Enum Constants

Enum Constant	Description
MODERATE_SEMIPRIMES	Odd semiprimes N=a*b with min(a,b) >= cbrt(N).
QUITE_HARD_SEMIPRIMES	Odd semiprimes N=a*b with bitLength(min(a,b)) == bitLength(N)/2 - 1 bits.
RANDOM_COMPOSITES	Arbitrary random composite numbers N chosen from a certain bit length.
RANDOM_ODD_COMPOSITES	Random odd composite numbers N chosen from a certain bit length.

Enum Constant Detail

RANDOM_COMPOSITES

public static final TestNumberNature RANDOM_COMPOSITES

Arbitrary random composite numbers N chosen from a certain bit length. Note that there are no such numbers with less than 3 bits.

RANDOM_ODD_COMPOSITES

public static final TestNumberNature RANDOM_ODD_COMPOSITES

Random odd composite numbers N chosen from a certain bit length. Note that there are no such numbers with less than 4 bits.

MODERATE_SEMIPRIMES

public static final TestNumberNature MODERATE_SEMIPRIMES

Odd semiprimes N=a*b with min(a,b) >= cbrt(N). Note that there are no such numbers with less than 4 bits.

QUITE_HARD_SEMIPRIMES

public static final TestNumberNature QUITE_HARD_SEMIPRIMES

Odd semiprimes N=a*b with bitLength(min(a,b)) == bitLength(N)/2 - 1 bits.

Method Detail

values

public static TestNumberNature[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (TestNumberNature c : TestNumberNature.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static TestNumberNature valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
