Jpype Documentation Release 0.7.0
JPype Documentation Release 0.7.0 Steve Menard, Luis Nell and others Jul 22, 2019 Contents 1 Parts of the documentation 3 1.1 Installation................................................3 1.2 User Guide................................................6 1.3 QuickStart Guide............................................. 17 1.4 API Reference.............................................. 27 1.5 JImport.................................................. 34 1.6 Changelog................................................ 36 1.7 Developer Guide............................................. 40 2 Indices and tables 53 Python Module Index 55 Index 57 i ii JPype Documentation, Release 0.7.0 JPype is a Python module to provide full access to Java from within Python. It allows Python to make use of Java only libraries, exploring and visualization of Java structures, development and testing of Java libraries, scientific computing, and much more. By gaining the best of both worlds using Python for rapid prototyping and Java for strong typed production code, JPype provides a powerful environment for engineering and code development. This is achieved not through re-implementing Python, as Jython/JPython has done, but rather through interfacing at the native level in both virtual machines. This shared memory based approach achieves decent computing preformance, while providing the access to the entirety of CPython and Java libraries. Contents 1 JPype Documentation, Release 0.7.0 2 Contents CHAPTER 1 Parts of the documentation 1.1 Installation JPype is available either as a pre-compiled binary for Anaconda, or may be build from source though several methods. 1.1.1 Binary Install JPype can be installed as pre-compiled binary if you are using the Anaconda Python stack. Binaries are available for Linux, OSX, ad windows are available on conda-forge. -

Noname manuscript No. (will be inserted by the editor) To the Attention of Mobile Software Developers: Guess What, Test your App! Luis Cruz · Rui Abreu · David Lo the date of receipt and acceptance should be inserted later Abstract Software testing is an important phase in the software development life- cycle because it helps in identifying bugs in a software system before it is shipped into the hand of its end users. There are numerous studies on how developers test general-purpose software applications. The idiosyncrasies of mobile software applications, however, set mobile apps apart from general-purpose systems (e.g., desktop, stand-alone applications, web services). This paper investigates working habits and challenges of mobile software developers with respect to testing. A key finding of our exhaustive study, using 1000 Android apps, demonstrates that mo- bile apps are still tested in a very ad hoc way, if tested at all. However, we show that, as in other types of software, testing increases the quality of apps (demon- strated in user ratings and number of code issues). Furthermore, we find evidence that tests are essential when it comes to engaging the community to contribute to mobile open source software. We discuss reasons and potential directions to address our findings. Yet another relevant finding of our study is that Continuous Integration and Continuous Deployment (CI/CD) pipelines are rare in the mobile apps world (only 26% of the apps are developed in projects employing CI/CD) { we argue that one of the main reasons is due to the lack of exhaustive and automatic testing. -

How Java Works JIT, Just in Time Compiler Loading .Class Files The
How Java works JIT, Just In Time Compiler ● The java compiler takes a .java file and generates a .class file ● JVM ultimately translates bytecode into native code, each time ➤ The .class file contains Java bytecodes, the assembler the same bytecodes are processed, the translation into native language for Java programs code must be made ➤ Bytecodes are executed in a JVM (java virtual machine), ➤ If we can cache translated code we can avoid re-translating the valid bytecodes are specified by Sun the same bytecode sequence • What if third parties create platform/OS specific codes? ➤ Why not just translate the entire .java program into native code? ● The JVM interprets the bytecodes ➤ JVM is platform/OS specific, must ultimately run the code ● Still need the JVM, the JIT works in conjunction with the JVM, not in place of it ➤ Different JVMs will have different performance, JITs are part of the overall JDK/Java performance ● How are classes loaded into the JVM? Can this be thwarted? Duke CPS 108 14.1 Duke CPS 108 14.2 Loading .class files The ClassLoader ● The bytecode verifier “proves theorems” about the bytecodes ● The “Primordial” loader is built-in to the JVM being loaded into the JVM ➤ Sometimes called the “default” loader, but it’s not ➤ These bytecodes may come from a non-Java source, e.g., extensible or customizable the way other loaders are compile Ada into bytecodes (why?) ➤ Loads classes from the platform on which the JVM runs ● This verification is a static analysis of properties such as: (what are loader and JVM written in?) ➤ -

API Compatibility Issues in Android: Causes and Effectiveness of Data
Noname manuscript No. (will be inserted by the editor) API Compatibility Issues in Android: Causes and Effectiveness of Data-driven Detection Techniques Simone Scalabrino · Gabriele Bavota · Mario Linares-Vásquez · Valentina Piantadosi · Michele Lanza · Rocco Oliveto the date of receipt and acceptance should be inserted later Abstract Android fragmentation is a well-known issue referring to the adop- tion of different versions in the multitude of devices supporting such an operat- ing system. Each Android version features a set of APIs provided to developers. These APIs are subject to changes and may cause compatibility issues. To sup- port app developers, approaches have been proposed to automatically identify API compatibility issues. CiD, the state-of-the-art approach, is a data-driven solution learning how to detect those issues by analyzing the change history of Android APIs (“API side” learning). In this paper (extension of our MSR 2019 paper), we present an alternative data-driven approach, named ACRyL. ACRyL learns from changes implemented in apps in response to API changes (“client side” learning). When comparing these two solutions on 668 apps, for a total of 11,863 snapshots, we found that there is no clear winner, since the two techniques are highly complementary, and none of them provides a Scalabrino and Oliveto gratefully acknowledge the financial support of the Italian Ministry of Education and Research for the PON-ARS01 00860 project on “Ambient-intelligent Tele-monitoring and Telemetry for Incepting and Catering over hUman Sustainability - ATTICUS”.
