## Class RangeSliceResponseResolver

- java.lang.Object
- - org.apache.cassandra.service.RangeSliceResponseResolver

- All Implemented Interfaces:
    IResponseResolver<RangeSliceReply,java.lang.Iterable<Row>>

      public class RangeSliceResponseResolver
      extends java.lang.Object
      implements IResponseResolver<RangeSliceReply,java.lang.Iterable<Row>>

  Turns RangeSliceReply objects into row (string -> CF) maps, resolving to the most recent ColumnFamily and setting up read repairs as necessary.

    - #### repairResults

          public final java.util.List<AsyncOneResponse> repairResults

  - ### Constructor Detail

    - #### RangeSliceResponseResolver

          public RangeSliceResponseResolver(java.lang.String keyspaceName,
                                            long timestamp)

  - ### Method Detail

    - #### setSources

          public void setSources(java.util.List<java.net.InetAddress> endpoints)

    - #### getData

          public java.util.List<Row> getData()

      Description copied from interface: `IResponseResolver`
      returns the data response without comparing with any digests
      Specified by:
        `getData` in interface `IResponseResolver<RangeSliceReply,java.lang.Iterable<Row>>`

    - #### resolve

          public java.lang.Iterable<Row> resolve()

      Description copied from interface: `IResponseResolver`
      This Method resolves the responses that are passed in . for example : if its write response then all we get is true or false return values which implies if the writes were successful but for reads its more complicated you need to look at the responses and then based on differences schedule repairs . Hence you need to derive a response resolver based on your needs from this interface.
      Specified by:
        `resolve` in interface `IResponseResolver<RangeSliceReply,java.lang.Iterable<Row>>`
