Method Detail

plus

G plus(G that)

Returns the sum of this object with the one specified.

Parameters:

that - the object to be added.

Returns:

this + that.

opposite

G opposite()

Returns the additive inverse of this object. It is the object such as this.plus(this.opposite()) == ZERO, with ZERO being the additive identity.

Returns:

-this.
