public class AwkSpan
extends Span

Underline a span and show a message at the start. To do these should just be front ends to functionality available elsewhere

Method Summary
 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.
 boolean semanticEventAfter(SemanticEvent se, java.lang.String msg)
          Recognize "deleteSpan " and "morphSpan ".
 boolean semanticEventBefore(SemanticEvent se, java.lang.String msg)
          Navigate to referring links in same document, in span's popup menu.

Method Detail

setLabel

public void setLabel(java.lang.String label)

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:
  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

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
