Constructor Detail

AbstractBounds

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

Method Detail

serializer

public static AbstractBounds.AbstractBoundsSerializer serializer()

split

public Pair<AbstractBounds,AbstractBounds> split(Token token)

Given token T and AbstractBounds ?L,R], returns Pair(?L,T], ?T,R]) (where ? means that the same type of Bounds is returned -- Range or Bounds -- as the original.) The original AbstractBounds must contain the token T. If the split would cause one of the left or right side to be empty, it will be null in the result pair.

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public abstract boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

contains

public abstract boolean contains(Token start)

createFrom

public abstract AbstractBounds createFrom(Token right)

Returns:

A clone of this AbstractBounds with a new right Token, or null if an identical range would be created.

unwrap

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

normalize

public static java.util.List<AbstractBounds> normalize(java.util.Collection<? extends AbstractBounds> bounds)

Returns:

A copy of the given list of with all bounds unwrapped, sorted by bound.left and with overlapping bounds merged. This method does not allow allow to mix Range and Bound in the input list.
