Whether this object has been disposed.

Methods

dispose() → void

Releases the underlying native resources. Idempotent: calling it more than once is safe, but the object must not be used after dispose.

inherited

fill(Mat mat, int distType, double a, double b, {bool saturateRange = false, bool inplace = false}) → Mat

Fills arrays with random numbers. https://docs.opencv.org/4.x/d1/dd6/classcv_1_1RNG.html#ad26f2b09d9868cf108e84c9814aa682d

fillAsync(Mat mat, int distType, double a, double b, {bool saturateRange = false, bool inplace = false}) → Future<Mat>

Fills arrays with random numbers. https://docs.opencv.org/4.x/d1/dd6/classcv_1_1RNG.html#ad26f2b09d9868cf108e84c9814aa682d

freeNative() → void

Frees the native resources owned by this object. Subclasses implement the concrete free logic here; callers must use dispose instead.

override

gaussian(double sigma, {int? maxCount}) → Stream<double>

The method transforms the state using the MWC algorithm and returns the next random number from the Gaussian distribution N(0,sigma) . That is, the mean value of the returned random numbers is zero and the standard deviation is the specified sigma . https://docs.opencv.org/4.x/d1/dd6/classcv_1_1RNG.html#a8df8ce4dc7d15916cee743e5a884639d

next({int? maxCount}) → Stream<int>

The method updates the state using the MWC algorithm and returns the next 32-bit random number. https://docs.opencv.org/4.x/d1/dd6/classcv_1_1RNG.html#ad8d035897a5e31e7fc3e1e6c378c32f5

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

uniform(num a, num b, {int? maxCount}) → Stream<num>

returns uniformly distributed integer random number from [a,b) range The methods transform the state using the MWC algorithm and return the next uniformly-distributed random number of the specified type, deduced from the input parameter type, from the range [a, b) . https://docs.opencv.org/4.x/d1/dd6/classcv_1_1RNG.html#a8325cc562269b47bcac2343639b6fafc

Operators

operator ==(Object other) → bool

The equality operator.
