kandi X-RAY | reflections Summary
Package reflections provides high level abstractions above the golang reflect library. Reflect library is very low-level and can be quite complex when it comes to do simple things like accessing a structure field value, a field tag…. The purpose of reflections package is to make developers life easier when it comes to introspect structures at runtime. Its API is inspired from python language (getattr, setattr, hasattr…) and provides a simplified access to structure fields and tags. Documentation is available at

QUESTION
I'm trying to make a complete copy of a Snowflake DB into PostgreSQL DB (every table/view, every row). I don't know the best way to go about accomplishing this. I've tried using a package called pipelinewise , but I could not get the access needed to convert a snowflake view to a postgreSQL table (it needs a unique id). Long story short it just would not work for me.
I've now moved on to using the snowflake-sqlalchemy package. So, I'm wondering what is the best way to just make a complete copy of the entire DB. Is it necessary to make a model for each table, because this is a big DB? I'm new to SQL alchemy in general, so I don't know exactly where to start. My guess is with reflections , but when I try the example below I'm not getting any results.

QUESTION
I'm following similar example as in this blog post:
https://rmoff.net/2019/11/12/running-dockerised-kafka-connect-worker-on-gcp/
Except that I'm not running kafka connect worker on GCP but locally.
Everything is fine I run the docker-compose up and kafka connect starts but when I try to create instance of source connector via CURL I get the following ambiguous message (Note: there is literally no log being outputed in the kafka connect logs):
...ANSWER
Answered 2021-Jun-11 at 14:27I managed to get it to work, this is a correct configuration...
The message "Unable to connect to the server" was because I had wrongly deployed mongo instance so it's not related to kafka-connect or confluent cloud.
I'm going to leave this question as an example if somebody struggles with this in the future. It took me a while to figure out how to configure docker-compose for kafka-connect that connects to confluent cloud.
QUESTION
I'm trying to make a simple puzzle system for a game involving beams of light and mirrors in Unity. The light beams are created using an empty GameObject that casts a Raycast2D and uses a LineRenderer to display the beam. When a beam collides with a mirror object I simply use Vector2.Reflect to calculate the new direction.
The implementation works fine when the mirrors are static. When I try to move them around in-game, it causes random stack overflow errors, and there doesn't seem to be a pattern. Here's an example of a working mirror setup:
Here's what happens when I try to move a mirror:
I'm guessing it's due to the mirror somehow reflecting the beam back and causing an infinite reflection loop, but I'm not sure why that would happen.
Relevant code:
...ANSWER
Answered 2021-Jun-09 at 11:15If the condition if(hit.collider.gameObject.tag == "Mirror") is not met, you are doing a lightPoints.Add(hit.point); and upadting the beam, adding points to the LineRenderer component position array also. That does not seem a good idea, as presumably you will get to the point when the ray does not hit anymore. As is, once you get to that point you keep on adding points, leading to the stack overflow.
I would add some safegard condition, where you stop adding points to your lists/arrays if you dont hit a gamobject of interest, maybe a determined ray length, or a condition that avoids the point to be added if the ray does not hit.
I checked the line of the error you are having in the script itself with not very revaling info. But you got the script there in case that helps.
QUESTION
In a maven module with no dependencies to maven module X I am trying to load a class from module X. Is this possible? I cant add a dependency (cycle) and reflection is necessary in my case.
With FilesUtils I can find de files, no issues here. However then I try to run some tests to find out if I can load a class with a path but no results so far.
Both Classloader and URLClassloader get instansiated within my maven module and the following did not work.
...ANSWER
Answered 2021-Jun-07 at 16:33If you have a cyclic dependency, you need to refactor your code. You either need to merge two modules into one or you need to create a common dependency for both modules.
Trying to trick around cyclic dependencies by using classloader or reflection is the wrong approach.
QUESTION
I have two png layers, both with transparent backgrounds, that I'm trying to combine in Imagick in PHP. One is a shape, another is reflections to be applied on top of that shape. However the reflections were drawn overlapping outside the edges of the shape, so I need to clip them to the shape (remove the parts of the reflections that are not inside the shape) when layering it on top, and preserving the alpha channels.
All the examples I can find online do it like this;
...ANSWER
Answered 2021-Jun-04 at 00:27I do not know Imagick well. So here is how to do it in ImageMagick command line. It should be relatively easy to convert the commands to Imagick.
Basically, you separate the alpha channels of the two images and then multiply them together to clip the highlight alpha with the blob alpha. Then you put the result as the new alpha channel back into the highlight image. Then you composite that result as the new highlight image over the blob image.
QUESTION
The ask is to modify the password of a mongodb connection at runtime in a spring boot project. For example let's assume a mongodb connection is established while starting the application with password 'xyz'.I would like to modify the password at runtime by lets say hitting an api. I have tried following solutions so far to tackle this issue:
- Replacing mongoTemplate bean at runtime: Tried creating a new mongoTemplate Bean with new password at runtime and replaced it in the context using the methods given in following link. The issue with this approach is that the bean is getting refreshed only once. Ideally it should work everytime when the api to update password is being called.
- Updating password in mongoCredentials: One of the obvious approach is to update the password directly in mongoCredentials since mongoTemplate uses mongoCredential class to store the credentials information.But the issue is that the password field in MongoCredentials class is 'final static' so we cannot update it even with reflections. Even though there are some tricks to update the final static fields but i'm looking for a more acceptable solution.
ANSWER
Answered 2021-May-30 at 21:19There is @RefreshScope in Spring Cloud project exactly for your purpose. Here is Spring's documentation about how it works: https://cloud.spring.io/spring-cloud-static/spring-cloud.html#_refresh_scope.
So all you need to do is update Environment and call org.springframework.cloud.context.scope.refresh.RefreshScope#refresh or org.springframework.cloud.context.scope.refresh.RefreshScope#refreshAll when you need to refresh your context.

