Class AbstractMemoryManager<V>`Abstract`

Base class for MemoryManagers. Implements allocate/free plus the embedded FinalizationRegistry that reclaims dropped pointers. Concrete managers implement createRaw/freeRaw and the view getter.

Type Parameters

V extends TypedArray = Float64Array

constructor

new AbstractMemoryManager<V extends TypedArray = Float64Array<ArrayBufferLike>>(
useFinalizationRegistry?: boolean,
): AbstractMemoryManager<V>
Type Parameters
- V extends TypedArray = Float64Array<ArrayBufferLike>
Parameters
- useFinalizationRegistry: boolean = true
  when true (default) dropped pointers are reclaimed automatically via a FinalizationRegistry (when available).
Returns AbstractMemoryManager<V>
- Defined in js/memory.ts:159

Accessors

buffer

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

Returns ArrayBufferLike
Implementation of MemoryManager.buffer
- Defined in js/memory.ts:169

`Abstract`view

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

Returns V
Implementation of MemoryManager.view
- Defined in js/memory.ts:167

Methods

allocate

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

`Protected` `Abstract`createRaw

createRaw(size: number): number
Allocates size elements and returns its byte offset.
Parameters
- size: number
Returns number
- Defined in js/memory.ts:174

free

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

`Protected` `Abstract`freeRaw

freeRaw(byteOffset: number, size: number): void
Frees the region at byteOffset of size elements.
Parameters
- byteOffset: number
- size: number
Returns void
- Defined in js/memory.ts:177

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>
- Defined in js/memory.ts:188
