Package org.eclipse.collections.impl.set.immutable

This package contains the implementations of ImmutableSet.

This package contains the following immutable set implementations:

• ImmutableEmptySet - an immutable set with 0 elements.
• ImmutableSingletonSet - an immutable set with 1 element.
• ImmutableDoubletonSet - an immutable set with 2 elements.
• ImmutableTripletonSet - an immutable set with 3 elements.
• ImmutableQuadrupletonSet - an immutable set with 4 elements.
• ImmutableUnifiedSet - the non-modifiable equivalent of UnifiedSet.

This package contains one factory implementation:

• ImmutableSetFactoryImpl - a factory which creates instances of type ImmutableSet.
