詳解

Returns result of asynchronous operations

Object has attached asynchronous state. Assignment operator doesn't clone asynchronous state (it is shared between all instances).

Result can be fetched via get() method only once.

関数詳解

get() [1/2]

CV_WRAP void cv::AsyncArray::get

(

OutputArray

dst

)

const

Fetch the result.

引数

[out]

dst

destination array

Waits for result until container has valid result. Throws exception if exception was stored as a result.

Throws exception on invalid container state.

覚え書き

Result or stored exception can be fetched only once.

get() [2/2]

bool cv::AsyncArray::get	(	OutputArray	dst,
		int64	timeoutNs
	)		const

Retrieving the result with timeout

引数

[out]	dst	destination array
[in]	timeoutNs	timeout in nanoseconds, -1 for infinite wait

戻り値

true if result is ready, false if the timeout has expired

覚え書き

Result or stored exception can be fetched only once.
