Enum Constant Detail

CACHED

public static final GroupElement.Representation CACHED

Cached representation for intermediate calculations

P1P1

public static final GroupElement.Representation P1P1

Completed representation for addition results

P2

public static final GroupElement.Representation P2

Projective representation (X:Y:Z)

P3

public static final GroupElement.Representation P3

Extended projective representation (X:Y:Z:T)

P3PrecomputedDouble

public static final GroupElement.Representation P3PrecomputedDouble

Extended representation with precomputed doubles.

PRECOMP

Method Detail

valueOf

public static GroupElement.Representation 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

values

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

Returns:

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