Method Details
- getOrderedKeysIterator
  
  public OrderedKeys.Iterator getOrderedKeysIterator()
  
  Description copied from interface: OrderedKeys
  
  Get an OrderedKeys.Iterator over this OrderedKeys.
  
  Specified by:
  
  getOrderedKeysIterator in interface OrderedKeys
  
  Returns:
  
  A new iterator, positioned at the first key
- getOrderedKeysByPosition
  
  public OrderedKeys getOrderedKeysByPosition(long startPositionInclusive, long length)
  
  Description copied from interface: OrderedKeys
  
  Get an ordered subset of the keys in this OrderedKeys for a position range. The result will contain the set of keys in this that lie at positions in the half-open range [startPositionInclusive, startPositionInclusive + length). The returned reference is owned by the caller, who should call close() when it is done with it.
  
  Specified by:
  
  getOrderedKeysByPosition in interface OrderedKeys
  
  Parameters:
  
  startPositionInclusive - The position of the first key to include
  
  length - The number of keys to include
  
  Returns:
  
  The subset as an OrderedKeys, which may be this
- getOrderedKeysByKeyRange
  
  public OrderedKeys getOrderedKeysByKeyRange(long startKeyInclusive, long endKeyInclusive)
  
  Description copied from interface: OrderedKeys
  
  Get an ordered subset of the keys in this OrderedKeys for a key range. The returned set will be the intersection of the keys in this with the keys in the closed interval [startKeyInclusive, endKeyInclusive]. The returned reference is owned by the caller, who should call close() when it is done with it.
  
  Specified by:
  
  getOrderedKeysByKeyRange in interface OrderedKeys
  
  Parameters:
  
  startKeyInclusive - The minimum key to include
  
  endKeyInclusive - The maximum key to include
  
  Returns:
  
  The subset as an OrderedKeys, which may be this
- asIndex
  
  public Index asIndex()
  
  Description copied from interface: OrderedKeys
  
  Get an Index representation of this OrderedKeys.
  
  Specified by:
  
  asIndex in interface OrderedKeys
  
  Returns:
  
  An Index representation for the same keys in the same order
- asKeyIndicesChunk
  
  public LongChunk<Attributes.OrderedKeyIndices> asKeyIndicesChunk()
  
  Description copied from interface: OrderedKeys
  
  Get a LongChunk representation of the individual keys in this OrderedKeys.
  
  Specified by:
  
  asKeyIndicesChunk in interface OrderedKeys
  
  Returns:
  
  A LongChunk containing the keys in this OrderedKeys
- asKeyRangesChunk
  
  public LongChunk<Attributes.OrderedKeyRanges> asKeyRangesChunk()
  
  Description copied from interface: OrderedKeys
  
  Get a LongChunk representation of key ranges in this OrderedKeys.
  
  Specified by:
  
  asKeyRangesChunk in interface OrderedKeys
  
  Returns:
  
  A LongChunk containing the key ranges in this OrderedKeys
- fillKeyIndicesChunk
  
  public void fillKeyIndicesChunk(WritableLongChunk<? extends Attributes.KeyIndices> chunkToFill)
  
  Description copied from interface: OrderedKeys
  
  Fill the supplied WritableLongChunk with individual keys from this OrderedKeys.
  The chunk's capacity is assumed to be big enough.
  
  Specified by:
  
  fillKeyIndicesChunk in interface OrderedKeys
  
  Parameters:
  
  chunkToFill - A chunk to fill with individual keys
- fillKeyRangesChunk
  
  public void fillKeyRangesChunk(WritableLongChunk<Attributes.OrderedKeyRanges> chunkToFill)
  
  Description copied from interface: OrderedKeys
  
  Fill the supplied WritableLongChunk with key ranges from this OrderedKeys.
  The chunk's capacity is assumed to be big enough.
  
  Specified by:
  
  fillKeyRangesChunk in interface OrderedKeys
  
  Parameters:
  
  chunkToFill - A chunk to fill with key ranges
- isEmpty
  
  public boolean isEmpty()
  
  Description copied from interface: OrderedKeys
  
  True if the size of this Orderedkeys is zero.

  Get the last key in this OrderedKeys.
  
  Specified by:
  
  lastKey in interface OrderedKeys
  
  Returns:
  
  The last key, or ReadOnlyIndex.NULL_KEY if there is none.
- size
  
  public long size()
  
  Description copied from interface: OrderedKeys
  
  Get the number of keys in this OrderedKeys.

- getAverageRunLengthEstimate
  
  public long getAverageRunLengthEstimate()
  
  Description copied from interface: OrderedKeys
  
  Get an estimate of the average (mean) length of runs of adjacent keys in this OrderedKeys.
  Implementations should strive to keep this method efficient (O(1) preferred) at the expense of accuracy.
  Empty OrderedKeys should return an arbitrary valid value, usually 1.
  
  Specified by:
  
  getAverageRunLengthEstimate in interface OrderedKeys
  
  Returns:
  
  An estimate of the average run length in this OrderedKeys, in [1, size()]
- forEachLong
  
  public boolean forEachLong(LongAbortableConsumer lc)

  For as long as the consumer wants more keys, call accept on the consumer with the individual key instances in this OrderedKeys, in increasing order.
  
  Specified by:
  
  forEachLong in interface OrderedKeys
  
  Parameters:
  
  lc - a consumer to feed the individual key values to.
  
  Returns:
  
  false if the consumer provided ever returned false, true otherwise.
- forEachLongRange
  
  public boolean forEachLongRange(LongRangeAbortableConsumer lrac)
  
  Description copied from interface: OrderedKeys
  
  For as long as the consumer wants more ranges, call accept on the consumer with the individual key ranges in this OrderedKeys, in increasing order.
  
  Specified by:
  
  forEachLongRange in interface OrderedKeys
  
  Parameters:
  
  lrac - a consumer to feed the individual key values to.
  
  Returns:
  
  false if the consumer provided ever returned false, true otherwise.
- close
  
  public void close()
  
  Description copied from interface: OrderedKeys
  
  Free any resources associated with this object.
  Using any OrderedKeys methods after close() is an error and may produce exceptions or undefined results.
  
  Specified by:
  
  close in interface AutoCloseable
  
  Specified by:
  
  close in interface OrderedKeys
  
  Specified by:
  
  close in interface SafeCloseable
