Class TreeRangeSet<C extends Comparable<?>>

    • Method Detail

      • create

        public static <C extends Comparable<?>> TreeRangeSet<C> create​(Iterable<Range<C>> ranges)
        Returns a TreeRangeSet representing the union of the specified ranges.

        This is the smallest RangeSet which encloses each of the specified ranges. An element will be contained in this RangeSet if and only if it is contained in at least one Range in ranges.

        21.0
      • intersects

        public boolean intersects​(Range<C> range)
        Description copied from interface: RangeSet
        Returns true if there exists a non-empty range enclosed by both a member range in this range set and the specified range. This is equivalent to calling subRangeSet(otherRange) and testing whether the resulting range set is non-empty.
        Specified by:
        intersects in interface RangeSet<C extends Comparable<?>>
      • add

        public void add​(Range<C> rangeToAdd)
        Description copied from interface: 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.

      • remove

        public void remove​(Range<C> rangeToRemove)
        Description copied from interface: 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.

      • contains

        public boolean contains​(C value)
        Description copied from interface: RangeSet
        Determines whether any of this range set's member ranges contains value.
        Specified by:
        contains in interface RangeSet<C extends Comparable>
      • isEmpty

        public boolean isEmpty()
        Description copied from interface: RangeSet
        Returns true if this range set contains no ranges.
        Specified by:
        isEmpty in interface RangeSet<C extends Comparable>
      • clear

        public void clear()
        Description copied from interface: 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>
      • addAll

        public void addAll​(RangeSet<C> other)
        Description copied from interface: 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.google.common.collect.Range<C>) on each of the ranges in other in turn.

        addAll in interface RangeSet<C extends Comparable>
      • removeAll

        public void removeAll​(RangeSet<C> other)
        Description copied from interface: 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.google.common.collect.Range<C>) on each of the ranges in other in turn.

      • equals

        public boolean equals​(@CheckForNull
                              Object obj)
        Description copied from class: java.lang.Object
        Indicates whether some other object is "equal to" this one.

        The equals method implements an equivalence relation on non-null object references:

        • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
        • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
        • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
        • It is consistent: for any non-null reference values 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.
        • For any non-null reference value 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.

        Specified by:
        equals in interface RangeSet<C extends Comparable>
        Overrides:
        equals in class Object
        Parameters:
        obj - the reference object with which to compare.
        Returns:
        true if this object is the same as the obj argument; false otherwise.

      • hashCode

        public final int hashCode()
        Description copied from class: java.lang.Object
        Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

        The general contract of hashCode is:

        • Whenever it is invoked on the same object more than once during an execution of a Java application, the 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.
        • If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
        • It is not required that if two objects are unequal according to the 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. (The hashCode may or may not be implemented as some function of an object's memory address at some point in time.)

        Specified by:
        hashCode in interface RangeSet<C extends Comparable>
        Overrides:
        hashCode in class Object
        Returns:
        a hash code value for this object.

      • toString

        public final String toString()
        Description copied from class: java.lang.Object
        Returns a string representation of the object. In general, the toString 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())

        toString in interface RangeSet<C extends Comparable>
        Overrides:
        toString in class Object
        Returns:
        a string representation of the object.
