Field Detail

### left

    public final T extends RingPosition left

### right

    public final T extends RingPosition right

### partitioner

    protected final transient IPartitioner partitioner

Constructor Detail

### AbstractBounds

    public AbstractBounds(T left,
                          T right,
                          IPartitioner partitioner)

Method Detail

### serializer

    public static AbstractBounds.AbstractBoundsSerializer serializer()

### split

    public abstract Pair<AbstractBounds<T>,AbstractBounds<T>> split(T position)

  Given token T and AbstractBounds ?L,R?, returns Pair(?L,T], (T,R?), where ? means that the same type of AbstractBounds is returned as the original. Put another way, returns a Pair of everything this AbstractBounds contains up to and including the split position, and everything it contains after (not including the split position). The original AbstractBounds must either contain the position T, or T should be equals to the left bound L. If the split would only yield the same AbstractBound, null is returned instead.

### hashCode

    public int hashCode()

  Overrides:
    `hashCode` in class `java.lang.Object`

### intersects

    public boolean intersects(java.lang.Iterable<Range<T>> ranges)

  return true if @param range intersects any of the given @param ranges

### contains

    public abstract boolean contains(T start)

### unwrap

    public abstract java.util.List<? extends AbstractBounds<T>> unwrap()

### toRowBounds

    public abstract AbstractBounds<RowPosition> toRowBounds()

  Transform this abstract bounds to equivalent covering bounds of row positions. If this abstract bounds was already an abstractBounds of row positions, this is a noop.

### toTokenBounds

    public abstract AbstractBounds<Token> toTokenBounds()

  Transform this abstract bounds to a token abstract bounds. If this abstract bounds was already an abstractBounds of token, this is a noop, otherwise this use the row position tokens.
