init

TypeScript

static init(allocationThreshold?: (number) | null): CVMutablePixelBuffer_Pool_AllocationAttributes

Swift declaration

init(allocationThreshold: Int? = nil)

allocationThreshold

TypeScript

get allocationThreshold(): (number) | null

Swift declaration

var allocationThreshold: Int?

A new pixel buffer will not be allocated if the pool already has this many or more pixel buffers allocated. This does not prevent already-allocated buffers from being recycled. If this causes allocation failure, then ``CVMutablePixelBuffer/Pool/mutablePixelBuffer(allocationThreshold:)`` throws ``CVError/wouldExceedAllocationThreshold``.

set · iOS 26.0+

allocationThreshold

TypeScript

set allocationThreshold(value: (number) | null)
