public static <C extends Comparable> ImmutableRangeSet<C> of()
Returns an empty immutable range set.
public static <C extends Comparable> ImmutableRangeSet<C> of(Range<C> range)
Returns an immutable range set containing the specified single range. If range.isEmpty(), this is equivalent to of().
public static <C extends Comparable> ImmutableRangeSet<C> copyOf(RangeSet<C> rangeSet)
Returns an immutable copy of the specified RangeSet.
public boolean encloses(Range<C> otherRange)
RangeSetReturns true if there exists a member range in this range set which encloses the specified range.
encloses in interface RangeSet<C extends Comparable>public Range<C> rangeContaining(C value)
RangeSetReturns the unique range from this range set that contains value, or null if this range set does not contain value.
rangeContaining in interface RangeSet<C extends Comparable>public Range<C> span()
RangeSetReturns the minimal range which encloses all ranges in this range set.
span in interface RangeSet<C extends Comparable>public boolean isEmpty()
RangeSetReturns true if this range set contains no ranges.
isEmpty in interface RangeSet<C extends Comparable>public void add(Range<C> range)
RangeSetAdds the specified range to this RangeSet (optional operation). That is, for equal range sets a and b, the result of a.add(range) is that a will be the minimal range set for which both a.enclosesAll(b) and a.encloses(range).
Note that range will be coalesced with any ranges in the range set that are connected with it. Moreover, if range is empty, this is a no-op.
add in interface RangeSet<C extends Comparable>public void addAll(RangeSet<C> other)
RangeSetAdds all of the ranges from the specified range set to this range set (optional operation). After this operation, this range set is the minimal range set that encloses both the original range set and other.
This is equivalent to calling RangeSet.add(com.diffplug.common.collect.Range<C>) on each of the ranges in other in turn.
addAll in interface RangeSet<C extends Comparable>public void remove(Range<C> range)
RangeSetRemoves the specified range from this RangeSet (optional operation). After this operation, if range.contains(c), this.contains(c) will return false.
If range is empty, this is a no-op.
remove in interface RangeSet<C extends Comparable>public void removeAll(RangeSet<C> other)
RangeSetRemoves all of the ranges from the specified range set from this range set (optional operation). After this operation, if other.contains(c), this.contains(c) will return false.
This is equivalent to calling RangeSet.remove(com.diffplug.common.collect.Range<C>) on each of the ranges in other in turn.
removeAll in interface RangeSet<C extends Comparable>public ImmutableSet<Range<C>> asRanges()
RangeSetReturns a view of the disconnected ranges that make up this range set. The returned set may be empty. The iterators returned by its Iterable.iterator() method return the ranges in increasing order of lower bound (equivalently, of upper bound).
asRanges in interface RangeSet<C extends Comparable>public ImmutableSet<Range<C>> asDescendingSetOfRanges()
RangeSetReturns a descending view of the disconnected ranges that make up this range set. The returned set may be empty. The iterators returned by its Iterable.iterator() method return the ranges in decreasing order of lower bound (equivalently, of upper bound).
asDescendingSetOfRanges in interface RangeSet<C extends Comparable>public ImmutableRangeSet<C> complement()
RangeSetReturns a view of the complement of this RangeSet.
The returned view supports the RangeSet.add(com.diffplug.common.collect.Range<C>) operation if this RangeSet supports RangeSet.remove(com.diffplug.common.collect.Range<C>), and vice versa.
complement in interface RangeSet<C extends Comparable>public ImmutableRangeSet<C> subRangeSet(Range<C> range)
Returns a view of the intersection of this range set with the given range.
subRangeSet in interface RangeSet<C extends Comparable>public ImmutableSortedSet<C> asSet(DiscreteDomain<C> domain)
Returns an ImmutableSortedSet containing the same values in the given domain contained by this range set.
Note: a.asSet(d).equals(b.asSet(d)) does not imply a.equals(b)! For example, a and b could be [2..4] and (1..5), or the empty ranges [3..3) and [4..4).
Warning: Be extremely careful what you do with the asSet view of a large range set (such as ImmutableRangeSet.of(Range.greaterThan(0))). Certain operations on such a set can be performed efficiently, but others (such as Set.hashCode() or Collections.frequency(java.util.Collection<?>, java.lang.Object)) can cause major performance problems.
The returned set’s Object.toString() method returns a short-hand form of the set’s contents, such as "[1..100]"}.
IllegalArgumentException - if neither this range nor the domain has a lower bound, or if  neither has an upper boundpublic static <C extends Comparable<?>> ImmutableRangeSet.Builder<C> builder()
Returns a new builder for an immutable range set.
public boolean contains(C value)
RangeSetDetermines whether any of this range set’s member ranges contains value.
contains in interface RangeSet<C extends Comparable>public void clear()
RangeSetRemoves all ranges from this RangeSet (optional operation). After this operation, this.contains(c) will return false for all c.
This is equivalent to remove(Range.all()).
clear in interface RangeSet<C extends Comparable>public boolean enclosesAll(RangeSet<C> other)
RangeSetReturns true if for each member range in other there exists a member range in this range set which encloses it. It follows that this.contains(value) whenever other.contains(value). Returns true if other is empty.
This is equivalent to checking if this range set RangeSet.encloses(com.diffplug.common.collect.Range<C>) each of the ranges in other.
enclosesAll in interface RangeSet<C extends Comparable>public boolean equals(@Nullable Object obj)
RangeSetReturns true if obj is another RangeSet that contains the same ranges according to Range.equals(Object).
public final int hashCode()
RangeSetReturns asRanges().hashCode().
