Field Detail

### ATTR_ELIDE

    public static final java.lang.String ATTR_ELIDE

  Boolean flag, true=elide on.

    Constant Field Values

Constructor Detail

### ElideSpan

    public ElideSpan()

Method Detail

### setElide

    public void setElide(boolean elide)

### appearance

    public boolean appearance(Context cx,
                              boolean all)

  Description copied from interface: `ContextListener`
  Resets the graphics context every time the object is added to or dropped from the set active over the portion of the document being drawn. These behaviors can come from the style sheet, be ad hoc spans, be lenses, or come from elsewhere. Should be fast.

  Specified by:
    `appearance` in interface `ContextListener`
  Overrides:
    `appearance` in class `Span`
    `all` - all attributes or exclude those that are not inherited

### save

    public ESISNode save()

  Description copied from class: `Span`
  Stuff instance state into attributes; if save buffer not null, write out corresponding XML. Subclass should override if have interesting content (can stuff content into attr then super.save()). If span is not attached to tree at save time, its old attachment points are retained. This way, spans that can't be attached presently can be tried again without degradation.

  Overrides:
    `save` in class `Span`

### restore

    public void restore(ESISNode n,
                        java.util.Map<java.lang.String,java.lang.Object> attr,
                        Layer layer)

  Description copied from class: `Span`
  Given ESIS subtree, pluck class-specific information from attributes, call super.restore() for locations. Attributes named `start` and `end` are reserved to hold Robust Location data.

  Overrides:
    `restore` in class `Span`
  See Also:
    `RobustLocation`
