Constructor Detail

ChaosKeyImpl

public ChaosKeyImpl(String aSecret)

Instantiates a new chaos key by calculating x0, a and s from the provided String.

Parameters:

aSecret - The String from which to calculate x0, a and s.

ChaosKeyImpl

public ChaosKeyImpl(int x0,
                    int a,
                    int s)

Instantiates a new chaos key from the provided integer values. The integers are converted to the valid ranges of double values for invoking the constructor ChaosKeyImpl(double, double, double). You can use values in the range of Integer.MIN_VALUE and Integer.MAX_VALUE.

Parameters:

x0 - The value from which to calculate the valid x0 double.

a - The value from which to calculate the valid a double.

s - The value from which to calculate the valid s double.

ChaosKeyImpl

public ChaosKeyImpl(double x0,
                    double a,
                    double s)

Instantiates a new chaos key.

Parameters:

x0 - the x0: (0 <= x0 <= 1 )

a - the a: (a <= 3.57 <= 4 )

s - the s: (s > Integer.MAX_VALUE)

toX0

protected static double toX0(int x0)

Creates a valid x0 double from the provided integer (values from Integer.MIN_VALUE to Integer.MAX_VALUE are allowed.

Parameters:

x0 - The integer as source for x0

Returns:

The x0 inside the valid scope.

toA

protected static double toA(int a)

Creates a valid a double from the provided integer (values from Integer.MIN_VALUE to Integer.MAX_VALUE are allowed.

Parameters:

a - The integer as source for a

Returns:

toS

protected static double toS(int s)

Creates a valid s double from the provided integer (values from Integer.MIN_VALUE to Integer.MAX_VALUE are allowed.

Parameters:

s - The integer as source for s

Returns:

The s inside the valid scope.

validate

protected static void validate(double x0,
                               double a,
                               double s)

Validates the given values whether them are in scope.

Parameters:

x0 - The x0 value to validate.

a - The a value to validate.

s - The s value to validate.
