org.lenskit.data.entities.TypedName<T>

All Implemented Interfaces:

Serializable

@Immutable
public final class TypedName<T>
extends Object
implements Serializable

An association of a type with a name. This is used for type-safe (or at least type-suggested) access to entity attributes, and allows declarations of attribute names to also contain the type of data that will be stored in the specified attribute.

When used consistently, they allow for type-safe access to entity attribute data.
