Syntax

public sealed class Stream : DisposableGpuObject

Public NotInheritable Class Stream
	Inherits DisposableGpuObject

public ref class Stream sealed : public DisposableGpuObject

[<SealedAttribute>]
type Stream =  
    class
        inherit DisposableGpuObject
    end

The Stream type exposes the following members.

Constructors

	Name	Description
	Stream	Creates empty Stream
	Stream(IntPtr)	Creates from native cv::gpu::Stream* pointer
	Stream(Stream)	Initializes a new instance of the Stream class

Properties

	Name	Description
	CvPtr	Native pointer of OpenCV structure (Inherited from DisposableCvObject.)
	IsDisposed	Gets a value indicating whether this instance has been disposed. (Inherited from DisposableObject.)
	IsEnabledDispose	Gets or sets a value indicating whether you permit disposing this instance. (Inherited from DisposableObject.)
	Null	Empty stream

Methods

	Name	Description
	Dispose	Releases the resources (Inherited from DisposableObject.)
	EnqueueConvert	converts matrix type, ex from float to uchar depending on type
	EnqueueCopy	Copy asynchronously
	EnqueueDownload(GpuMat, CudaMem)	Downloads asynchronously. Warning! cv::Mat must point to page locked memory (i.e. to CudaMem data or to its subMat)
	EnqueueDownload(GpuMat, Mat)	Downloads asynchronously. Warning! cv::Mat must point to page locked memory (i.e. to CudaMem data or to its subMat)
	EnqueueHostCallback	Adds a callback to be called on the host after all currently enqueued items in the stream have completed
	EnqueueMemSet(GpuMat, Scalar)	Memory set asynchronously
	EnqueueMemSet(GpuMat, Scalar, GpuMat)	Memory set asynchronously
	EnqueueUpload(CudaMem, GpuMat)	Uploads asynchronously. Warning! cv::Mat must point to page locked memory (i.e. to CudaMem data or to its ROI)
	EnqueueUpload(Mat, GpuMat)	Uploads asynchronously. Warning! cv::Mat must point to page locked memory (i.e. to CudaMem data or to its ROI)
	Equals	(Inherited from Object.)
	GetHashCode	(Inherited from Object.)
	GetType	(Inherited from Object.)
	QueryIfComplete
	Release	Clean up any resources being used.
	ThrowIfDisposed	If this object is disposed, then ObjectDisposedException is thrown. (Inherited from DisposableObject.)
	ToString	(Inherited from Object.)
	WaitForCompletion

Operators
