Syntax

• @memberof <parentNamepath>
• @memberof! <parentNamepath>

Overview

The @memberof tag identifies a member symbol that belongs to a parent symbol.

By default, the @memberof tag documents member symbols as static members. For inner and instance members, you can use scoping punctuation after the namepath, or you can add the @inner or @instance tag.

The "forced" @memberof tag, @memberof!, forces the object to be documented as belonging to a specific parent even if it appears to have a different parent.

Examples

In the following example, the hammer function would normally be documented as a global function. That's because, in fact, it is a global function, but it is also a member of the Tools namespace, and that's how you wish to document it. The solution is to add a @memberof tag:

/** @namespace */
var Tools = {};

/** @memberof Tools */
var hammer = function() {
};

Tools.hammer = hammer;

For instance members of a class, use the syntax "@memberof ClassName.prototype" or "@memberof ClassName#". Alternatively, you can combine "@memberof ClassName" with the "@instance" tag.

/** @class Observable */
create(
    'Observable',
    {
        /**
         * This will be a static member, Observable.cache.
         * @memberof Observable
         */
        cache: [],

        /**
         * This will be an instance member, Observable#publish.
         * @memberof Observable.prototype
         */
        publish: function(msg) {},

        /**
         * This will also be an instance member, Observable#save.
         * @memberof Observable#
         */
        save: function() {},

        /**
         * This will also be an instance member, Observable#end.
         * @memberof Observable
         * @instance
         */
        end: function() {}
    }
);

The following example uses the forced @memberof tag, "@memberof!", to document a property of an object (Data#point) that is an instance member of a class (Data).

When you use the @property tag to document a property, you cannot link to the property using its longname. We can force the property to be linkable by using "@alias" and "@memberof!" to tell JSDoc that Data#point.y should be documented as a member "point.y" of "Data#", rather than a member "y" of "point" of "Data#".

/** @class */
function Data() {
    /**
     * @type {object}
     * @property {number} y This will show up as a property of `Data#point`,
     * but you cannot link to the property as {@link Data#point.y}.
     */
    this.point = {
        /**
         * The @alias and @memberof! tags force JSDoc to document the
         * property as `point.x` (rather than `x`) and to be a member of
         * `Data#`. You can link to the property as {@link Data#point.x}.
         * @alias point.x
         * @memberof! Data#
         */
        x: 0,
        y: 1
    };
}
