stack与heap、new的内存分配、static对象。(effective c++ 04)

阅读effective c++ 04 (30页) 提到的static对象和堆与栈对象."不同编译单元内定义的non-local static对象". 了解一下. 目录 stack与heap 1.Stack 2.Heap 或謂 system heap 3.例子 1.构造函数型 (stack) 2.new型 (heap 動態分配) 4.构造函数型 (stack) 1.stack objects 的生命期 2.static local objects 的生命期 3.global obj

Java 堆内存与栈内存异同(Java Heap Memory vs Stack Memory Difference)

--reference Java Heap Memory vs Stack Memory Difference 在数据结构中,堆和栈可以说是两种最基础的数据结构,而Java中的栈内存空间和堆内存空间有什么异同,以及和数据结构中的堆栈有何关系? 一.Java 堆存储空间堆内存(堆存储空间)会在Java运行时分配给对象(Object)或者JRE的类.只要我们创建了一个对象,那么在堆中肯定会分配一块存储空间给这个对象.而我们熟知的Java垃圾回收就是在堆存储空间上进行的,用以释放那些没有任何引用指向

gcc内嵌汇编简介在内嵌汇编中,可以将C语言表达式指定为汇编指令的操作数,而且不用去管如何将C语言表达式的值读入哪个寄存器,以及如何将计算结果写回C 变量,你只要告诉程序中C语言表达式与汇编指令操作数之间的对应关系即可, GCC会自动插入代码完成必要的操作. 1.简单的内嵌汇编例: __asm__ __volatile__("hlt"); "__asm__"表示后面的代码为内嵌汇编,"asm"是"__asm__"的别名.&

hotspot的Heap Memory和Native Memory

JVM管理的内存可以总体划分为两部分:Heap Memory和Native Memory.前者供Java应用程序使用的:后者也称为C-Heap,是供JVM自身进程使用的.Native Memory没有相应的参数来控制大小,其大小依赖于操作系统进程的最大值,以及生成的Java字节码大小.创建的线程数量.维持java对象的状态信息大小(用于GC)以及一些第三方的包,比如JDBC驱动使用的native内存. Native Memory里存些什么?(1)管理java heap的状态数据(用于GC);(2

JVM Heap Memory和Native Memory

JVM管理的内存可以总体划分为两部分:Heap Memory和Native Memory.前者我们比较熟悉,是供Java应用程序使用的:后者也称为C-Heap,是供JVM自身进程使用的.Heap Memory及其内部各组成的大小可以通过JVM的一系列命令行参数来控制,在此不赘述.Native Memory没有相应的参数来控制大小,其大小依赖于操作系统进程的最大值(对于32位系统就是3~4G,各种系统的实现并不一样),以及生成的Java字节码大小.创建的线程数量.维持java对象的状态信息大小(用
