All Implemented Interfaces:

ValueSet

public class EquatableValueSet
extends Object
implements ValueSet

A set containing values that are uniquely identifiable. Assumes an infinite number of possible values. The values may be collectively included or collectively excluded.

tryExpandRanges

public Optional<Collection<Object>> tryExpandRanges(int valuesLimit)

Description copied from interface: ValueSet

Try to expand valueSet into a discrete set of (at most limit) objects. For example: [1, 5] can be expanded into {1, 2, 3, 4, 5}. If the data type is not supported or the expansion results in too many values, Optional.empty() is returned.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
