2、创建 Slice: 定义了 DataState 接口来表示状态结构。 使用createSlice 创建了一个名为 data 的 slice,包含初始状态和 reducers。 3、处理异步操作: fetchDataStart:设置 loadingState 为 Loading,并清空错误信息。 fetchDataSuccess:设置 loadingState 为 Success,并存储获取到的数据。 fetchDataFailed:设置 loading...
An enum type is a specialdata type. It enables for a variable to be asetof predefinedconstants. Because they are constants, the names of an enum type's fields are in UPPERCASE letters. For example, you can specify a days-of-the-week enum type as: publicenumDay { SUNDAY, MONDAY, TUE...
For example, If we want that each enum type ofDirectionshould be able to print the direction name with a custom message when needed. This can be done by defining aabstractmethod insideDirection, which each enum has to override. 5. Inheritance As mentioned earlier,enumextends Enumclass. Thejava...
Starting in PowerShell 6.2, you can define enumerations with a specific underlying type. This example shows the valid underlying types for an enumeration. The first code block initializes two variables as arrays. $EnumTypes is an empty array to hold the dynamically created types. $IntegralTypes...
You select the data type from this enumeration. The DataTypeAttribute attribute lets you mark fields by using a type that is more specific than the database intrinsic types. For example, a string data field that contains email addresses can be attributed with the EmailAddress enumerated value. ...
Name enum_type. The enumerated type, like any data type defined with TYPES, can be used with its name enum_type, for example, after a TYPE addition or in suitable constructor expressions. It acts as a full type in typing of field symbols or current parameters. ...
containing all of the values of the enum in the order they are declared. This method is commonly used in combination with the for-each construct to iterate over the values of an enum type. For example, this code from thePlanetclass example below iterates over all the planets in the solar...
If you are interfacing with a component that does not support this data type, you must replace it with the closest CLS-compliant type. For example, in place of UInteger you might be able to use Integer if you do not need the value range above 2,147,483,647...
