Method Detail

getFinal

public java.lang.String getFinal()

Description copied from class: AlgebraicEvalFunc

This must be implement as per a normal Algebraic interface. See Algebraic for more information.

Specified by:

getFinal in interface Algebraic

Specified by:

getFinal in class GroovyAlgebraicEvalFunc<java.math.BigInteger>

Returns:

A function name of f_final. f_final should be an eval func parametrized by the same datum as the eval func implementing this interface.
