How to use the filter / sort operation for Entity classes having @EmbeddedId composite key

[ParthaNath28]

Hello

As discussed in the Gitter Channel I would like to know the syntax to be used while working entity classes having @EmbeddedId composite key based objects.

jpaStreamer.stream(MyOwnEntity.class)
.filter(MyOwnEntity$.<do I put property of nested composite key object ?>.equalIgnoreCase("filterIdentifier"))

@embeddable
public class EmployeeId implements Serializable {

@Column(name = "company_id")
private Long companyId;

@Column(name = "employee_number")
private Long employeeNumber;

}

@entity(name = "Employee")
@table(name = "employee")
public class EmployeeEntity {

@EmbeddedId
private EmployeeId id;

private String name;

}

There can be scenario that distinct employees might not be identified by their employee id but a composite id needs be used with a combination of employee id and company id. However I might
functionality to find all employees having employee number 12345. Had it been a linear Entity class structure the jpaStreamer code might have looked liked the following.

final List employeeList=
jpaStreamer.stream(EmployeeEntity.class)
.filter(EmployeeEntity$.employeeNumber.equalIgnoreCase())
.toList();
