Class TypeCodec.EnumStringCodec<E extends Enum<E>>

java.lang.Object

com.datastax.driver.core.TypeCodec<T>

com.datastax.driver.core.TypeCodec.StringParsingCodec<E>

com.datastax.driver.core.TypeCodec.EnumStringCodec<E>

Type Parameters:

E - The Enum class this codec serializes from and deserializes to.

Enclosing class:

TypeCodec<T>

public static class TypeCodec.EnumStringCodec<E extends Enum<E>>
extends TypeCodec.StringParsingCodec<E>

A codec that serializes Enum instances as CQL varchars representing their programmatic names as returned by Enum.name().

This codec is automatically used by the driver to create codecs for Enum instances on the fly.
