Class StringToEnumConverter<E extends Enum<E>>

java.lang.Object
com.oorian.data.converter.StringToEnumConverter<E>
Type Parameters:
E - the enum type
All Implemented Interfaces:
Converter<String,E>
public class StringToEnumConverter<E extends Enum<E>> extends Object implements Converter<String,E>
Converts between String and any Enum type.

Conversion to model uses Enum.valueOf(Class, String). Conversion to presentation uses Enum.name(). The comparison is case-sensitive by default; use the case-insensitive constructor for lenient matching.

Usage:


 Converter<String, Status> converter = new StringToEnumConverter<>(Status.class);
 Status value = converter.convertToModel("ACTIVE");    // returns Status.ACTIVE
 String text = converter.convertToPresentation(Status.ACTIVE); // returns "ACTIVE"
