本文介绍了Spark容器Halo的管理方法,包括子元素的添加、获取、删除和索引调整等操作,为开发者提供了详细的API使用指南。
  Spark容器 Halo容器 说明
  numElements numChildern 容器的子元素数量。
  addElement( ) addChild( ) 为容器添加自元素作为其最后一个子元素。
  addElementAt( ) addChildAt( ) 在容器的指定索引上添加子元素。
  getChildren( ) 得到所有包含的子元素的数组。
  getElementAt( ) getChildAt( ) 得到指定索引上的子元素。
  getChildByName( ) 得到带有指定id的子元素。
  getElementIndex( ) 得到子元素的索引。
  removeAllElements( ) removeAllChildren( ) 删除容器的所有子元素。
  removeElement( ) removeChild( ) 删除第一个子元素。
  removeElementAt( ) removeChildAt( ) 删除指定索引的子元素。
  setElementIndex( ) setChildIndex( ) 是这子元素的索引。
  swapElements( ) swapChildren( ) 交换两个子元素的索引。
  swapElementsAt( )
