Interface ToEnumOrElse<T,E extends Enum<E>>

Type Parameters:

T - the input entity type

E - the enum type

All Superinterfaces:

Comparator<T>, Expression<T>, Function<T,E>, HasCompare<T>, HasCompose<T>, HasHash<T>, HasMap<T,UnaryOperator<E>,ToEnum<T,E>>, NonNullableExpression<T,ToEnumNullable<T,E>>, ToEnum<T,E>

public interface ToEnumOrElse<T,E extends Enum<E>>
extends NonNullableExpression<T,ToEnumNullable<T,E>>, ToEnum<T,E>

Specialized NonNullableExpression for Enum values where a default value is given if the original expression returns null.
