Class EnumArrayStringConverter

org.neo4j.ogm.typeconversion.EnumArrayStringConverter

All Implemented Interfaces:

AttributeConverter<Enum[],String[]>

public class EnumArrayStringConverter
extends Object
implements AttributeConverter<Enum[],String[]>

By default the OGM will map enum arrays to and from the string arrays with values 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 of the enum constants.