I am trying to send data from Kafka to Elasticsearch. I checked that my Kafka Broker is working because I can see the messages I produce to a topic is read by a Kafka Consumer. However, when I try to connect Kafka to Elasticsearch I get the following error.

...ANSWER
Answered 2021-May-29 at 13:09The Connect container starts Connect Distributed Server already. You should use HTTP and JSON properties to configure the Elastic connector rather than exec into the container shell and issue connect-standalone commands which default to using a broker running in the container itself.
Similarly, the Elastic quickstart file expects Elasticsearch running within the Connect container, by default
QUESTION
I have a record definition where I would like to only check equality on public/specific member variables in the record definition. I haven't found a way to do this without making a custom Equals function and I would prefer not to that if there is another nicer solution. Any reflections on whether private member variables in records is a bad pattern or not, is also appreciated.
Example of record where equality is true:
...ANSWER
Answered 2021-May-23 at 19:33In the microsoft documentation you can read this:
For records, value equality means that two variables of a record type are equal if the types match and all property and field values match. For other reference types such as classes, equality means reference equality. That is, two variables of a class type are equal if they refer to the same object. Methods and operators that determine equality of two record instances use value equality.
The list here needs to have the same reference for the equality to work. I think using an equality comparer or override equal is the best way to go.
QUESTION
I could not find much resources on my question so I guess this is not an easy resolution.
We use JodaTime in our codebase and I wish to forbid (or at least warn) using some methods from this library as they are prone to errors (around timezone management).
I tried the reflections library already, without success due to a non released issue. We used to have a custom sonar rule to handle this but it is not supported by sonarcloud so I looking for another way.
Do you have any lead to handle this?

Answered 2021-May-20 at 07:16I solved such kind of problems by writing an interceptor like the following, as explained at https://docs.oracle.com/javaee/7/tutorial/interceptors002.htm:
