package types

Offers type conversion magic, so you can receive Cassandra column values in a form you like the most. Simply specify the type you want to use on the Scala side, and the column value will be converted automatically. Works also with complex objects like collections.

Type Members

  1. trait CanBuildFrom[-Elem, To] extends Serializable

    Serves the same purpose as standard Scala CanBuildFrom, however this one is Serializable.

  2. sealed trait CassandraOption[+A] extends Product with Serializable

    An Optional value with Cassandra in mind.

    An Optional value with Cassandra in mind. There are three options Value(value): Representing a value to be inserted from C* Unset: Representing a value which should be skipped when writing to C* Null: Representing a java null, treated as a delete in C* (or empty collection)

  3. class ChainedTypeConverter[T] extends NullableTypeConverter[T]

    Chains together several converters converting to the same type.

    Chains together several converters converting to the same type. This way you can extend functionality of any converter to support new input types.

  4. trait CollectionColumnType[T] extends ColumnType[T]
  5. trait ColumnType[T] extends Serializable

    Serializable representation of column data type.

  6. case class ListType[T](elemType: ColumnType[T], isFrozen: Boolean = false) extends CollectionColumnType[Vector[T]] with Product with Serializable
  7. case class MapType[K, V](keyType: ColumnType[K], valueType: ColumnType[V], isFrozen: Boolean = false) extends CollectionColumnType[Map[K, V]] with Product with Serializable
  8. trait NullableTypeConverter[T] extends TypeConverter[T]

    Handles nullable types and converts any null to null.

  9. trait PrimitiveColumnType[T] extends ColumnType[T]
  10. case class SetType[T](elemType: ColumnType[T], isFrozen: Boolean = false) extends CollectionColumnType[Set[T]] with Product with Serializable
  11. case class TupleFieldDef(index: Int, columnType: ColumnType[_]) extends FieldDef with Product with Serializable
  12. case class TupleType(componentTypes: TupleFieldDef*) extends StructDef with ColumnType[TupleValue] with Product with Serializable

    A type representing typed tuples.

    A type representing typed tuples. A tuple consists of a sequence of values. Every value is identified by its 0-based position. Every value can be of a different type.

  13. class TypeConversionException extends Exception
  14. trait TypeConverter[T] extends Serializable

    Machinery for converting objects of any type received from Cassandra into objects of Scala types.

    Machinery for converting objects of any type received from Cassandra into objects of Scala types. Every converter knows how to convert object to one type. See TypeConverter companion object for a list of available converters.

  15. case class UDTFieldDef(columnName: String, columnType: ColumnType[_]) extends FieldDef with Product with Serializable

    A Cassandra user defined type field metadata.

    A Cassandra user defined type field metadata. It consists of a name and an associated column type. The word column instead of field is used in member names because we want to treat UDT field entries in the same way as table columns, so that they are mappable to case classes. This is also the reason why this class extends FieldDef

  16. case class UserDefinedType(name: String, columns: IndexedSeq[UDTFieldDef], isFrozen: Boolean = false) extends StructDef with ColumnType[UDTValue] with Product with Serializable

    A Cassandra user defined type metadata.

    A Cassandra user defined type metadata. A UDT consists of a sequence of ordered fields, called columns.

Value Members

  1. def unlazify[T](seq: IndexedSeq[T]): IndexedSeq[T]

    Makes sure the sequence does not contain any lazy transformations.

    Makes sure the sequence does not contain any lazy transformations. This guarantees that if T is Serializable, the collection is Serializable.
