GPUHardwareBufferWrapper

Kotlin |Java

@ExperimentalWebGpuApi
public abstract class GPUHardwareBufferWrapper implements 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(long handle)`

Public methods
`final void`	`beginAccess(GPUSyncFence[] fences)` Begins access to the hardware buffer, passing any wait fences to the native layer.
`void`	`close()`
`final GPUSyncFence`	`endAccess()` Ends access to the hardware buffer, returning a signal fence from the native layer.

Protected methods
`final external void`	`nativeBeginAccess(long handle, int[] fences)`
`final external void`	`nativeDestroy(long handle)`
`final external int`	`nativeEndAccess(long handle)`

public GPUHardwareBufferWrapper(long handle)

public final void beginAccess(GPUSyncFence[] fences)

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

Parameters
`GPUSyncFence[] fences`	Array of GPUSyncFence objects to wait on before accessing the buffer.

public void close()

public final GPUSyncFence endAccess()

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.
