exceptions会导致control flow的突变,典型的就是将控制从当前运行的程序或任务转移到exception handler的执行(详见1.1节)。在计算机程序中,我们设计了jump和branch,call和return;他们通过program state的变化,引起了control flow的突变。exceptions中的control flow的突变是通

Exceptional Control Flow(2) Faults Faults result from error conditions that a handler might be able to correct. When a fault occurs, the processor transfers control to the fault handler. If the handler is able to correct the error condition, it returns control to the faulting instruction, ...
It is a often used principle in FP to use exceptions for control flow. These exceptions can hold complex values that should not be stringified (they might have recursive values loops) Or I noticed that's exactly what js.HaxeError does... it Std.string the exception value when the exceptio...

Performance Sin - Using Exceptions To Control Flow發行項 2008/02/02 Want to spot coding anti-patterns from performance perspective without actually looking in the code? One of the common performance coding anti-patterns I’ve noticed lately is using Exception Handling to control program flow. The...
The code which is prone to exceptions is placed in the try block. When an exception occurs, that exception occurred is handled by catch block associated with it. Every try block should be immediately followed either by a catch block or finally block. A catch statement involves declaring the ...
A high rate of .NET Framework exception handlers were called in the profiling data. Consider using other control flow logic to reduce the number of exceptions that are thrown. Rule Description While the use of exception handlers to catch errors and other events that disrupt program execution is ...
8.1 exceptions Exceptions are a form of excepional control flow that are implemented partly by the hardware and partly by the operating system. A state is encoded in various bits and signals inside the processor. The change in state is known as an 'event'. ...
