Type Parameters:

T - expression type

All Implemented Interfaces:

EntityPath<T>, Expression<T>, Path<T>, java.io.Serializable

public final class PathBuilder<T>
extends EntityPathBase<T>

PathBuilder is an extension to EntityPathBase for dynamic path construction

Usage example:

 PathBuilder<User> user = new PathBuilder<User>(User.class, "user");
 Predicate filter = user.getString("firstName").eq("Bob");
 List<User> users = query.from(user).where(filter).list(user);
