Constructor Detail

### MainReference

    public MainReference(BodyRegion parent)

  Constructor

  Parameters:
    `parent` - the body region this reference area is placed in.

Method Detail

### createSpan

    public Span createSpan(boolean spanAll)

  Add a span area to this area.

  Parameters:
    `spanAll` - whether to make a single-column span
  Returns:
    the created span area.

### getSpans

    public java.util.List getSpans()

  Get the span areas from this area.

  Returns:
    the list of span areas

### setSpans

    public void setSpans(java.util.List<Span> spans)

  Do not use. Used to handle special page-master for last page: transfer the content that had already been added to a normal page to this main reference for the last page. TODO this is hacky.

  Parameters:
    `spans` - content already laid out

### getCurrentSpan

    public Span getCurrentSpan()

  Get the span area currently being filled (i.e., the last span created).

  Returns:
    the active span.

### isEmpty

    public boolean isEmpty()

  Indicates whether any child areas have been added to this reference area. This is achieved by looping through each span.

  Returns:
    true if no child areas have been added yet.

### getColumnCount

    public int getColumnCount()

  Returns:
    the number of columns

### getColumnGap

    public int getColumnGap()

  Returns:
    the column gap in millipoints

### setWritingModeTraits

    public void setWritingModeTraits(WritingModeTraitsGetter wmtg)

  Sets the writing mode traits for the spans of this main reference area.

  Overrides:
    `setWritingModeTraits` in class `Area`
  Parameters:
    `wmtg` - a WM traits getter
