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

OpenCvSharp.Cuda.Stream = function();

Type.createClass(
	'OpenCvSharp.Cuda.Stream',
	OpenCvSharp.Cuda.DisposableGpuObject);

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	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	Uploads asynchronously. Warning! cv::Mat must point to page locked memory (i.e. to CudaMem data or to its ROI)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (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	Returns a string that represents the current object. (Inherited from Object.)
	WaitForCompletion

Operators

	Name	Description
	(Stream to Boolean)
