调用栈

调用栈将异常传递给catch（）块，异常正是通过这种方式被返回给用户的。

The call stack passes the exception to the catch () block , and that is how it gets returned to the user .

始终在调用栈的最高层（API层）启动事务有时会效率低下，特别是对于具有高用户吞吐量和高数据库并发性需求的应用程序。

Always starting transactions at the highest level in the call stack ( the API layer ) can be inefficient , particularly in cases of high-user-throughput and high-database-concurrency needs .

如果不使用引用，就需要将整个数组或hash表复制到该函数的调用栈中，然后在函数中再次对其进行复制。

Without a reference , you copy the entire array or hash onto the function call stack , and then copy it again in the function .

Debug视图（不要与Debug透视图混淆）展示了调用栈（callstack），Variables视图展示了程序变量的当前状态，而Console视图则展示了程序。

The Debug view ( not to be confused with the Debug perspective ) shows the call stack , the Variables view shows the current state of the program 's variables , and the Console view shows the program .

您是否了解应如何有效利用Rubinius清晰可见的内部结构，例如可以在运行时刻访问并修改字节码、查看调用栈？

Do you have ideas what you could do with Rubinius'transparency and accessible internals , i.e.accessing and modifying bytecode at runtime , inspecting the call stack etc. ?

名为Cylon的调试器提供了人们所能想到的所有特性：传统的断点、基于异常的断点、调用栈、监视器以及变量的查看和操作。

The debugger – called Cylon – provides all the features one could expect : conditional breakpoints , breakpoints on exceptions , call stack , watches , the exploration and manipulation of variables .

backtrace（frameCount）&将当前调用栈的快照复制到一个LzBacktrace对象中，之后便可以打印或查看该对象。

Backtrace ( frameCount ) & Copy the snapshot of the current call stack into a LzBacktrace object , which can then be printed or inspected .

调用栈的检查在遇到PrivilegedAction实例时停止，有效地将执行指定操作所必需的许可权授予所有的后继类调用。

The check of the calling stack stops when it encounters a PrivilegedAction instance , effectively granting all subsequent class calls the required permission to perform the specified operation .

“变量”面板、“调用栈”面板和“观察”面板。

Variables panel , call stack panel , watch panel .

显示程序和函数的当前调用栈。

Display the current call stack of programs and functions .

要使操作成功完成，调用栈中的每个类必须有必需的许可权。

Each class in the calling stack must have the required permissions for the operations to complete successfully .

您可以选择调用栈中的条目，这样可以显示变量被调用时的值。

Entries on the call stack can be selected , causing variables at the time of invocation to be displayed .

每当实际代码碰到任何类型的错误，它就抛出一个异常，然后该异常就进入调用栈。

Whenever the actual code encounters any type of error , it throws an exception , which then goes to the call stack .

不用在相同的方法中使用编程事务，而是将更新操作移动到调用栈的另一个公共方法中。

Rather than using programmatic transactions within the same method , you can move the update operations to another public method within the call stack .

实际上，尾递归消除了对递归使用调用栈的需要；因此，可以实现任意深度的递归并且可以避免栈溢出。

Essentially , tail recursion eliminates the use of the call stack for recursion ; thus , arbitrarily deep recursion is possible and avoids stack overflow .

这对调试器来说是难以置信地有用-它意味着调用栈完全可靠，即使你没有正被调试的所有模块的符号。

This was unbelievably useful for debuggers-it meant that call stacks were quite reliable , even if you didn 't have symbols for all the modules being debugged .

对于“Lock[AQS@135]”，它在一个程序位置出现竞争，显示了竞争的次数，时间和竞争时刻的线程调用栈。

For " Lock [ AQS @ 135 ] ", it contends in one place , showing contention count , contention time , and full stack back trace of the contention .

通过此技巧，您可以有效地在调用栈的较低层次开始事务，从而减少花费在数据库中的时间。

With this technique , you are effectively starting the transaction at a lower level in the call stack , thereby reducing the amount of time you are in the database .

但是，即使是不可取消的任务也应该尝试保留中断状态，以防在不可取消的任务结束之后，调用栈上更高层的代码需要对中断进行处理。

However , even noncancelable tasks should attempt to preserve the interrupted status in case code higher up on the call stack wants to act on the interruption after the noncancelable task completes .

并用虚拟机维护由代码区、数据区、函数调用栈、操作数栈和指令计数器等共同构成的运行时环境，控制程序的执行，有利于实现调试功能。

The virtual machine maintains the run-time environment , which is composed of code section , data section , function calling stack , operand stack , instruction pointer , etc. All that is good to the executing and the debugging of program .

能耗模拟器设计采用基于任务的能耗分析策略，通过利用任务能耗表和函数调用能耗栈机制解决在操作系统环境下能耗模拟遇到的能耗混杂难题，能够准确地模拟每个并发运行程序的能量消耗。

Task based strategy to analyze energy consumption was adopted . A mechanism that use task energy sheet and function energy stack was employed to solve mixing of energy consumption that occurs during simulating energy consumption in OS environment and can accurately simulate energy consumption form every concurrent program .

每个线程一个栈，每个方法调用一个栈帧。

A stack frame contains the state of one Java method invocation .

在尾部调用之后除去栈结构的方法称为尾部调用优化。

The idea of removing stack frames after tail-calls is called tail-call optimization .

方法调用一直沿着栈传递调用，可能传递到最终目标，或到下一个截取程序。

The method call passes the invocation up the stack , either to the final target or possibly to the next interceptor .

这就使得Emacs可以显示更多的信息，包括调用堆栈、当前栈的局部变量以及各断点的状态。

This allowed Emacs to display more information , including the call stack , local variables of the current stack and the status of any breakpoints .

好像一旦控制权传递给了尾部调用的函数，栈中就再也没有有用的内容了。

It seems that once control is passed to the tail-called function , nothing in the stack is useful anymore .

通过这种方式，如果一个设计调用一个主机栈，您可以替换一个协调的虚拟机系统。

In this way , if a design calls for a hosting stack , you can substitute a compatible virtual system .
