kandi X-RAY | root Summary

root is a C++ library. root has no bugs, it has no vulnerabilities and it has medium support. However root has a Non-SPDX License. You can download it from GitHub.

The ROOT system provides a set of OO frameworks with all the functionality needed to handle and analyze large amounts of data in a very efficient way. Having the data defined as a set of objects, specialized storage methods are used to get direct access to the separate attributes of the selected objects, without having to touch the bulk of the data. Included are histograming methods in an arbitrary number of dimensions, curve fitting, function evaluation, minimization, graphics and visualization classes to allow the easy setup of an analysis system that can query and process the data interactively or in batch mode, as well as a general parallel processing framework, PROOF, that can considerably speed up an analysis. Thanks to the built-in C++ interpreter cling, the command, the scripting and the programming language are all C++. The interpreter allows for fast prototyping of the macros since it removes the time consuming compile/link cycle. It also provides a good environment to learn C++. If more performance is needed the interactively developed macros can be compiled using a C++ compiler via a machine independent transparent compiler interface called ACliC. The system has been designed in such a way that it can query its databases in parallel on clusters of workstations or many-core machines. ROOT is an open system that can be dynamically extended by linking external libraries. This makes ROOT a premier platform on which to build data acquisition, simulation and data analysis systems.

Both Swing and JavaFX are single-threaded UI toolkits, and each has their own thread for rendering the UI and processing user events. Modifying Swing components and creating Swing windows (e.g. JFrames) must be done on the AWT event dispatch thread. Modifying JavaFX components must be done on the FX Application Thread.

Thus when you're working with both toolkits together, you have to be careful to delegate the appropriate actions to the appropriate threads. The Javadocs for JFXPanel have more details.

Here's a complete example which includes a slight re-working of your code and shows how to move the different parts of the code to the appropriate thread:

React Router Link changes URL but doesn't render Component - Rest Countries API

Asked 2021-Jun-15 at 17:07

I am building an app following the Rest Countries API challenge from frontendmentor (https://www.frontendmentor.io/challenges/rest-countries-api-with-color-theme-switcher-5cacc469fec04111f7b848ca). I have run into a problem. When clicking on the router link in countryDetail.js, the url changes but the component doesn't get re-rendered unless the page is refreshed.

CountryDetails.js

...

ANSWER

Answered 2021-Jun-15 at 17:07

Issue

The issue seems to be that you are already on the "/country/:name" path and are clicking to visit another country. The router correctly updates the URL in the address bar, but because CountryDetail is already mounted it neglects to recompute the item and allCountries state. This is because the useEffect hook only runs once when the component mounts.

Solution

The name param (match.params.name) is actually a dependency for the GET requests, it should be added to the useEffect hook's dependency array.
