@codexo/exojs / math / stable

A Size subclass that fires a callback whenever `width` or `height` changes. Used internally by layout-aware types to invalidate cached geometry on dimension mutations. Batch mutations via `set()` fire at most one callback per call.

Import

import { ObservableSize } from '@codexo/exojs'

A Size subclass that fires a callback whenever `width` or `height` changes. Used internally by layout-aware types to invalidate cached geometry on dimension mutations.

Batch mutations via `set()` fire at most one callback per call.

Methods9

add(x: number, y: number): this

clone(): SizeMutable 2D size (width × height) value type. All arithmetic methods mutate in place and return `this` for chaining. When `height` is omitted from `set`, `add`,…

A plain, callback-free Size. A clone is a value, not a second observer of this size's owner: mutating the copy must not invalidate geometry that belongs to something else. The return type says so, so a caller cannot mistake the copy for a live one.

copy(size: SizeMutable 2D size (width × height) value type. All arithmetic methods mutate in place and return `this` for chaining. When `height` is omitted from `set`, `add`,…): this

destroy(): void

divide(x: number, y: number): this

equals(__namedParameters: Partial<SizeMutable 2D size (width × height) value type. All arithmetic methods mutate in place and return `this` for chaining. When `height` is omitted from `set`, `add`,…>): boolean

scale(x: number, y: number): this

set(width: number, height: number): this

subtract(x: number, y: number): this
