Interface Expressions.Joiner<T>

Enclosing class:
Expressions
public static interface Expressions.Joiner<T>
Strategy interface used by Expressions.join(From, PropertyReference) to obtain joins using property references.

Implementations adapt a From and expose typed join methods for singular and collection-valued attributes as well as map-valued attributes. The methods accept PropertyReference instances to avoid string-based attribute navigation.
