in this range set.
|
ImmutableRangeSet<C> |
subRangeSet(Range<C> range)
Returns a view of the intersection of this range set with the given range.

RangeSet.public boolean encloses(Range<C> otherRange)

encloses the specified range.encloses in interface RangeSet<C extends Comparable>public Range<C> rangeContaining(C value)
RangeSetvalue, or null if this range set does not contain value.rangeContaining in interface RangeSet<C extends Comparable>public Range<C> span()
RangeSetspan in interface RangeSet<C extends Comparable>public boolean isEmpty()
RangeSettrue if this range set contains no ranges.isEmpty in interface RangeSet<C extends Comparable>public void add(Range<C> range)
RangeSetRangeSet (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)
RangeSetother.
This is equivalent to calling RangeSet.add(com.google.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)
RangeSetRangeSet (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)
RangeSetother.contains(c), this.contains(c) will
return false.
This is equivalent to calling RangeSet.remove(com.google.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()
RangeSetIterable.iterator() method return the ranges in increasing order of lower bound
(equivalently, of upper bound).asRanges in interface RangeSet<C extends Comparable>public ImmutableRangeSet<C> complement()
RangeSetRangeSet.
The returned view supports the RangeSet.add(com.google.common.collect.Range<C>) operation if this RangeSet supports
RangeSet.remove(com.google.common.collect.Range<C>), and vice versa.
complement in interface RangeSet<C extends Comparable>public ImmutableRangeSet<C> subRangeSet(Range<C> range)
subRangeSet in interface RangeSet<C extends Comparable>public ImmutableSortedSet<C> asSet(DiscreteDomain<C> domain)
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]"}.

public boolean contains(C value)
RangeSetvalue.contains in interface RangeSet<C extends Comparable>public void clear()
RangeSetRangeSet (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)
RangeSettrue 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.google.common.collect.Range<C>) each of the ranges in
other.
