Examples of com.netflix.astyanax.Serializer

com.netflix.astyanax.Serializer
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 {@link StringSerializer}. @author Ran Tavory @param < T> The type to which data extraction should work.
