Enum Constant Detail

BINARY_FIELD

public static final FieldTypes BINARY_FIELD

Denotes fields of characteristic 2.

PRIME_FIELD

public static final FieldTypes PRIME_FIELD

Denotes fields of prime characteristic. This is usually the fastest type of fields to be used in software.

EXTENSION_FIELD

public static final FieldTypes EXTENSION_FIELD

Denotes field extensions of prime characteristic fields.

Method Detail

values

public static FieldTypes[] 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 (FieldTypes c : FieldTypes.values())
    System.out.println(c);

Returns:

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

valueOf

public static FieldTypes 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
