Group<T> mixin

A group is a monoid where each element has an inverse.

Superclass constraints

• Monoid<T>

Properties

empty → T

Return the identity element for this monoid.

no setter, inherited

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

combine(T x, T y) → T

Associative operation which combines two values.

inherited

combineN(T a, int n) → T

Return a appended to itself n times. If n is negative, then this returns inverse(a) appended to itself n times.

override

intercalate(T middle) → Semigroup<T>

Return a Semigroup which inserts middle between each pair of elements.

inherited

inverse(T a) → T

Find the inverse of a.

isEmpty(T a, Eq<T> eq) → bool

Tests if a is the identity (empty).

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

remove(T a, T b) → T

Remove the element b from a.

reverse() → Monoid<T>

Return a Monoid that reverses the order.

inherited

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

instance<A>(A emptyValue, A f(A a1, A a2), A inv(A a)) → Group<A>

Create a Group instance from the given function, empty value, and inverse function.
