The CharacterDataAS Interface

• Extends the DOM2 Text interface (which itself extends the DOM2 CharacterData interface) with methods for guided document editing.

• IDL:

  interface CharacterDataAS : CharacterData {
    boolean isWhitespaceOnly();
    boolean canSetData(in unsigned long offset, in DOMString arg)
     raises(DOMException);
    boolean canAppendData(in DOMString arg) raises(DOMException);
    boolean canReplaceData(in unsigned long offset, 
     in unsigned long count, in DOMString arg)
     raises(DOMException);
    boolean canInsertData(in unsigned long offset, in DOMString arg)
     raises(DOMException);
    boolean canDeleteData(in unsigned long offset, in DOMString arg)
     raises(DOMException);
  };
  

• Java binding:

  package org.w3c.dom.abstractSchemas;
  
  public interface CharacterDataAS extends CharacterData {
  
    public boolean isWhitespaceOnly();
  
    public boolean canSetData(int offset, String arg)
     throws DOMException;
    public boolean canAppendData(String arg)
     throws DOMException;
    public boolean canReplaceData(int offset, int count, String arg)
     throws DOMException;
    public boolean canInsertData(int offset, String arg)
     throws DOMException;
    public boolean canDeleteData(int offset, String arg)
     throws DOMException;
  
  }
