Method Summary |
boolean |
action()
Subclasses can make public if desired. |
boolean |
appearance(Context cx,
boolean all)
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. |
void |
destroy()
Removes span from document and its layer. |
void |
moveq(Leaf ln,
int lo,
Leaf rn,
int ro)
"move quick" just updates summaries, so more efficient than move(), if caller:
guarantees that first node comes before second node (so the system doesn't have to spend time checking this), and
handles all reformatting and repainting (including marking tree nodes dirty)
Useful using during initial tree builds, when adding spans and formatting in batch(es). |
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
moveq
public void moveq(Leaf ln,
int lo,
Leaf rn,
int ro)
- Description copied from class:
Span
- "move quick" just updates summaries, so more efficient than move(), if caller:
- guarantees that first node comes before second node (so the system doesn't have to spend time checking this), and
- handles all reformatting and repainting (including marking tree nodes dirty)
Useful using during initial tree builds, when adding spans and formatting in batch(es).
Checks that endpoint offsets are valid, that is, >=0 and
- Overrides:
moveq
in class Span
destroy
public void destroy()
- Description copied from class:
Span
- Removes span from document and its layer.
Different from moveq(null), which removes from document tree but not from layer.
If caller will handle all reformatting and repainting, as during a batch destory(), first moveq(null) on span.
- Overrides:
destroy
in class Span
action
public boolean action()
- Description copied from class:
ActionSpan
- Subclasses can make
public
if desired.
Maybe just send event instead.
- Specified by:
action
in class ActionSpan
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
