Three APIs are available — a Direct Persistence Layer which is " Plain Old Java Objects " ( POJO ); one which is based on the Java Collections Framework ( an object persistence approach ); and one based on the traditional Berkeley DB API.

Libraries ( APIs ) are categorized for different purposes.

Companies like Sun Microsystems, Novell, and Microsoft provide their own APIs so that many applications are written using their software libraries that usually have numerous APIs in them.

Configuration APIs provide programmatic control of administrative functions of the call centre platform which are typically accessed by a human administrator through a Graphical User Interface ( GUI ).

Both the database and most of its DBMS reside remotely, " in the cloud ," while its applications are both developed by programmers and later maintained and utilized by ( application's ) end-users through a web browser and Open APIs.

They are distinct from graphics APIs such as GDI and OpenGL that can be called by software to generate graphical output.

The APIs are similar ( storeBinary / readBinary ), but the encoding details are different, making these two formats incompatible.

Because X is an extensible system and designed for flexibility and so that there are ways new features can be offered without necessarily having to be built into X itself, these features are being supported with new APIs that run alongside X window system.

Typical modern parametric feature based modeler and freeform surface systems are built around a number of key C modules with their own APIs.

Exceptions to this are programs that contain direct calls to AIX kernel based APIs as there is no AIX kernel in PASE.

If necessary an AIX program may be built directly in PASE using a standard AIX XL C / C ++ compiler, for example if native APIs are to be used.

In that case APIs are provided to translate between the AIX style pointers and the native 16 byte pointers.

Closed source APIs can also have undocumented functions that are not generally known.

Nonetheless many of these specialised processor complex instruction sets do not have a publicly available native instruction set and native assembly language for proprietary hardware related reasons and are usually only accessible to software developers through standardized higher level languages and APIs.

These applications are able to detect software-based keyloggers based on patterns in executable code, heuristics and keylogger behaviours ( such as the use of hooks and certain APIs ).

Whereas graphics programmers had earlier relied on hand-coded assembly to make their programs run fast, most modern programs are written to interface with one of the existing graphics APIs, which drives a dedicated GPU.

The Internet Explorer web browser also exposes many APIs that are often used by applications, and as such could be considered a part of the Windows API.

The Wine project has working implementations of the Direct3D 8, 9 and 10 APIs ( they are, as of 23 July 2012, 100 %, 78 % and 79 % complete respectively ).

Code generation libraries are high-level APIs that can generate or transform byte code for Java.

There are also File Manager APIs such as that allow access to the raw resource fork ; however, they should be used only for applications such as copying a file – Apple strongly warns against using the resource fork as a “ second data fork .”

While some coders specialize in developing system-level functionality ( such as providing wrappers and APIs for other coders to base their code on ), others code effects which are usually visual representations of mathematical formulas, such as fractals or metaballs.

OTC drugs are usually regulated by active pharmaceutical ingredients ( APIs ), not final products.

As a result the Parlay / OSA APIs are specified in UML.

RubyCocoa is able to detect APIs that use format strings, like NSLog or NSString. stringWithFormat, and appropriately convert the variable arguments to the types specified in the format string.

It makes use of several network protocols like Internet Protocol ( IPv4 ), User Datagram Protocol ( UDP ), Dynamic Host Configuration Protocol ( DHCP ) and Trivial File Transfer Protocol ( TFTP ) and of concepts like Globally Unique Identifier ( GUID ), Universally Unique Identifier ( UUID ) and Universal Network Device Interface and extends the firmware of the PXE client ( the computer to be bootstrapped via PXE ) with a set of predefined Application Programming Interfaces ( APIs ).

It has access to the APIs of the PXE firmware extension ( Pre-boot, UDP, TFTP, Universal Network Device Interface ( UNDI )).

To display GUI elements, the SWT implementation accesses the native GUI libraries of the operating system using JNI ( Java Native Interface ) in a manner that is similar to those programs written using operating system-specific APIs.

* Transport Driver Interface, used by NT series Windows to abstract level 7 APIs into a common protocol for the Transport Protocol layer

In computing, the Oracle Call Interface ( OCI ) consists of a set of C-language software APIs which provide an interface to the Oracle database.

The look and feel of the widgets can be hard-coded in the toolkit, but some widget toolkit APIs decouple the look and feel from the definition of the widgets, allowing the widgets to be themed.

This execution environment is based on the use of a Java virtual machine and the definition of generic APIs that provide access to the interactive digital TV terminal's typical resources and facilities.

Prior to the adoption of anti-aliased drawing by X11, the use of 3D rendering APIs for 2D desktop rendering was undesirable because such APIs did not make the pixel accurate rendering guarantees that are part of the original X11 protocol definition.

In 2005 Cook, Rai, and Rosenberger proposed to drop all standardization efforts to introduce additional object-oriented query APIs but rather use the OO programming language itself, i. e., Java and. NET, to express queries.

The Java programming language XML APIs from Sun Microsystems consist of the following separate programming APIs:

* APIs for linking it on an external program such as a database, or using in a programming language to use the computer algebra system

The APIs and programming language for NeXTSTEP were so different from Windows and Macintosh system software that porting was very difficult.

Unlike relational databases, which had SQL as the standard query language, and widespread APIs such as ODBC, JDBC and OLEDB, there was no such unification in the OLAP world for a long time.

In addition to the programming language APIs available with ImageMagick, GraphicsMagick also includes a Tcl API, called TclMagick.

* New I / O ( usually " NIO "), a collection of Java programming language APIs introduced with the J2SE 1. 4 release of Java by Sun Microsystems

New I / O, usually called NIO, is a collection of Java programming language APIs that offer features for intensive I / O operations.

At that time, the primary goals were to remove " historical warts " from the language ; " easy things should stay easy, hard things should get easier, and impossible things should get hard ;" a general cleanup of the internal design and APIs.

This can sometimes cause problems when combining modules written in multiple languages, or when calling operating system or library APIs from a language other than the one in which they are written ; in these cases, special care must be taken to coordinate the calling conventions used by caller and callee.

It allows external document generators like phpDocumentor to generate documentation of APIs and helps some IDEs such as Zend Studio, NetBeans, JetBrains PhpStorm, ActiveState Komodo Edit and IDE, PHPEdit and Aptana Studio to interpret variable types and other ambiguities in the loosely typed language and to provide improved code completion, type hinting and debugging.
