在Administration类中,为了管理与之相关联的实体,使用了OneToOneAssociation。 在JAVA中,OneToOneAssociation可以在实体类的构造函数中创建,并且可以通过相应的getter和setter方法访问。
以下是代码示例:
// Administration类
public class Administration {
private OneToOneAssociation building;
public Administration(Building building) {
this.building = new OneToOneAssociation<>(building);
}
public void setBuilding(Building building) {
this.building.setAssociation(building);
}
public Building getBuilding() {
return building.getAssociation();
}
}
// Building类
public class Building {
private String name;
public Building(String name) {
this.name = name;
}
public String getName() {
return this.name;
}
}
这里,Administration类有一个OneToOneAssociation,它与Building类关联。在Administration的构造函数中,我们通过OneToOneAssociation的构造函数将建筑物与Administration关联起来。在setBuilding()和getBuilding()方法中,我们可以访问OneToOneAssociation以获取或设置与Administration相关联的建筑物。
