Eclipse Java Development Tooling or JDT has its own Java compiler at its core, aptly called the JDT Core consisting of the Java compiler and various tools including java model, search infrastructure, content assist, Abstract Syntax Tree Tools etc. Java 9 is the latest entry in the Java world bringing along-with it a "module" of changes - so to speak. Any change in the language standards affects JDT directly. While some of the earlier language specification changes affected only the compiler, Java 9, in contrast, has a direct impact on user who uses Eclipse IDE for creating and managing Java Projects. Java 9 introduces the concept of "Modules" which affects JDT from the compiler level to the project dependency layer affecting a normal user. Support for this feature will be dealt with, in detail, in this talk.
This talk would start with a brief overview of the Java 9 features especially the "module" feature that have direct impact on Eclipse users, describe the JDT support for features, touch upon some of the design aspects, and would conclude with a demo of Eclipse JDT for Java 9.
This talk cum tutorial aims at introducing Eclipse Kura, OSGi based framework for IOT gateway design.It starts with kura architecture and elements like bundles, services, web admin interface etc and a tour of available services for hardware interfacing, local wired,wireless connectivity and cloud connectivity options.It then proceeds with case study of building custom services with examples on HTTP REST Service, CoAP Service and InfluxDb service,with the help of these few bridging scenarios can be covered with cloud options like ThingSpeak,OpenSensors.io etc and focusing on storing data from gateway side using InfluxDb as an example.
Searching in big databases is the need of the hour. With ever growing applications and customer base, quicker search over the data helps you survive. Modeling Frameworks sit at the core of modern software. The increasing complexity of business requirements are reflected in the increasing complexity of the modeling framework. What if you could query the complex models within seconds? This is just one use case of VIATRA Query.
VIATRA Query is an Eclipse project. Initially conceived by the Budapest University of Technology and Economics, VIATRA is an Event-driven and Reactive Model Transformation Platform. We have used VIATRA Query to create a small search engine for Ecore models of EMF using Natural Language Based Rule Engine and would like to share our experience with it.
VIATRA Query enables the user to query the EMF models without having to manually traverse them. Complex queries can be converted into patterns. Parameters to models can be passed at runtime, something which is crucial to any query engine. The idea of creating a search engine using VIATRA Query opens up new and innovative ideas of working with Eclipse Modeling Framework.
