With a JIT compiler, Java programs are compiled one method at a time as they execute into the native processor's instructions to achieve higher performance. 使用JIT编译器时,Java程序按每次编译一个方法的形式进行编译,因为它们在本地处理器指令中执行以获得更高的性能。
Then, if you try to add a JLabel to that collection, the compiler picks up the discrepancy and complains at compile time. 然后,如果想要将JLabel添加到集合,则编译器会在编译时发现差异和并抛出异常。
Because of its static nature, precompiled code unlike code generated dynamically by a JIT compiler can't benefit from further optimisations of frequently used methods over time. 预先编译的代码有着静态的本质&与JIT编译器动态生成的代码不同,因而不可能在经过一段时间后,得益于常用方法的进一步优化。
The style sheet compiler therefore constructs a decision tree which is used at run time to decide which template rule to apply to a given node. 因此样式表编译器构造了决策树,在运行时用它来决定将哪个模板规则应用于给定节点。
In an RT environment, however, the JIT compiler introduces an unpredictable run-time behaviour that wreaks havoc on worst-case execution time analysis. 然而,在RT环境中,JIT编译器引入了不可预知的运行时行为,这将严重影响最坏情况时执行时间分析。
The dynamic JIT compiler that WebSphere Real Time uses has been specially adapted for use in RT systems. WebSphereRealTime使用的动态JIT编译器针对在RT系统中的使用进行了专门的调整。
A typesafe query API must enable your code to refer to the persistent attribute named age in a Person class in a way that a compiler can verify at compile time. 类型安全查询API必须让您的代码能够引用Person类中的持久化属性age,同时让编译器能够在编译期间检查错误。
Several of the Java runtime systems particularly the JIT compiler and classloaders initialise over time, which can consume native memory. 一些Java运行时系统特别是JIT编译器和类加载程序的初始化过程需要一段时间,这也会消耗本机内存。
In fact, I could argue that I would have finished writing a buggy, yet not-well-tested version of the DFA compiler this month if I hadn't spent so much time on automated tests. 事实上,如果不是在自动化测试方面花了大量的时间,我可能认为在这个月本可以编写完一个还有一些错误且没有经过良好测试的DFA编译器的版本。
This marker is enforced strongly by the compiler and weakly at run time; that is, the runtime will expose the internals via reflection if asked. 该标记由编译器强制执行,在运行时则不能很好地被执行;即,运行时将通过映像(reflection)公开这些内部内容(如果要求的话)。
The compiler simply assumes that the value of num_proc2 will be equal to1 every time, and generates the code for that branch by default. 编译器简单地假设在任何时候numproc2都等于1,并且默认地为该转移生成代码。
To get some insight into what the compiler is doing, try invoking the JVM with the-XX:+ PrintCompilation flag, which causes the compiler ( client or server) to print a short message every time it runs. 为了深入了解编译器做了什么,请用-XX:+PrintCompilation标志调用JVM,这个标志会使编译器(客户机或服务器)每次运行的时候打印一条短消息。
Jikes is an excellent Java compiler from IBM that greatly improves your build time. Jikes是IBM的一种出色的Java编译器,它极大地改善了您的构建时间。
However, the JIT compiler must also carefully balance the time it takes to compile a program because that time adds to the program's execution time. 然而,JIT编译器还必须注意抵消它编译程序消耗的时间,因为这些时间将延长程序的执行时间。
This will allow you to compile Flex source code without having to specify the location of the Flex compiler each and every time. 这将允许您编译Flex源代码,并且不需要每次都指定Flex编译器的位置。
The JIT compiler is selective about which code it compiles so that the time it takes to do the compilation is likely to be made up by the improvements to the code's performance. JIT编译器将选择它要编译的代码,这样它花费的编译时间很可能通过对代码性能的改进得到补偿。
With a static compiler that only compiled one class at a time, we'd be out of luck. 对于每次只编译一个类的静态编译器,我们很幸运。
With '-O', the compiler tries to reduce code size and execution time, without performing any optimizations that take a great deal of compilation time. 加上-O选项,编译器会尽可能的缩短代码长度和运行时间,不会执行一切耗费大量时间的优化行为。
New Term: The preprocessor runs before your compiler each time the compiler is invoked. 新术语:每次调用编译器时,预处理器都会在编译器之前运行。
With generic types, the compiler can catch type mismatches before run time. 利用泛型类型,编译器可以在运行时之前捕获类型不匹配错误。
The compiler is internally multithreaded resulting in faster build time depending on the platform used for compilation. 这个编译器内部支持多线程,这样就能够在基于编译所用的平台上获得更快的构建时间(BuildTime)。
Sunday Times Rich List compiler Philip Beresford said this would be the first time a British lottery winner had appeared in the list. 据《星期日泰晤士报》富翁榜编撰人菲利普•贝雷斯福德介绍,这是英国彩票中奖者首次跻身该榜。
The compiler provides a built-in function, which is evaluated at compile time, to determine the length of an array ( e.g.len ( a)). 编译器提供了内建的功能在编译时求得一个数组的长度(如len(a))。
The compiler alters the function name each time it appears in your program, and the linker matches them up appropriately. 每次函数名出现在程序中的时候编译器就替换它,然后连接器正确的把它们匹配起来。
A binary output program of the compiler that is optional at compile time. 编译程序输出的一种二进制目标输出程序,在编译时可以进行选择是否输出这种表。
When a virtual function is called through a reference or pointer, the compiler generates code to decide at run time which function to call. 当虚函数通过引用或者指针调用时,编译器生成代码来决定在运行期调用哪个函数。
Every one of the@ AspectJ examples we've seen can be compiled using the AspectJ compiler or applied using AspectJ load time weaving, as well as being applied by Spring. 我们看到的每一个@AspectJ例子都能使用AspectJ编译器编译,或者使用AspectJ加载时织入来使用,也能被Spring应用。
This assumption, though safe for various static analyses for compiler optimizations, could spell doom for an anti-virus technology by increasing the time and space costs of the analyses. 这个假定,虽然对编译器最优化使用的各种静态分析来说是安全的,但是由于增加了时间和空间的代价,会致反病毒技术于不利处境。
( b) The style of DU's poems differed from the opinions of the compiler and from the major opinions of poetry aesthetic at that time. 杜诗风格与编选者的主张及当时诗歌审美的主流相悖。
Compiler developers can focus on these hot paths to save their time. 编译器开发人员可以专注精力分析热路径上的代码,大大节省了工作量。
