Method Summary |
boolean |
appearance(Context cx,
boolean all)

the set active over the portion of the document being drawn. |
void |
restore(ESISNode n,
java.util.Map<java.lang.String,java.lang.Object> attr,
Layer layer)
Given ESIS subtree, pluck class-specific information from attributes, call super.restore() for locations. |
ESISNode |
save()
Stuff instance state into attributes; if save buffer not null, write out corresponding XML. |

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
