很简单用private修饰符,后面跟限制关键字set: class Day{ private(set) var rawValue:Int = 0 func showRawValue(){ print("raw is \(rawValue)") } func forwardRawValue(){ rawValue += 1 } } 不过如上上述类定义在playground中的话,实际你会发现如果去掉后面的(set)照样可以在外部访问: let day = Day() day.rawVal…

如何创建一个要素数据类 创建要素类用到了IFeatureWorkspace.CreateFeatureClass方法,在这个方法中有众多的参数,为了满足这些参数,我们要学习和了解下面的接口. IField,IFieldEdit,IFields,IFieldsEditI,GeometryDef,IGeometryDefEdit接口 字段对应表中的一列,一个要素类必须有至少2个字段,而多个字段的集合就构成了字段集,在要素类中,有一个特殊的字段,描述了空间对象,我们称之为几何字段,其中Geometry…
