Methods

clear() → void

Clears the combinations cache.

getCombinations(Set<T> alphabet, int minimumSize, int maximumSize) → List<List<E>>

Returns a cached combination or generates it.

getCombinationsShared(Set<T> alphabet, int minimumSize, int maximumSize) → List<List<E>>

Same of getCombinations, but the returned List won't be isolated from the cache (is the actual instance inside the cache).

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.
