Groovy In Action 笔记 (4) -- String相关 String类型作为使用频率最高类,大部分语言对此类型做了特殊的优化,如Java中的String Pool, 用来避免不停地在堆中实例化相同的字符串,从而提高效率。 下面介绍一下Groovy中的String类型的一些操作,代码如下: //Strings//literal stringdef words = "Hello"assertwords.clas...
voidwrite(String message){ message="prefix---:"+message defclazz = this.getClass() //遍历mixin的链表,找到当前mixin的前一个 for(mixininmixedIn.mixinClasses){ if(mixin.mixinClass.theClass==metaClass.delegate.theClass)break clazz=mixin.mixinClass.theClass } mixedIn[clazz].write(message) } }...
In Groovy, enclosing text with double quotes signifies the creation of a GString, which can be either interpolated or left as a regular Java String. The same behavior applies to the multi-line String variants. Utilizing triple single and quotes creates results in an unchangeable multi-line Strin...

5.in操作符 表示contains或isCase 6.相等比较 == 不同于java,groovy中==表示对象的比较,调用的是equals方法,要表示引用的比较的话,应该用is或者对象的is方法来表示 7.强转操作符 as 如果两个类型之间没有继承关系,直接用括号()强转是会抛类型转换异常的,但如果用as来替代就可以,比如 String a = (123 as...
