Class EnumStringConverter

java.lang.Object

org.neo4j.ogm.typeconversion.EnumStringConverter

All Implemented Interfaces:

AttributeConverter<Enum,String>

public class EnumStringConverter
extends Object
implements AttributeConverter<Enum,String>

By default the OGM will map enum objects to and from the string value returned by enum.name() enum.name() is preferred to enum.ordinal() because it is (slightly) safer: a persisted enum have to be renamed to break its database mapping, whereas if its ordinal was persisted instead, the mapping would be broken simply by changing the declaration order in the enum set.
