## org.apache.cassandra.dht
Class AbstractBounds

    java.lang.Object
      org.apache.cassandra.dht.AbstractBounds

All Implemented Interfaces:
  java.io.Serializable

Direct Known Subclasses:
  Bounds, Range

    public abstract class AbstractBounds

extends java.lang.Object
implements java.io.Serializable

  Serialized Form

Field Summary
`Token` `left`
`protected IPartitioner` `partitioner`
`Token` `right`

Constructor Summary
`AbstractBounds(Token left, Token right, IPartitioner partitioner)`

Method Summary
`abstract boolean` `contains(Token start)`
`abstract AbstractBounds` `createFrom(Token right)`
`abstract boolean` `equals(java.lang.Object obj)`
`int` `hashCode()`
`static ICompactSerializer2<AbstractBounds>` `serializer()`
`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.

Field Detail

### left

    public final Token left

### right

    public final Token right

### partitioner

    protected final transient IPartitioner partitioner

Constructor Detail

### AbstractBounds

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

Method Detail

### serializer

    public static ICompactSerializer2<AbstractBounds> 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 R==T, null is returned as the right element of the 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.
