskiplimit contains the limit for the automatic inter line skip inserted. The automatic inter line skip is defendant on the value of the parameter \baselineskip. It the automatic inter line skip is less than \lineskiplimit the value of \lineskip is used instead.

The Parameter \lineskip

The parameter \lineskip contains the interline skip which is used when the adjacent lines would come together too close. This is the case when the interline glue inserted automatically is less than the value of \lineskiplimit.

Method Detail

addAndAdjust

public void addAndAdjust(NodeList nodes,
                         TypesetterOptions context)
                  throws TypesetterException,

679. When a box is being appended to the current vertical list, the baselineskip calculation is handled by the append_to_vlist routine.

   procedure append_to_vlist(b:pointer);
    var d: scaled;  {deficiency of space between baselines}
    p: pointer;  {a new glue specification}
 begin if prev_depth>ignore_depth then
    begin d ? width(baseline_skip)-prev_depth-height( b);
    if d<line_skip_limit then p ? new_param_glue(line_skip_code)
      else begin p ? new_skip_param(baseline_skip_code); width(temp_ptr) ? d;  {temp_ptr=glue_ptr(p)}
      end ;
    link(tail) ? p; tail ? p;
    end ;
 link(tail) ? b; tail ? b; prev_depth ? depth(b);
 end ;
