Enclosing class:

DataType

public static class DataType.CustomType
extends DataType

A "custom" type is a type that cannot be expressed as a CQL type.

Each custom type is merely identified by the fully qualified #getCustomTypeClassName() class name that represents this type server-side.

The driver provides a minimal support for such types through instances of this class.

A codec for custom types can be obtained via TypeCodec.custom(DataType.CustomType).
