本文整理了Java中org.hibernate.mapping.Index类的一些代码示例，展示了Index类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Index类的具体详情如下：
包路径：org.hibernate.mapping.Index
类名称：Index

  while ( iter.hasNext() ) {
    Index parentIndex = (Index) iter.next();
    Index index = new Index();
    index.setName( getName() + parentIndex.getName() );
    index.setTable( this );
    index.addColumns( parentIndex.getColumnIterator() );
    indexes.add( index );
  }
  return new JoinedIterator(
      indexes.iterator(),
      super.getIndexIterator()
  );
}
