stringbuffer

Consider for example usage of the thread safe StringBuffer .

举例来说，考虑一下线程安全的StringBuffer的用法。

Public synchronized StringBuffer insert ( int offset , String str );

用来在字符串的索引offset位置处插入字符串str。

However , there is a performance penalty here , since a StringBuffer must work to transparently increase its size and shift the data around .

不过此处有性能损失，因为StringBuffer必须透明地增加其大小和对数据移位。

In this case , the StringBuffer has non-local scope and can be accessed by several threads .

在这个例子中，StringBuffer的作用域是非局部的，可以被多个线程访问。

Changing it to StringBuffer , however , will not be flagged as problem , because it does have a length () method .

然而如果将其变成StringBuffer，问题就不会标记出来，因为StringBuffer的确具有方法length（）。

This section explains how to integrate ropes into a Java application and compares rope performance with that of String and StringBuffer .

这一节将解释如何将rope集成进Java应用程序，并比较rope与String和StringBuffer的性能。

The familiar advice is ; use StringBuffer instead of a String if you are going to be mutating it .

一个类似的建议是，如果你希望字符串是可变的，就应该使用StringBuffer。

String is immutable and if we are doing work that requires mutations , StringBuffer is a less costly alternative .

String是不可变的，但如果我们的工作需要字符串有很多变化，StringBuffer将是一个开销较低的选择。

If the binding corresponds to a variable , it creates a StringBuffer containing the variable 's name , a colon , and its type .

如果该绑定和变量相对应，贡献器会创建一个包含该变量名、冒号和其类型的StringBuffer。

You can sometimes further improve performance by setting the initial capacity of a StringBuffer ; the class is designed to automatically grow when it can no longer hold all its data .

有时可以通过设置StringBuffer的初始容量进一步提高性能；该类的设计使其可以在不能保存全部数据时自动扩大容量。

The IBuffer interface is similar to StringBuffer , the principal difference being that changing the buffer associated with a compilation unit updates the corresponding elements of the Java model .

IBuffer接口类似于StringBuffer，其原理不同之处在于，更改与编译单元相关的缓冲区更新了Java模型的对应元素。

Given the single threaded nature of this benchmark , I was fully expecting Escape Analysis to elide the lock thus rendering StringBuffer performance equivalent to that of StringBuilder .

明确了这个基准测试的单线程化的本质后，我期待着逸出分析会消除锁，从而将StringBuffer的性能提到了与StringBuilder相同的水平。

If the IBinding is an IFunction , the contributor forms a StringBuffer containing the function 's name and parameters & separated by commas and surrounded by parentheses .

如果IBinding是一个IFunction，贡献器会构造一个包含该函数名和参数（由逗号隔离并用圆括号括住）的StringBuffer。
