Often developers will add many fields to classes without realizing that each int field they add to a class will be multiplied by a large factor (the number of instances) at run time.
通常,开发人员会为类添加很多字段,而未意识到为类所添加的每个整型字段都会在运行时与一个较大的因数(实例数量)相乘。
For example, as shown in the figure, we are trying to add a text input field with the name "tel" and the value of "tel" should be of type int.
例如,我们按照图中所示的一样视图添加一个文本输入域:该域名为“tel”,值为“tel”,类型为int。
To create a template class such as template class one
要创建一个模板类,例如:templateclassone
Here we will add three fields: id, name, and address of types int, text, and text, respectively. Your screen should look like this.
我们将在这里添加3个域:id、name和address,类型分别为int、text和text。
Create a UML class class1 and add an operation op with return type int to it.
创建一个uml类class1,并且向其添加一个操作op,其返回值类型为int。
Right-click the class and add a template parameter with name T. Add operations such as isEmpty():bool ,getSize():int.
在此类上右击并添加一个名为T的模板参数。 添加诸如isEmpty():bool ,getSize():int之类的操作。
Add two parameters of type int to the operation, and name them row and column.
向操作添加两个int类型的参数,并将其命名为row和column。
Add another method, and name it parse_line, with two input parameters - line and argv - along with a return parameter with int as the type. (see Figure 5).
添加另外一种方法,并将其命名为parse_line,其两个输入参数为—line和argv—以及一个int的返回参数(见于图5)。
Add a method called get with return type as the template parameter t from the method (as shown in Figure 4), and an input parameter named index whose type is int.
添加一个名为get的方法。在此方法中,使其返回类型为模板参数t(如图4所示),然后输入参数名字index,其类型为int。
Add a public field named distance to Point, and set its type to int.
向Point添加名为distance的public字段,并将其类型设置为int。
Add a String field called name and an int field called id.
添加名为name的String字段和名为id的int字段。
Note that a numeric addition has occurred because the input parameter to the add function is bound to an int type argument at function execution time. Now, try this.
请注意,由于add函数的输入参数在运行时被绑定到int类自变量,因此产生了数值的增加。
