Detailed Description

Represents a pseudo-random number generator. Objects of this class should only be allocated using System::MakeObject() function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into System::SmartPtr pointer and use this pointer to pass it to functions as argument.

Constructor & Destructor Documentation

Random() [1/2]

ASPOSECPP_SHARED_API System::Random::Random

(

)

Initializes a new instance, using a time-dependent default seed value.

Random() [2/2]

ASPOSECPP_SHARED_API System::Random::Random

(

int32_t

seed

)

Initializes a new instance of the System.Random class, using the specified seed value.

Parameters

seed	The seed used to generate a pseudo-random number sequence

Member Function Documentation

IsNull()

bool System::Random::IsNull ( ) const

inline

Always returns false.

Next() [1/3]

ASPOSECPP_SHARED_API int32_t System::Random::Next

(

)

Returns a nonnegative random number less then int32 max value.

Next() [2/3]

ASPOSECPP_SHARED_API int32_t System::Random::Next

(

int32_t

maxValue

)

Returns a nonnegative random number less than the specified maximum.

Parameters

maxValue

Values generated by the method will be less than this value

Next() [3/3]

ASPOSECPP_SHARED_API int32_t System::Random::Next	(	int32_t	minValue,
		int32_t	maxValue
	)

Returns a random number within the specified range.

Parameters

minValue	Values generated by the method will be greater than this value
maxValue	Values generated by the method will be less than this value

NextBytes()

ASPOSECPP_SHARED_API void System::Random::NextBytes

(

const ArrayPtr< uint8_t > &

buffer

)

Fills the elements of the specified array of bytes with random numbers.

Parameters

buffer

The array to fill

NextDouble()

(

)

Returns a random number between 0.0 and 1.0.

operator=()

Random& System::Random::operator= ( std::nullptr_t  )

inline

Effectively does nothing.

Returns

A reference to the self
