Method Summary

Modifier and Type	Method	Description
T	getOne()	Get the multiplicative identity of the field.
Class<? extends FieldElement<T>>	getRuntimeClass()	Returns the runtime class of the FieldElement.
T	getZero()	Get the additive identity of the field.

Method Detail

getZero

T 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.

Returns:

additive identity of the field

getOne

T 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.

Returns:

multiplicative identity of the field

getRuntimeClass

Class<? extends FieldElement<T>> getRuntimeClass()

Returns the runtime class of the FieldElement.

Returns:

The Class object that represents the runtime class of this object.
