public abstract class Anno

extends Behavior

Superclass for PDF annotations. Provides methods for mapping PDF's geometric positions to structural, Individual annotations are implemented with separate behaviors (see subclass links), which generally convert PDF-specific annotation to format-independent Multivalent.

Method Detail

checkArgs

protected boolean checkArgs(java.lang.String subtype,
                            SemanticEvent se)

Returns true if semantic event is a PDF annotation, /Subtype matches subtype, and event's argument are valid.

createSpan

protected Span createSpan(SemanticEvent se,
                          java.lang.String logical,
                          java.lang.String bename)

Given /Rect (and handle to PDF) in semantic event, convert to Span.

decorate

protected void decorate()

Applies appearance properties common to all (most) annotation types.

semanticEventAfter

public boolean semanticEventAfter(SemanticEvent se,
                                  java.lang.String msg)

Description copied from class: Behavior

Round robin distribution to all behaviors. Message and clientData unpacked from SemanticEvent for convenience. Message is interned, so if you compare to a literal, you can use "==". Message can't be changed (it can be short-circuited out of), but client data can be mutated as it is passed along (so it's not passed as a parameter).
