本文整理了Java中com.alibaba.citrus.util.Assert
类的一些代码示例,展示了Assert
类的具体用法。这些代码示例主要来源于Github
/Stackoverflow
/Maven
等平台,是从一些精选项目中提取出来的代码,具有较强的参考意义,能在一定程度帮忙到你。Assert
类的具体详情如下:
包路径:com.alibaba.citrus.util.Assert
类名称:Assert
[英]断言工具,用来实现Fail-Fast。
注意事项:
assertTrue(type instanceof MyType, "Unsupported type: " + type);
可以替换成:
assertTrue(type instanceof MyType, "Unsupported type: %s", type);
这样,当assertion顺利通过时,不会占用CPU时间。
此外,部分方法具有返回值,以方便编程,例如:
void foo(String param) {
bar(assertNotNull(param));
}
int bar(String param) {
if (true) {
...
}
return unreachableCode();
}
[中]断言工具,用来实现Fail-Fast。
注意事项:
*断言是用来明确设置程序中的条件和约定的,它是一种程序员之间交流的工具,而不是和最终用户交流的工具。
assertTrue(type instanceof MyType, "Unsupported type: " + type);
可以替换成:
assertTrue(type instanceof MyType, "Unsupported type: %s", type);
这样,当断言顺利通过时,不会占用中央处理器时间。
此外,部分方法具有返回值,以方便编程,例如:
void foo(String param) {
bar(assertNotNull(param));
}
int bar(String param) {
if (true) {
...
}
return unreachableCode();
