Method Detail

• get

  V get(K key)

  Returns the value associated with the specified key, or null if there is no such value.

  Specifically, if any range in this range map contains the specified key, the value associated with that range is returned.

• getEntry

  Map.Entry<Range<K>,V> getEntry(K key)

  Returns the range containing this key and its associated value, if such a range is present in the range map, or null otherwise.

• span

  Range<K> span()

  Returns the minimal range enclosing the ranges in this RangeMap.

  Throws:

  NoSuchElementException - if this range map is empty

• put

  void put(Range<K> range,
           V value)

  Maps a range to a specified value (optional operation).

  Specifically, after a call to put(range, value), if range.contains(k), then get(k) will return value.

  If range is empty, then this is a no-op.

• putAll

  void putAll(RangeMap<K,V> rangeMap)

  Puts all the associations from rangeMap into this range map (optional operation).

• clear

  void clear()

  Removes all associations from this range map (optional operation).

• remove

  void remove(Range<K> range)

  Removes all associations from this range map in the specified range (optional operation).

  If !range.contains(k), get(k) will return the same result before and after a call to remove(range). If range.contains(k), then after a call to remove(range), get(k) will return null.

• asMapOfRanges

  Map<Range<K>,V> asMapOfRanges()

  Returns a view of this range map as an unmodifiable Map<Range<K>, V>. Modifications to this range map are guaranteed to read through to the returned Map.

  It is guaranteed that no empty ranges will be in the returned Map.

• subRangeMap

  RangeMap<K,V> subRangeMap(Range<K> range)

  Returns a view of the part of this range map that intersects with range.

  For example, if rangeMap had the entries [1, 5] => "foo", (6, 8) => "bar", (10, ‥) => "baz" then rangeMap.subRangeMap(Range.open(3, 12)) would return a range map with the entries (3, 5) => "foo", (6, 8) => "bar", (10, 12) => "baz".

  The returned range map supports all optional operations that this range map supports, except for asMapOfRanges().iterator().remove().

  The returned range map will throw an IllegalArgumentException on an attempt to insert a range not enclosed by range.

• equals

  boolean equals(Object o)

  Returns true if obj is another RangeMap that has an equivalent asMapOfRanges().

• hashCode

  int hashCode()

  Returns asMapOfRanges().hashCode().

• toString

  String toString()

  Returns a readable string representation of this range map.
