関数詳解

bind()

void cv::ocl::OpenCLExecutionContext::bind

(

)

const

Bind this OpenCL execution context to current thread.

Context can't be empty.

覚え書き

clFinish is not called for queue of previous execution context

cloneWithNewQueue() [1/2]

OpenCLExecutionContext cv::ocl::OpenCLExecutionContext::cloneWithNewQueue

(

)

const

これはオーバーロードされたメンバ関数です。利便性のために用意されています。元の関数との違いは引き数のみです。

cloneWithNewQueue() [2/2]

OpenCLExecutionContext cv::ocl::OpenCLExecutionContext::cloneWithNewQueue

(

const ocl::Queue &

q

)

const

Creates new execution context with same OpenCV context and device

引数

q	OpenCL queue

create() [1/3]

static OpenCLExecutionContext cv::ocl::OpenCLExecutionContext::create ( const Context &  context, const Device &  device  )

static

これはオーバーロードされたメンバ関数です。利便性のために用意されています。元の関数との違いは引き数のみです。

create() [2/3]

static OpenCLExecutionContext cv::ocl::OpenCLExecutionContext::create ( const Context &  context, const Device &  device, const ocl::Queue &  queue  )

static

Creates OpenCL execution context

引数

context	non-empty OpenCL context
device	non-empty OpenCL device (must be a part of context)
queue	non-empty OpenCL queue for provided context and device

create() [3/3]

static OpenCLExecutionContext cv::ocl::OpenCLExecutionContext::create ( const std::string &  platformName, void *  platformID, void *  context, void *  deviceID  )

static

Creates OpenCL execution context OpenCV will check if available OpenCL platform has platformName name, then assign context to OpenCV and call clRetainContext function. The deviceID device will be used as target device and new command queue will be created.

覚え書き

Lifetime of passed handles is transferred to OpenCV wrappers on success

引数

platformName	name of OpenCL platform to attach, this string is used to check if platform is available to OpenCV at runtime
platformID	ID of platform attached context was created for (cl_platform_id)
context	OpenCL context to be attached to OpenCV (cl_context)
deviceID	OpenCL device (cl_device_id)

getContext()

Context & cv::ocl::OpenCLExecutionContext::getContext

(

)

const

Get associated ocl::Context

getCurrent()

static OpenCLExecutionContext & cv::ocl::OpenCLExecutionContext::getCurrent ( )

static

Get OpenCL execution context of current thread.

Initialize OpenCL execution context if it is empty

• create new
• reuse context of the main thread (threadID = 0)

getCurrentRef()

static OpenCLExecutionContext & cv::ocl::OpenCLExecutionContext::getCurrentRef ( )

static

Get OpenCL execution context of current thread (can be empty)

getDevice()

Device & cv::ocl::OpenCLExecutionContext::getDevice

(

)

const

Get the single default associated ocl::Device

getQueue()

Queue & cv::ocl::OpenCLExecutionContext::getQueue

(

)

const

Get the single ocl::Queue that is associated with the ocl::Context and the single default ocl::Device
