Core dumps can save the context (state) of a process at a given state for returning to it later. Systems can be made highly available by transferring core between processors, sometimes via core dump files themselves. Core can also be dumped onto a remote host over a network (which is a security risk). [10]
A preprocessor performs macro definition, source code file inclusion, and conditional compilation. There is a basic form of modularity: files can be compiled separately and linked together, with control over which functions and data objects are visible to other files via static and extern attributes.
XMPFiles for embedding serialized metadata in files, and for retrieving embedded metadata. Adobe provides the XMP Toolkit free of charge under a BSD license. [4] [2] The Toolkit includes specification and usage documents (PDFs), API documentation (doxygen/javadoc), C++ source code (XMPCore and XMPFiles) and Java source code (currently only ...
Although reserved as a keyword in Java, const is not used and has no function. [2] [26] For defining constants in Java, see the final keyword. goto Although reserved as a keyword in Java, goto is not used and has no function. [2] [26] strictfp (added in J2SE 1.2) [4] Although reserved as a keyword in Java, strictfp is obsolete, and no longer ...
Java Pathfinder (JPF) is a system to verify executable Java bytecode programs. JPF was developed at the NASA Ames Research Center and open sourced in 2005. The acronym JPF is not to be confused with the unrelated Java Plugin Framework project. The core of JPF is a Java Virtual Machine.
In building applications, an API simplifies programming by abstracting the underlying implementation and only exposing objects or actions the developer needs. While a graphical interface for an email client might provide a user with a button that performs all the steps for fetching and highlighting new emails, an API for file input/output might give the developer a function that copies a file ...
Machine code is generally different from bytecode (also known as p-code), which is either executed by an interpreter or itself compiled into machine code for faster (direct) execution. An exception is when a processor is designed to use a particular bytecode directly as its machine code, such as is the case with Java processors .
The earliest published JIT compiler is generally attributed to work on LISP by John McCarthy in 1960. [4] In his seminal paper Recursive functions of symbolic expressions and their computation by machine, Part I, he mentions functions that are translated during runtime, thereby sparing the need to save the compiler output to punch cards [5] (although this would be more accurately known as a ...
