          "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).

Method Detail

setInsertText

public void setInsertText(java.lang.String inserttxt)

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:
  1. guarantees that first node comes before second node (so the system doesn't have to spend time checking this), and
  2. 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

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 start)
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

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
