A mask is an object that limits the visibility of an\n * object to the shape of the mask applied to it. In PixiJS a regular mask must be a\n * {@link PIXI.Graphics} or a {@link PIXI.Sprite} object. This allows for much faster masking in canvas as it\n * utilities shape clipping. To remove a mask, set this property to `null`.\n *\n * For sprite mask both alpha and red channel are used. Black mask is the same as transparent mask.\n * @example\n * const graphics = new PIXI.Graphics();\n * graphics.beginFill(0xFF3300);\n * graphics.drawRect(50, 250, 100, 100);\n * graphics.endFill();\n *\n * const sprite = new PIXI.Sprite(texture);\n * sprite.mask = graphics;\n * @todo At the moment, PIXI.CanvasRenderer doesn't support PIXI.Sprite as mask.\n *\n * @member {PIXI.Container|PIXI.MaskData|null}\n */\n get mask(): Container|MaskData|null\n {\n return this._mask;\n }\n\n set mask(value: Container|MaskData|null)\n {\n if (this._mask)\n {\n const maskObject = ((this._mask as MaskData).maskObject || this._mask) as Container;\n\n maskObject.renderable = true;\n maskObject.isMask = false;\n }\n\n this._mask = value;\n\n if (this._mask)\n {\n const maskObject = ((this._mask as MaskData).maskObject || this._mask) as Container;\n\n maskObject.renderable = false;\n maskObject.isMask = true;\n }\n }\n}\n\nexport class TemporaryDisplayObject extends DisplayObject\n{\n calculateBounds: () => null;\n removeChild: (child: DisplayObject) => null;\n render: (renderer: Renderer) => null;\n sortDirty: boolean = null;\n}\n\n/**\n * DisplayObject default updateTransform, does not update children of container.\n * Will crash if there's no parent element.\n *\n * @memberof PIXI.DisplayObject#\n * @function displayObjectUpdateTransform\n */\nDisplayObject.prototype.displayObjectUpdateTransform = DisplayObject.prototype.updateTransform;\n","import { settings } from '@pixi/settings';\nimport { removeItems } from '@pixi/utils';\nimport { DisplayObject } from './DisplayObject';\nimport { Rectangle } from '@pixi/math';\n\nimport type { MaskData, Renderer } from '@pixi/core';\nimport type { IDestroyOptions } from './DisplayObject';\n\nfunction sortChildren(a: DisplayObject, b: DisplayObject): number\n{\n if (a.zIndex === b.zIndex)\n {\n return a._lastSortedIndex - b._lastSortedIndex;\n }\n\n return a.zIndex - b.zIndex;\n}\n\nexport interface Container extends GlobalMixins.Container, DisplayObject {}\n\n/**\n * A Container represents a collection of display objects.\n *\n * It is the base class of all display objects that act as a container for other objects (like Sprites).\n *\n *```js\n * let container = new PIXI.Container();\n * container.addChild(sprite);\n * ```\n *\n * @class\n * @extends PIXI.DisplayObject\n * @memberof PIXI\n */\nexport class Container extends DisplayObject\n{\n public readonly children: DisplayObject[];\n public sortableChildren: boolean;\n public sortDirty: boolean;\n public containerUpdateTransform: () => void;\n\n protected _width: number;\n protected _height: number;\n\n constructor()\n {\n super();\n\n /**\n * The array of children of this container.\n *\n * @member {PIXI.DisplayObject[]}\n * @readonly\n */\n this.children = [];\n\n /**\n * If set to true, the container will sort its children by zIndex value\n * when updateTransform() is called, or manually if sortChildren() is called.\n *\n * This actually changes the order of elements in the array, so should be treated\n * as a basic solution that is not performant compared to other solutions,\n * such as @link https://github.com/pixijs/pixi-display\n *\n * Also be aware of that this may not work nicely with the addChildAt() function,\n * as the zIndex sorting may cause the child to automatically sorted to another position.\n *\n * @see PIXI.settings.SORTABLE_CHILDREN\n *\n * @member {boolean}\n */\n this.sortableChildren = settings.SORTABLE_CHILDREN;\n\n /**\n * Should children be sorted by zIndex at the next updateTransform call.\n * Will get automatically set to true if a new child is added, or if a child's zIndex changes.\n *\n * @member {boolean}\n */\n this.sortDirty = false;\n\n /**\n * Fired when a DisplayObject is added to this Container.\n *\n * @event PIXI.Container#childAdded\n * @param {PIXI.DisplayObject} child - The child added to the Container.\n * @param {PIXI.Container} container - The container that added the child.\n * @param {number} index - The children's index of the added child.\n */\n\n /**\n * Fired when a DisplayObject is removed from this Container.\n *\n * @event PIXI.DisplayObject#removedFrom\n * @param {PIXI.DisplayObject} child - The child removed from the Container.\n * @param {PIXI.Container} container - The container that removed removed the child.\n * @param {number} index - The former children's index of the removed child\n */\n }\n\n /**\n * Overridable method that can be used by Container subclasses whenever the children array is modified\n *\n * @protected\n */\n protected onChildrenChange(_length: number): void\n {\n /* empty */\n }\n\n /**\n * Adds one or more children to the container.\n *\n * Multiple items can be added like so: `myContainer.addChild(thingOne, thingTwo, thingThree)`\n *\n * @param {...PIXI.DisplayObject} children - The DisplayObject(s) to add to the container\n * @return {PIXI.DisplayObject} The first child that was added.\n */\n addChild
