JSDoc:オブジェクト構造を返す
返されるオブジェクトの構造についてJSDocに伝えるにはどうすればよいですか。私は@return {{field1: type, field2: type, ...}} description
構文を見つけて試しました:
/**
* Returns a coordinate from a given mouse or touch event
* @param {TouchEvent|MouseEvent|jQuery.Event} e
* A valid mouse or touch event or a jQuery event wrapping such an
* event.
* @param {string} [type="page"]
* A string representing the type of location that should be
* returned. Can be either "page", "client" or "screen".
* @return {{x: Number, y: Number}}
* The location of the event
*/
var getEventLocation = function(e, type) {
...
return {x: xLocation, y: yLocation};
}
これは正常に解析されますが、結果のドキュメントには次のように記載されています。
Returns:
The location of an event
Type: Object
APIを開発しているので、返されるオブジェクトについて人々に知ってもらう必要があります。これはJSDocで可能ですか? JSDoc3.3.0-beta1を使用しています。
個別に定義:
/**
* @typedef {Object} Point
* @property {number} x - The X Coordinate
* @property {number} y - The Y Coordinate
*/
そして使用:
/**
* Returns a coordinate from a given mouse or touch event
* @param {TouchEvent|MouseEvent|jQuery.Event} e
* A valid mouse or touch event or a jQuery event wrapping such an
* event.
* @param {string} [type="page"]
* A string representing the type of location that should be
* returned. Can be either "page", "client" or "screen".
* @return {Point}
* The location of the event
*/
var getEventLocation = function(e, type) {
...
return {x: xLocation, y: yLocation};
}
きれいな解決策は、クラスを作成して返すことです。
/**
* @class Point
* @type {Object}
* @property {number} x The X-coordinate.
* @property {number} y The Y-coordinate.
*/
function Point(x, y) {
return {
x: x,
y: y
};
}
/**
* @returns {Point} The location of the event.
*/
var getEventLocation = function(e, type) {
...
return new Point(x, y);
};
すでに投稿されている提案の代替として、次の形式を使用できます。
/**
* Get the connection state.
*
* @returns {Object} connection The connection state.
* @returns {boolean} connection.isConnected Whether the authenticated user is currently connected.
* @returns {boolean} connection.isPending Whether the authenticated user's connection is currently pending.
* @returns {Object} connection.error The error object if an error occurred.
* @returns {string} connection.error.message The error message.
* @returns {string} connection.error.stack The stack trace of the error.
*/
getConnection () {
return {
isConnected: true,
isPending: false,
error
}
}
次のドキュメント出力が得られます。
Get the connection state.
getConnection(): Object
Returns
Object: connection The connection state.
boolean: connection.isConnected Whether the authenticated user is currently connected.
boolean: connection.isPending Whether the authenticated users connection is currently pending.
Object: connection.error The error object if an error occurred.
string: connection.error.message The error message.
string: connection.error.stack The stack trace of the error.
