我写了一个应用程序，但由于某种原因，它一直保持在 100% 的峰值。我在一些类上运行了配置文件 r，并且报告显示 isReset() 和 isRunning() 似乎被调用了很多次。你看有什么不对的，请告诉我。谢谢
1 类是唯一使用 isReset() 代码的类，所以我希望这有助于你们检测错误

*/
// Additions:
/* ver 0.25 August 2004
* Added recursion in SkaExecutionPanel by adding SkaFunction
* and using desktop internal panes.
*
* Added binary tree node annotation - text and drawn
* Added subtree highlight feature to VizBinaryTreeNode using SkaRectangle
* Improved node highlighting and selection scheme in VizBinaryTrees/VizDS
* Added Binary tree save and read methods
* Added visual subtree deletion (has bug)
*
* Added ability to set breaks from within algorithm

* Added Font Adjustment and Color scheme options to show on overhead projectors
*
* Found bug in SkaGraph deleteVertex (with edges)
*/
/* ver 0.16 October 15, 2001
Added Graph save and read methods.
Save is an instance method, while read is a class method.
Added circular layout for graphs,
Added fit/adjust graph layout to plate size method.
Added label editing for Binary Trees and Graphs.
SkaLabels (glyphs) now truncate the string displayed to the width specified
in the constructor.
*/
/* ver 0.15 July 21, 2001
Fixed Reset function in Execution using exceptions so that Ska Algorithms
can be run repeatedly without quitting the entire Ska System.
This also allows trying the same program on different data structures.
Problems with reset so far:
1. Reset message to user can appear much later.
I think this is an I/O sequencing problem and it should go away if
a message status GUI area is used.
2. Bound variable names remain afterwards,
e.g. Graph bound to G will still show name as G after
algorithm is interrupted.
Fixed problem with multiple input requests in 0.14 - by adding another
wait call which waits on before asking for input.
Also introduced trial orderly layout of canvas and program windows ,
which fixes problem in 0.14
*/
/* ver 0.14 July 18, 2001
Added subclasses of SkaProgram, so that multiple programs
can run simultaneously.
Problem - when multiple programs start, their windows overlay each other
Problem - Send DS to algorithm can get confused, if an algorithm
requests input while another is waiting on input or if
two algorithms request input at the same time
*/
/* ver 0.13
Added BinaryTree - does not have node value display yet.
Added arrows on edges of directed graphs
*/
/* ver 0.12
Added VizElementListener - separated from VizElement
Element Input menu item only highlights when input for that DS is requested
DS Input has been cleaned up
*/
/* ver 0.11
can ask user to select individual elements, e.g. vertices
removed standard java cloning code which wasn't being used anyway
