AspectJ is an aspect-oriented programming (AOP) extension created at PARC (company), PARC for the Java (programming language), Java programming language. It is available in Eclipse Foundation open-source projects, both stand-alone and integrated into Eclipse (computing), Eclipse. AspectJ has become a widely used de facto standard for AOP by emphasizing simplicity and usability for end users. It uses Java-like syntax, and included IDE integrations for displaying Cross-cutting concern, crosscutting structure since its initial public release in 2001. Simple language description All valid Java programs are also valid AspectJ programs, but AspectJ lets programmers define special constructs called ''Aspect-oriented software development#Aspects, aspects''. Aspects can contain several entities unavailable to standard classes. These are: ;Extension methods: Allow a programmer to add methods, fields, or interfaces to existing classes from within the aspect. This example adds an acceptVisito ...

Cross-cutting Concern
In aspect-oriented software development, cross-cutting concerns are aspects of a program that affect several modules, without the possibility of being encapsulated in any of them. These concerns often cannot be cleanly decomposed from the rest of the system in both the design and implementation, and can result in either ''scattering'' (code duplication), ''tangling'' (significant dependencies between systems), or both. For instance, if writing an application software, application for handling Electronic health record, medical records, the indexing of such records is a core concern, while Data logging, logging a history of changes to the record database or user database, or an authentication system, would be cross-cutting concerns since they interact with more parts of the program. Background Cross-cutting concerns are parts of a program that rely on or must affect many other parts of the system. They form the basis for the development of aspect (computer science), aspects. Such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pointcut
In aspect-oriented programming, a pointcut is a set of join points. Pointcut specifies where exactly to apply advice, which allows separation of concerns and helps in modularizing business logic. Pointcuts are often specified using class names or method names, in some cases using regular expressions that match class or method name. Different frameworks support different Pointcut expressions; AspectJ syntax is considered as de facto standard. Frameworks are available for various programming languages like Java, Perl, Ruby, and many more which support pointcut. Background Due to limitations in various programming languages, cross-cutting concern has not modularized. Cross-cutting concern refers to parts of software that logically belong to one module and affect the whole system: this could be security or logging, for example. Aspect-oriented programming tries to solve these cross cutting concerns by allowing programmers to write modules called aspects, which contain pieces of code ex ...

JBuilder
JBuilder is a discontinued integrated development environment (IDE) for the programming language Java from Embarcadero Technologies. Originally developed by Borland, JBuilder was spun off with CodeGear which was eventually purchased by Embarcadero Technologies in 2008. Oracle had based the first versions of JDeveloper on code from JBuilder licensed from Borland, but it has since been rewritten from scratch. Versions JBuilder 1 through 3 are based on the Delphi IDE. JBuilder 3.5 through 2006 are based on PrimeTime, an all-Java IDE framework. JBuilder 2007 "Peloton" is the first JBuilder release based on the eclipse IDE framework. See also *Comparison of integrated development environments The following tables list notable software packages that are nominal IDEs; standalone tools such as source code editors and GUI builders are not included. These IDEs are listed in alphabetical order of the supported language. ActionScript ... References External linksHistory of s ...

NetBeans
NetBeans is an integrated development environment (IDE) for Java (programming language), Java. NetBeans allows applications to be developed from a set of modular software components called ''modules''. NetBeans runs on Microsoft Windows, Windows, macOS, Linux and Solaris (operating system), Solaris. In addition to Java development, it has extensions for other languages like PHP, C (programming language), C, C++, HTML5, and JavaScript. Applications based on NetBeans, including the NetBeans IDE, can be extended by third party developers.

Emacs
Emacs , originally named EMACS (an acronym for "Editor MACroS"), is a family of text editors that are characterized by their extensibility. The manual for the most widely used variant, GNU Emacs, describes it as "the extensible, customizable, self-documenting, real-time display editor". Development of the first Emacs began in the mid-1970s, and work on its direct descendant, GNU Emacs, continues actively; the latest version is 28.2, released in September 2022. Emacs has over 10,000 built-in commands and its user interface allows the user to combine these commands into macros to automate work. Implementations of Emacs typically feature a dialect of the Lisp programming language, allowing users and developers to write new commands and applications for the editor. Extensions have been written to, among other things, manage files, remote access, e-mail, outlines, multimedia, git integration, and RSS feeds, as well as implementations of ''ELIZA'', ''Pong'', '' Conway's Life'', ...

