constructor

new JsMemoryManager<V extends TypedArray = Float64Array<ArrayBufferLike>>(
Ctor?: TypedArrayConstructor<V>,
): JsMemoryManager<V>
Type Parameters
- V extends TypedArray = Float64Array<ArrayBufferLike>
Parameters
- Ctor: TypedArrayConstructor<V> = ...
  the typed-array constructor selecting the element type (default Float64Array).
Returns JsMemoryManager<V>
Overrides AbstractMemoryManager.constructor
- Defined in js/js/memory.ts:31

Accessors

buffer

get buffer(): ArrayBufferLike
The active memory buffer (== view.buffer). Retained for API compatibility.

Returns ArrayBufferLike
Inherited from AbstractMemoryManager.buffer
- Defined in js/memory.ts:169

view

get view(): V
The active typed-array memory view.

Returns V
Overrides AbstractMemoryManager.view
- Defined in js/js/memory.ts:37

Methods

allocate

allocate(size: number): TypedArrayPointer<V>
Allocates size elements and returns an owning, GC-registered pointer.
Parameters
- size: number
Returns TypedArrayPointer<V>
Inherited from AbstractMemoryManager.allocate
- Defined in js/memory.ts:179

`Protected`createRaw

createRaw(size: number): number
Allocates size elements and returns its byte offset.
Parameters
- size: number
Returns number
Overrides AbstractMemoryManager.createRaw
- Defined in js/js/memory.ts:44

free

free(ptr: TypedArrayPointer<V>): void
Releases a pointer previously produced by allocate. Idempotent.
Parameters
- ptr: TypedArrayPointer<V>
Returns void
Inherited from AbstractMemoryManager.free
- Defined in js/memory.ts:194

`Protected`freeRaw

freeRaw(byteOffset: number, size: number): void
Frees the region at byteOffset of size elements.
Parameters
- byteOffset: number
- size: number
Returns void
Overrides AbstractMemoryManager.freeRaw
- Defined in js/js/memory.ts:62

wrap

wrap(byteOffset: number, size: number): TypedArrayPointer<V>
Wraps an already-allocated raw offset as an owning, GC-registered pointer. Used by allocate and by the wasm binding, whose math ops allocate their result region inside wasm memory and hand back the raw offset.
Parameters
- byteOffset: number
- size: number
Returns TypedArrayPointer<V>
Inherited from AbstractMemoryManager.wrap
- Defined in js/memory.ts:188
