• ### Method Summary

Methods
Modifier and Type Method and 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:
• #### 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.
