lazy_memo library

Classes

Lazy<T>: A class that caches an object of type T. The cache is populated when the object is first accessed.
LazyList<T>: A lazy variable that caches a list with entries of type T.
LazyMap<K, V>: A lazy variable that caches a map of type Map<K, V>.
LazySet<T>: A lazy variable that caches a set with entries of type T.
MemoizedFunction<A, T>: Class representing a memoized function requiring a single argument of type A and returning an object of type T.
MemoizedFunction2<A1, A2, T>: Class representing a memoized function requiring arguments of type A1 and A2, respectively, and returning an object of type T.

combinations → MemoizedFunction2<BigInt, BigInt, BigInt>: Returns the number of k-combinations of n distinct objects. More formally, let S be a set containing n distinct objects. Then the number of subsets containing k objects is given by combinations(n, k).
final
factorial → MemoizedFunction<BigInt, BigInt>: Returns the factorial of a positive integer. Throws and error of type ArgumentError if a negative argument is provided.
final

DoubleArgumentFunction<A1, A2, T> = T Function(A1 arg1, A2 arg2): A function requiring arguments of type A1, A2 and returning an object of type T.
ObjectFactory<T> = T Function(): Callback used to lazily create an object of type T.
SingleArgumentFunction<A, T> = T Function(A arg): A function requiring a single argument of type A and returning an object of type T.
