Method Detail

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

paintBefore

public boolean paintBefore(Context cx,
                           Node node)
Description copied from class: Behavior
A tree walk protocol, called before observed node has been painted. Called in same coordinate space as node's painting. Can be used draw special background, but usual background setting is done by spans or style sheets.

Overrides:
paintBefore in class Behavior
Returns:
true to short-circuit to paintAfter at that node, bypassing painting of the subtree.

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

semanticEventBefore

public boolean semanticEventBefore(SemanticEvent se,
                                   java.lang.String msg)
Navigate to referring links in same document, in span's popup menu.

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
