类名称：Flow
方法名：getExceptionHandlerSet

Flow.getExceptionHandlerSet介绍

[英]Returns the set of exception handlers, allowing manipulation of how exceptions are handled when thrown during flow execution. Exception handlers are invoked when an exception occurs at execution time and can execute custom exception handling logic as well as select an error view to display. Exception handlers attached at the flow level have an opportunity to handle exceptions that aren't handled at the state level.
[中]返回异常处理程序集，允许在流执行期间抛出异常时处理异常的方式。异常处理程序在执行时发生异常时调用，可以执行自定义异常处理逻辑，也可以选择要显示的错误视图。在流级别附加的异常处理程序有机会处理在状态级别未处理的异常。
