Abstract Value Members

  1. abstract def columnName: String

    Returns the column name which this selection bases on.

    Returns the column name which this selection bases on. In case of a function, such as ttl or writetime, it returns the column name passed to that function.

  2. abstract def cql: String

    Returns a CQL phrase which has to be passed to the SELECT clause with appropriate quotation marks.

    Returns a CQL phrase which has to be passed to the SELECT clause with appropriate quotation marks.

  3. abstract def selectedAs: String

    Returns the name of the column to be used by the user in the RDD item object.

    Returns the name of the column to be used by the user in the RDD item object. If the column is selected into a CassandraRow, this name should be used to get the column value. Also this name will be matched to an object property by column mappers

    SelectableColumnRef

  4. abstract def selectedFromCassandraAs: String

    Returns a name of the selection as it is seen in the result set.

    Returns a name of the selection as it is seen in the result set. Most likely this is going to be used when providing custom column name to field name mapping.
