Abstract Value Members

  1. abstract def neededColumns: Option[Seq[ColumnRef]]

    List of columns this RowReader is going to read.

    List of columns this RowReader is going to read. Useful to avoid fetching the columns that are not needed.

  2. abstract def read(row: Row, rowMetaData: CassandraRowMetadata): T

    Reads column values from low-level Row and turns them into higher level representation.

    Reads column values from low-level Row and turns them into higher level representation.

    row

    row fetched from Cassandra

    rowMetaData

    column names and codec available in the row
