Andrey Kogun opens the meeting, recalling the upcoming conferences (the very closest is Joker 2019 ) and introducing the meeting's speaker, another Andrey.
The report was devoted to the topic of reflection in the Java programming language . The features of reflection calls in the JVM , alternatives to their use, the use of the LambdaMetafactory mechanism, and code generation examples were considered. Microbenchmarks of various approaches were presented, the code is on GitHub .
The report mentioned the features of two web frameworks - Micronaut and Quarkus . Quarkus is a very young Red Hat framework. Inspired by his mention, the next day added an example of its use in a set to the rest , written for a recent article .
At the end of the report, results were assessed with an assessment of various approaches in terms of criteria such as sustainability, speed, the possibility of using AOT , and the complexity of implementation.
Traditionally, for such meetings there was the opportunity to ask questions on the topic of the report, to communicate with colleagues in a relaxed atmosphere, reinforcing their strength in the break with buns with tea and coffee.
Presentation of the report: on Speaker Deck , the video will appear soon (see links below).
