All Implemented Interfaces:
Serializable, Comparable<GroupElement.Representation>, java.lang.constant.Constable
Enclosing class:
GroupElement

public static enum GroupElement.Representation extends Enum<GroupElement.Representation>
Available representations for a group element.
  • P2: Projective representation $(X:Y:Z)$ satisfying $x=X/Z, y=Y/Z$.
  • P3: Extended projective representation $(X:Y:Z:T)$ satisfying $x=X/Z, y=Y/Z, XY=ZT$.
  • P3PrecomputedDouble: P3 but with dblPrecmp populated.
  • P1P1: Completed representation $((X:Z), (Y:T))$ satisfying $x=X/Z, y=Y/T$.
  • PRECOMP: Precomputed representation $(y+x, y-x, 2dxy)$.
  • CACHED: Cached representation $(Y+X, Y-X, Z, 2dT)$

    • values

      public static GroupElement.Representation[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared
    • 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
