Examples of com.dbxml.db.core.data.Value

com.dbxml.db.core.data.Value
Value is the primary base class for all data storing objects. The content window of Value objects are immutable, but the underlying byte array is not.

      DocumentTable dt = DTSMHelper.textToTable(document, container.getCollection().getSymbols());
      container.setDocument(dt);
   }


   public void setValue(byte[] value) throws dbXMLException {
      container.setValue(new Value(value));
