How to have a class with an instance of its predecessor and continue its heirarchy for all new instances?

By -

I'll try to be as specific as possible so it's easy to understand.

Let's say you have a class that holds a rectangle in the form of (x, y, w, h) when working on a 2d plane with (0,0) being the top left of the display. The first instance of this class holds the values (0,0,1920,1080), which sets the display dimensions for a program.

Now, from here, I want to have all the next instances of Rectangle to exist within the previous one, such that their coordinates act as relative positions to it.

For example, let's work with the next 2 Rectangle instances. I'll declare one called rect1 to have the values (100,100,500,500), and then the second instance called rect2 to exist within rect1. Its values will be (50,50,50,50).

Now, I want the heirarchy of values to apply to all instances to allow the relative positioning. What this would mean is that (relative to the original display's rectangle's first instance), rect1 will have a relative position in the form (x,y) of (100,100), however rect2 will have a relative position of (150,150) TO THE ORIGINAL DISPLAY'S RECTANGLE's FIRST INSTANCE.

But, to make life easy and follow the heirarchy, rect2 will have a RELATIVE POSITION TO rect1 of (50,50), yet in terms of the predasessor of rect1, its relative position is (150,150), as explained before.

Here is a picture of what I am trying to demonstrate:

So, with that type of structure in mind, how would I be able to translate that concept into code that follows the same idea?

Hibernate Search - Elasticsearch with JSON manipulation

By -
Elasticsearch with JSON manipulation Elasticsearch ships with many features. It is possible that at some point, one feature you need will not be exposed by the Search DSL. To work around such limitations, Hibernate Search provides ways to: Transform the HTTP request sent to Elasticsearch for search queries. Read the raw JSON of the HTTP response received from Elasticsearch for search queries. Direct changes to the HTTP request may conflict with Hibernate Search features and be supported differently by different versions of Elasticsearch. Similarly, the content of the HTTP response may change depending on the version of Elasticsearch, depending on which Hibernate Search features are used, and even depending on how Hibernate Search features are implemented. Thus, features relying on direct access to HTTP requests or responses cannot be guaranteed to continue to work when upgrading Hibernate Search, even for micro upgrades (x.y.z to x.y.(z+1)). Use this at your own risk....

Spring Elasticsearch Operations

By -
Elasticsearch Operations Spring Data Elasticsearch uses two interfaces to define the operations that can be called against an Elasticsearch index. These are ElasticsearchOperations and ReactiveElasticsearchOperations. Whereas the first is used with the classic synchronous implementations, the second one uses reactive infrastructure. The default implementations of the interfaces offer: Read/Write mapping support for domain types. A rich query and criteria api. Resource management and Exception translation. ElasticsearchTemplate The ElasticsearchTemplate is an implementation of the ElasticsearchOperations interface using the Transport Client. @Configuration public class TransportClientConfig extends ElasticsearchConfigurationSupport {   @Bean   public Client elasticsearchClient() throws UnknownHostException {                      Settings settings = Settings.builder().put("cluster.name", "elasticsearch")....
