OverlappingTemplateMatchingsTest (Overlapping Template Matchings Random Test)

OverlappingTemplateMatchingsTest Class

Derived class from: BaseRandomTest

Implements the OverlappingTemplateMatchings random test.

The class contains:

Class Constructors & Destructor

		OverlappingTemplateMatchingsTest ();
		Creates an object of the class, sets the default values for members and creates the MathematicalFunctions object needed to execute the random test.

OverlappingTemplateMatchingsTest (MathematicalFunctions* functions);

Creates an object of the class, sets the default values for members and sets the MathematicalFunctions object functions passed as the MathematicalFunctions object needed to execute the random test.
		If no MathematicalFunctions object functions is passed (NULL value), the constructor creates by itself the corresponding MathematicalFunctions object.

~OverlappingTemplateMatchingsTest ();

Destroys the object and clears all members.
		If a MathematicalFunctions object has been created when the object was created, the MathematicalFunctions object is destroyed. If the MathematicalFunctions object was provided as a parameter, the MathematicalFunctions object is not deleted !!!.

Class Initializers

		void Initialize (void); [ Inherited from BaseRandomTest ]
		Sets the default values to all members, the object is cleaned. The MathematicalFunctions object is not affected.

Class Methods

		*void SetAlpha (double alpha);* [ Inherited from BaseRandomTest ]
		Sets the alpha value for the random test object. Alpha is the significance level that determines the region of acceptance and rejection. For example, if alpha is set to >= 0,001 then we are demanding a confidence level of 99,9%.

		*bool IsRandom (BaseCryptoRandomStream stream);** [ Overridden, BaseRandomTest virtual method defined ]
		Performs the specific randomness test. Checks randomness of BaseCryptoRandomStream stream parameter and returns 0 (false randomness) or 1 (true randomness).

		bool IsRandom (void); [ Inherited from BaseRandomTest ]
		Gets randomness of the last checked BaseCryptoRandomStream , returns 0 (false randomness) or 1 (true randomness).

		double GetPValue (void); [ Inherited from BaseRandomTest ]
		Gets PValue of the last checked BaseCryptoRandomStream . PValue is the probability that a perfect random number generator would have produced a sequence less random than the BaseCryptoRandomStream checked, given the kind of non-randomness assessed by the test.

		double GetAlpha (void); [ Inherited from BaseRandomTest ]
		Gets the alpha of the random test object.

		RandomTests GetType (void); [ Overridden, BaseRandomTest virtual method defined ]
		Gets the random test type (the algorithm that implements) of the object. Returns the corresponding RandomTests value.

		unsigned int GetMinimumLength (void); [ Overridden, BaseRandomTest virtual method defined ]
		Gets the minimum length that the BaseCryptoRandomStream must have in order to perform the random test.

		RandomTestErrors GetError (void); [ Inherited from BaseRandomTest ]
		Gets the error of the last checked BaseCryptoRandomStream . Returns one of the RandomTestErrors values. If no error has been produced, the value is set to NoError.

Specific Class Methods

		*int GetWindowLengths (void);**
		Gets an array of block sizes.

		*void SetWindowLength (int windowLength);*
		Sets the window length windowLength parameter.

		int GetWindowLength (void);
		Gets the window length result.

		int GetM (void);
		Gets the "M" result.

		int GetN (void);
		Gets the "N" result.

		double GetChiSquared (void);
		Gets the chiSquared result.

		double GetEta (void);
		Gets the "eta" result.

		double GetLambda (void);
		Gets the "lambda" result.

		*void GetAssignment (unsigned int assignmentsArray);**
		Gets the assignment array assignmentsArray (minimum array lenght is 6) result.

		*unsigned int GetAssignmentOfIndex (int index);*
		Gets the assignment result by index index (index must be between 0 and 5).