Apache Ant
Apache Ant is a software tool for automating software build processes which originated from the Apache Tomcat project in early 2000 as a replacement for the Make build tool of Unix. It is similar to Make, but is implemented using the Java language and requires the Java platform. Unlike Make, which uses the Makefile format, Ant uses XML to describe the code build process and its dependencies. Released under an Apache License by the Apache Software Foundation, Ant is an open-source project. History Ant ("Another Neat Tool") was conceived by James Duncan Davidson while preparing Sun Microsystems's reference JSP and Servlet engine, later Apache Tomcat, for release as open-source. A proprietary version of Make was used to build it on the Solaris platform, but in the open-source world, there was no way of controlling which platform was used to build Tomcat; so Ant was created as a simple platform-independent tool to build Tomcat from directives in an XML "build file".

Java Annotation
In the Java computer programming language, an annotation is a form of syntactic metadata that can be added to Java source code. Classes, methods, variables, parameters and Java packages may be annotated. Like Javadoc tags, Java annotations can be read from source files. Unlike Javadoc tags, Java annotations can also be embedded in and read from Java class files generated by the Java compiler. This allows annotations to be retained by the Java virtual machine at run-time and read via reflection. It is possible to create meta-annotations out of the existing ones in Java. History The Java platform has various ''ad-hoc'' annotation mechanisms—for example, the ''transient'' modifier, or the ''@Deprecated'' javadoc tag. The Java Specification Request JSR-175 introduced the general-purpose annotation (also known as ''metadata'') facility to the Java Community Process in 2002; it gained approval in September 2004. Annotations became available in the language itself beginning w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Generics In Java
Generics are a facility of generic programming that were added to the Java programming language in 2004 within version J2SE 5.0. They were designed to extend Java's type system to allow "a type or method to operate on objects of various types while providing compile-time type safety". The aspect '' compile-time type safety'' was not fully achieved, since it was shown in 2016 that it is not guaranteed in all cases. The Java collections framework supports generics to specify the type of objects stored in a collection instance. In 1998, Gilad Bracha, Martin Odersky, David Stoutamire and Philip Wadler created Generic Java, an extension to the Java language to support generic types. Generic Java was incorporated in Java with the addition of wildcards. Hierarchy and classification According to ''Java Language Specification'': *A type variable is an unqualified identifier. Type variables are introduced by generic class declarations, generic interface declarations, generic method declar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java 5
The Java language has undergone several changes since JDK 1.0 as well as numerous additions of classes and packages to the standard library. Since J2SE 1.4, the evolution of the Java language has been governed by the Java Community Process (JCP), which uses ''Java Specification Requests'' (JSRs) to propose and specify additions and changes to the Java platform. The language is specified by the ''Java Language Specification'' (JLS); changes to the JLS are managed undeJSR 901 In September 2017, Mark Reinhold, chief Architect of the Java Platform, proposed to change the release train to "one feature release every six months" rather than the then-current two-year schedule. This proposal took effect for all following versions, and is still the current release schedule. In addition to the language changes, other changes have been made to the Java Class Library over the years, which has grown from a few hundred classes in JDK 1.0 to over three thousand in J2SE ...

BCEL
The Byte Code Engineering Library (BCEL) is a project sponsored by the Apache Foundation previously under their Jakarta charter to provide a simple API for decomposing, modifying, and recomposing binary Java classes (I.e. bytecode). The project was conceived and developed by Markus Dahm prior to officially being donated to the Apache Jakarta foundation on 27 October 2001. Uses BCEL provides a simple library that exposes the internal aggregate components of a given Java class through its API as object constructs (as opposed to the disassembly of the lower-level opcodes). These objects also expose operations for modifying the binary bytecode, as well as generating new bytecode (via injection of new code into the existing code, or through generation of new classes altogether.) The BCEL library has been used in several diverse applications, such as: *Java Bytecode Decompiling, Obfuscation, and Refactoring *Performance and Profiling :Instrumentation calls that capture performance metric ...
