修改方法的属性

## 方法抛出异常 ##

raisedExceptions：表示方法抛出的异常，需要新创建一个异常类：

点击搜索按钮，会弹出一个对话框：

点击 add，选择刚才创建的异常类：

如果有多个，还可以调整顺序，调整完之后，点击close，此时在属性设置那里会出现：

# concurrency #

这个没有用过

# 查询方法isQuery #

isQuery：代表该方法是否是查询方法，如果是的话，在类图上的表现是添加\{query\}：

# 抽象方法isAbstract #

isAbstract:标识该方法是否是抽象方法，如果选择是，在类图中的表现是所有的字都是斜的：

# 方法的返回值 #

选中方法，右键，选择add->parameter；

![在这里插入图片描述][20200605175356600.png]  
在model explorer里会看到多了一个Parameter1：

选中它，修改它的两个属性：type(返回值的类型)、direction(设置返回值)。  
direction设置成 return，type设置成需要的类型：

# 方法的参数 #

与设置返回值类似，但direction，调整为 in，并且name也要设置：
