Modifier and Type	Method	Description
static <A> IsEq<A>	IsEq.isEq(A lhs, A rhs)	Two equal elements
IsEq<A>	MonoidLaws.monoidLeftIdentity(A x)	If the zero of your monoid is combine with an element of the type your monoid works with the result should be that element.
IsEq<A>	MonoidLaws.monoidRightIdentity(A x)	If an element of the type your monoid works with is combined with the zero of your monoid result should be that element.
IsEq<A>	SemigroupLaws.multiply1pEqualRepeatedAppend(int n, A a)	The Semigroup.multiply1p(int, Object) function of your semigroup must be equal to Semigroup.sumNonEmpty(Object, Iterable) applied to the input and an iterable containing n - 1 copies of that input
IsEq<A>	MonoidLaws.multiplyEqualRepeatedAppend(int n, A a)	The multiply function of your monoid must be equal to the sum function called with an iterable containing n copies of the input type.

IsEq<A>	MonoidLaws.sumEqualFold(java.lang.Iterable<A> as)	The sum function of your monoid must be equal to Functions.fold(BiFunction, Object, Iterable) using append as the folding function and zero() as the initial value
IsEq<A>	SemigroupLaws.sumNonEmptyEqualFold(A head, java.lang.Iterable<A> tail)	The Semigroup.sumNonEmpty(Object, Iterable) function of your semigroup must be equal to a Functions.fold(BiFunction, Object, Iterable) where append is used as the combining function, head is used as the initial value and tail is the iterable to check
