SetUtil class

Set algebra helpers ?union / intersection / difference / symmetric difference ?plus a few convenient constructors that preserve order via LinkedHashSet.

Static Methods

difference<T>(Set<T> a, Set<T> b) → Set<T>

a minus b ?elements in a that are not in b.

from<T>(Iterable<T> source) → Set<T>

Build a LinkedHashSet from source, preserving iteration order.

fromMap<T, R>(Iterable<T> source, R transform(T)) → Set<R>

Build a LinkedHashSet from source, applying transform to each element first.

intersection<T>(Set<T> a, Set<T> b) → Set<T>

Intersection of a and b ?elements present in both sets.

removeWhere<T>(Set<T> source, bool test(T)) → int

Remove source elements that satisfy test. Returns the removed count.

symmetricDifference<T>(Set<T> a, Set<T> b) → Set<T>

Symmetric difference ?elements in either a or b but not both.

union<T>(Set<T> a, Set<T> b) → Set<T>

Union of a and b ?every element present in either set.
