public static <C extends Comparable<?>> TreeRangeSet<C> create()
Creates an empty TreeRangeSet
instance.
public static <C extends Comparable<?>> TreeRangeSet<C> create(RangeSet<C> rangeSet)
Returns a TreeRangeSet
initialized with the ranges in the specified range set.
public Set<Range<C>> asRanges()
RangeSet
Returns 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).
public Set<Range<C>> asDescendingSetOfRanges()
RangeSet
Returns 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).
@Nullable public Range<C> rangeContaining(C value)
RangeSet
Returns 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 boolean encloses(Range<C> range)
RangeSet
Returns 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> span()
RangeSet
Returns the minimal range which encloses all ranges in this range set.
public void add(Range<C> rangeToAdd)
RangeSet
Adds 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 remove(Range<C> rangeToRemove)
RangeSet
Removes 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 RangeSet<C> complement()
RangeSet
Returns 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.
public RangeSet<C> subRangeSet(Range<C> view)
RangeSet
Returns a view of the intersection of this RangeSet
with the specified range.
The returned view supports all optional operations supported by this RangeSet
, with the caveat that an IllegalArgumentException
is thrown on an attempt to add any range not enclosed by view
.
public boolean contains(C value)
RangeSet
Determines whether any of this range set’s member ranges contains value
.
contains
in interface RangeSet<C extends Comparable>
public boolean isEmpty()
RangeSet
Returns true
if this range set contains no ranges.
isEmpty
in interface RangeSet<C extends Comparable>
public void clear()
RangeSet
Removes 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)
RangeSet
Returns 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 void addAll(RangeSet<C> other)
RangeSet
Adds 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 removeAll(RangeSet<C> other)
RangeSet
Removes 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 boolean equals(@Nullable Object obj)
RangeSet
Returns true
if obj
is another RangeSet
that contains the same ranges according to Range.equals(Object)
.
public final int hashCode()
RangeSet
Returns asRanges().hashCode()
.
