Alias (Querydsl 4.1.4 API)

java.lang.Object
- com.querydsl.core.alias.Alias

public final class Alias
extends Object

Alias provides alias factory methods

Example:


 Employee e = alias(Employee.class, "e");
 for (String name : query.from($(e),employees)
     .where($(e.getDepartment().getId()).eq(1001))
     .list($(e.getName()))) {
     System.out.println(name);
 }

using the following static imports


 import static com.mysema.query.alias.Alias.$;
 import static com.mysema.query.alias.Alias.alias;
