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.

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) -
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.

trait
ColumnType[T] extends Serializable
Serializable representation of column data type.

NullableTypeConverter[T] extends TypeConverter[T]
Handles nullable types and converts any null to null.

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.

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. -
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 offield
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 extendsFieldDef
-
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
.

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.
