GPUHardwareBufferWrapper

Kotlin |Java

@ExperimentalWebGpuApi
abstract class GPUHardwareBufferWrapper : AutoCloseable

Known direct subclasses

`GPUHardwareBufferExternalTexture`
`GPUHardwareBufferTexture`

Base abstract wrapper for imported hardware buffers. Manages the native handle and synchronization fences for accessing the buffer.

Summary

Public constructors
`GPUHardwareBufferWrapper(handle: Long)`

Public functions
`Unit`	`beginAccess(fences: Array<GPUSyncFence>?)` Begins access to the hardware buffer, passing any wait fences to the native layer.
`open Unit`	`close()`
`GPUSyncFence?`	`endAccess()` Ends access to the hardware buffer, returning a signal fence from the native layer.

Protected functions
`external Unit`	`nativeBeginAccess(handle: Long, fences: IntArray?)`
`external Unit`	`nativeDestroy(handle: Long)`
`external Int`	`nativeEndAccess(handle: Long)`

GPUHardwareBufferWrapper(handle: Long)

fun beginAccess(fences: Array<GPUSyncFence>?): Unit

Begins access to the hardware buffer, passing any wait fences to the native layer.

Parameters
`fences: Array<GPUSyncFence>?`	Array of GPUSyncFence objects to wait on before accessing the buffer.

open fun close(): Unit

fun endAccess(): GPUSyncFence?

Ends access to the hardware buffer, returning a signal fence from the native layer.

Returns
`GPUSyncFence?`	GPUSyncFence that will be signaled when WebGPU is done with the buffer.
