Interface Serializer<T>

Type Parameters:

T - The type to which data extraction should work.

All Known Implementing Classes:

AbstractSerializer, AnnotatedCompositeSerializer, AsciiSerializer, BigDecimalSerializer, BigIntegerSerializer, BooleanSerializer, ByteBufferSerializer, BytesArraySerializer, ByteSerializer, CharSerializer, CompositeSerializer, DateSerializer, DoubleSerializer, DynamicCompositeSerializer, FloatSerializer, GzipStringSerializer, Int32Serializer, IntegerSerializer, JaxbSerializer, ListSerializer, LongSerializer, MapSerializer, ObjectSerializer, PrefixedSerializer, SetSerializer, ShortSerializer, SnappyStringSerializer, SpecificCompositeSerializer, StringSerializer, TimeUUIDSerializer, TypeInferringSerializer, UUIDSerializer

public interface Serializer<T>

Serializes a type T from the given bytes, or vice a versa. In cassandra column names and column values (and starting with 0.7.0 row keys) are all byte[]. To allow type safe conversion in java and keep all conversion code in one place we define the Extractor interface. Implementors of the interface define type conversion according to their domains. A predefined set of common extractors can be found in the extractors package, for example StringSerializer.
