Method Detail

setPoints

public void setPoints(int points)

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

semanticEventBefore

public boolean semanticEventBefore(SemanticEvent se,
                                   java.lang.String msg)
Description copied from class: Span
Morphing and deletion menu items in popup.

Overrides:
semanticEventBefore in class Span

semanticEventAfter

public boolean semanticEventAfter(SemanticEvent se,
                                  java.lang.String msg)
Description copied from class: Span
Recognize "deleteSpan " and "morphSpan ".

Overrides:
semanticEventAfter in class Span

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
