            }

           if(SysTreeNode::isApplObject(treeNode))

            }

            treeNode=iter.next();
        }
    }
  }

我收到错误消息内部运行堆栈溢出"，代码正确运行到第86次迭代，帮助...

I get the error "overflow in internal run stack",the code runs till 86th iteration correctly, help...

推荐答案

内核不会立即垃圾收集TreeNode对象.在为应用程序对象及其所有子对象完成一个树节点之后，您需要调用TreeNode.treeNodeRelease()，然后调用treeNode=null;以清理垃圾收集器.

The kernel doesn't immediately garbage collect TreeNode objects. Once you are done with a treenode for an application object and all it's children, you need to call TreeNode.treeNodeRelease(), followed by treeNode=null; to let the garbage collector clean up.

...
TreeNode treeNodeToRelease;
...

while(treenode)
{

    ... /* do stuff with treenode */

    if(treeNodeToRelease && SysTreeNode::isApplObject(treeNode))
    {
        treeNodeToRelease.treeNodeRelease();
        treeNodeToRelease=null;
    }
    if(SysTreeNode::isApplObject(treeNode))
    {
        treeNodeToRelease=treeNode;
    }
    treeNode=iter.next();
}
