subSet

public RangeIntSet subSet(int from,

Description copied from interface: SortedIntSet

Returns a view of the portion of this set whose elements range from fromElement, inclusive, to toElement, exclusive. (If fromElement and toElement are equal, the returned set is empty.) The returned set is backed by this set, so changes in the returned set are reflected in this set, and vice-versa. The returned set supports all optional set operations that this set supports.

The returned set will throw an IllegalArgumentException on an attempt to insert an element outside its range.

Specified by:

subSet in interface SortedIntSet

Parameters:

from - low endpoint (inclusive) of the returned set

to - high endpoint (exclusive) of the returned set

Returns:

a view of the portion of this set whose elements range from fromElement, inclusive, to toElement, exclusive

Specified by:

hashCode

public int hashCode()

Specified by:

hashCode in interface Collection<Integer>

Specified by:

hashCode in interface Set<Integer>

Overrides:

hashCode in class AbstractIntCollection

toString

public String toString()

Overrides:
