In software engineering, the initialization-on-demand holder ( design pattern) idiom is a lazy-loaded singleton. In all versions of Java, the idiom enables a safe, highly concurrent lazy initialization of static fields with good performance. [1] [2] The implementation of the idiom relies on the initialization phase of execution within the Java ...
The idiom can be seen as an action on a programming concept underlying a pattern in code, which is represented in implementation by contiguous or scattered code fragments. These fragments are available in several programming languages, frameworks or even libraries. Generally speaking, a programming idiom's semantic role is a natural language ...
Doxygen – Tool for writing software reference documentation. The documentation is written within code; Mkd – Extracts software documentation from source code files, pseudocode, or comments; Natural Docs – Claims to use a more natural language as input from the comments, hence its name
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere (), [16] meaning that compiled Java code can run on all platforms that support Java without the need to recompile. [17]
Applications. v. t. e. In programming language theory, semantics is the rigorous mathematical study of the meaning of programming languages. [ 1] Semantics assigns computational meaning to valid strings in a programming language syntax. It is closely related to, and often crosses over with, the semantics of mathematical proofs .
Object-oriented programming ( OOP) is a programming paradigm based on the concept of objects, [ 1] which can contain data and code: data in the form of fields (often known as attributes or properties ), and code in the form of procedures (often known as methods ).
[6] [7] [8] Perens did not base his writing on the "four freedoms" from the Free Software Foundation (FSF), which were only widely available later. [9] Under Perens' definition, open source is a broad software license that makes source code available to the general public with relaxed or non-existent restrictions on the use and modification of ...
Software design pattern. In software engineering, a design pattern describes a relatively small, well-defined aspect (i.e. functionality) of a computer program in terms of how to write the code . Using a pattern is intended to leverage an existing concept rather than re-inventing it. This can decrease the time to develop software and increase ...
