public String toString() {return "a server"} } 推荐使用如下简洁的写法 class Server { String toString() {"a server"} } 你可能会关心包范围内的可访问性问题。事实上,Groovy允许省略public, 是因为这个包范围里面默认情况下是不支持public,但是事实上有另外一个Groovy注释语法去实现可访问性: class Server...
{ String firstName String lastName } def p1 = new Person(firstName: 'Jack', lastName: 'Nicholson') def p2 = new Person('Jack') try { // will fail because the second property is not included def p3 = new Person('Jack', 'Nicholson') } catch (e) { assert e.message.contains ('...
def String name = "Guillaume" 这样写就足够了: String name = "Guillaume" 在Groovy 中使用 def 时,实际的类型持有者是 Object,所以可以将任何对象赋予利用 def 定义的变量,如果一个方法声明为返回 def 类型值,则它会返回任何类型的对象。 定义带有无类型参数的方法时,可以使用 def,但并不是必需条件,因此...

def String name = "Guillaume" 1. 而是这样: AI检测代码解析 String name = "Guillaume" 1. 当在Groovy中使用def,对象实际的类型是Object(所以使用def定义的变量可以分配任何类型的对象,同时如果一个方法声明返回def则可以返回任何类型的对象)。 当使用无类型参数定义一个方法,你可以使用def关键字,但是不是必须的...
assert ['a','b','c'].contains('a') // equivalent to the `contains` method in Java<br /> assert [1,3,4].containsAll([1,4]) // `containsAll` will check that all elements are found<br /> assert [1,2,3,3,3,3,4,5].count(3) == 4 // count the number of elements which...
If your command chain contains an odd number of elements, the chain will be composed of method / arguments, and will finish by a final property access: 如果链式调用包含基数个元素,那么这个链式调用的结尾就是一个获取属性的操作: 代码语言:text AI代码解释 // equivalent to: take(3).cookies // ...
The pipe states where that line of the string really starts. Also, we can pass a Character or CharSequence as an argument to stripMargin with our custom delimiter character. Great, we got rid of all unnecessary whitespace, and our string contains only what we want! 4.5. Escaping Special ...
