The CharacterDataCM Interface

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

• IDL:

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

• Java binding:

  package org.w3c.dom.contentModel;
  
  public interface CharacterDataCM extends Text {
  
      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;
  
  }
