trait StructDef extends Serializable

Cassandra structure that contains columnar information, e.g. a table or a user defined type. This trait allows ColumnMapper to work on tables and user defined types. Cassandra tables and user defined types are similar in a way data are extracted from them, therefore a common interface to describe their metadata is handy.

Type Members

  1. abstract type Column <: FieldDef

    Permalink

    Allows to specify concrete type of column in subclasses, so that columns and columnByName members return concrete types.

    Allows to specify concrete type of column in subclasses, so that columns and columnByName members return concrete types. Columns in tables may carry more information than columns in user defined types.

  2. abstract type ValueRepr <: AnyRef

    Permalink

    Type of the data described by this struct

Abstract Value Members

  1. abstract val columns: IndexedSeq[Column]

    Permalink

    Sequence of column definitions in this data structure.

    Sequence of column definitions in this data structure. The order of the columns is implementation-defined.

  2. abstract val name: String

    Permalink

    Human-readable name for easy identification of this structure.

    Human-readable name for easy identification of this structure. Used in the error message when the column is not found. E.g. a table name or a type name.

  3. abstract def newInstance(columnValues: Any*): ValueRepr

    Permalink

    Creates new instance of this struct.

    Creates new instance of this struct. Column values must be given in the same order as columnNames
