Constructor Detail

### RowDigestResolver

    public RowDigestResolver(java.lang.String table,
                             java.nio.ByteBuffer key)

Method Detail

### getData

    public Row getData()
                throws java.io.IOException

  Special case of resolve() so that CL.ONE reads never throw DigestMismatchException in the foreground

  Throws:
    `java.io.IOException`

### resolve

    public Row resolve()
                throws DigestMismatchException,
                       java.io.IOException

  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.

  Throws:
    `DigestMismatchException`
    `java.io.IOException`

### isDataPresent

    public boolean isDataPresent()
