public static <C extends Comparable<?>> TreeRangeSet<C> create()
TreeRangeSet instance.public static <C extends Comparable<?>> TreeRangeSet<C> create(RangeSet<C> rangeSet)
TreeRangeSet initialized with the ranges in the specified range set.public Set<Range<C>> asRanges()
RangeSetIterable.iterator() method return the ranges in increasing order of lower bound
(equivalently, of upper bound).@Nullable 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 boolean encloses(Range<C> range)
RangeSettrue 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()
RangeSetpublic void add(Range<C> rangeToAdd)
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 remove(Range<C> rangeToRemove)
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 RangeSet<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.
public RangeSet<C> subRangeSet(Range<C> view)
RangeSetRangeSet 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)
RangeSetvalue.contains 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 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.
enclosesAll 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 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 boolean equals(@Nullable Object obj)
java.lang.Object
The equals method implements an equivalence relation
on non-null object references:
x, x.equals(x) should return
true.
x and y, x.equals(y)
should return true if and only if
y.equals(x) returns true.
x, y, and z, if
x.equals(y) returns true and
y.equals(z) returns true, then
x.equals(z) should return true.
x and y, multiple invocations of
x.equals(y) consistently return true
or consistently return false, provided no
information used in equals comparisons on the
objects is modified.
x,
x.equals(null) should return false.
The equals method for class Object implements
the most discriminating possible equivalence relation on objects;
that is, for any non-null reference values x and
y, this method returns true if and only
if x and y refer to the same object
(x == y has the value true).
Note that it is generally necessary to override the hashCode
method whenever this method is overridden, so as to maintain the
general contract for the hashCode method, which states
that equal objects must have equal hash codes.

argument; false otherwise.Object.hashCode(),

java.lang.ObjectHashMap.
The general contract of hashCode is:
hashCode method
must consistently return the same integer, provided no information
used in equals comparisons on the object is modified.
This integer need not remain consistent from one execution of an
application to another execution of the same application.
equals(Object)
method, then calling the hashCode method on each of
the two objects must produce the same integer result.
Object.equals(java.lang.Object)
method, then calling the hashCode method on each of the
two objects must produce distinct integer results. However, the
programmer should be aware that producing distinct integer results
for unequal objects may improve the performance of hash tables.
As much as is reasonably practical, the hashCode method defined by
class Object does return distinct integers for distinct
objects. (This is typically implemented by converting the internal
address of the object into an integer, but this implementation
technique is not required by the
JavaTM programming language.)
hashCode in interface RangeSet<C extends Comparable>hashCode in class ObjectObject.equals(java.lang.Object),
System.identityHashCode(java.lang.Object)public final String toString()
java.lang.ObjecttoString method returns a string that
"textually represents" this object. The result should
be a concise but informative representation that is easy for a
person to read.
It is recommended that all subclasses override this method.
The toString method for class Object
returns a string consisting of the name of the class of which the
object is an instance, the at-sign character `@', and
the unsigned hexadecimal representation of the hash code of the
object. In other words, this method returns a string equal to the
value of:
getClass().getName() + '@' + Integer.toHexString(hashCode())
