Entity | PHP package for Entity-Builder and Laravel Code Generator | Build Tool library

I am using class based projection with constructor expressions. here is a sample code form my work

I have a for loop which calls a few times to database API. These calls return data for a menu, but when I try to map array I can't do it because array is empty.

First scenario:

I have two tables:

1. Car_company which has the attributes of: C_id (primary key), C_name
2. Car_model which has the attributes of: Com_id (referenced to C_id of Car_company), Model_year Warranty

I wish to access both of these tables individually and also I would like to perform a join operation on them and display all of the car_models along with their car_company name. I tried using both JPQL and native query but nothing worked. I also made sure to use the OneToMany and ManyToOne associations but I ended up getting infinite nesting,i.e, the models have car_company as field, this inturn has car_models as a list, and this keeps going. Please help me with entity classes and DAOs.

I am currently trying to write some ECS in C++. Inside my ECS (Entity component system), I have a set of entities which all have a set of components. Like a position, rotation, etc.. What I want to do is implement a function which returns an iterator to iterate over the entities which fullfill a few requirements. These requirements are grouped into the following categories:

1. required
2. requires_one
3. excludes

Ideally, I would call the function like this:
