Method Details
-
getInstance
Get the unique instance.- Returns:
- the unique instance
-
getOne
Get the multiplicative identity of the field.The multiplicative identity is the element e1 of the field such that for all elements a of the field, the equalities a × e1 = e1 × a = a hold.
-
getZero
Get the additive identity of the field.The additive identity is the element e0 of the field such that for all elements a of the field, the equalities a + e0 = e0 + a = a hold.
-
getRuntimeClass
Returns the runtime class of the FieldElement.- Specified by:
getRuntimeClass
in interfaceField<BigReal>
- Returns:
- The
Class
object that represents the runtime class of this object.
-
readResolve
Handle deserialization of the singleton.- Returns:
- the singleton instance
