“object” to “owner”

object

(1) (n.) A principal building block of object-oriented programs. Each object is a programming unit consisting of data (instance variables) and a range of operations (instance methods). A widget is an object. See also class.

(2) (n.) A graphics entity. A single image or model defined in 2-D or 3-D space.

object file

(n.) A file containing machine-language code. An executable file.

object-oriented design

(n.) A software design method that models the characteristics of abstract or real objects using classes and objects.

OBP

(n.) OpenBoot^TM programmable read-only memory (PROM).

octal

(adj.) Characteristic of the numbering system using 8 as its base, using the numerals 0–7 as its digits. In programs written in the Java^TM programming language, octal numbers must be preceded with 0.

OLIT

See OPEN LOOK Intrinsics Toolkit.

ONC+^TM services

(n.) The Sun^TM distributed services extracted from the Solaris^TM operating environment including RPC and NIS+.

On Item help

(n.) A form of help in which an application provides on-screen information about a particular command, operation, dialog box, or control.

online documentation

(n.) A disk-based form of documentation provided by many application programs, consisting of advice or instructions on using program features. You can access online documentation directly without the need to interrupt work or page through a manual.

opaque

(adj.) Characteristic of a particular piece of data if its value or format is not normally visible to functions that use it. For example, the input_token parameter to gss_init_sec_context() is opaque to the application, but significant to the GSS-API. Similarly, the input_message parameter to gss_wrap() is opaque to the GSS-API but important to the application that does the wrapping.

OpenBoot^TM

(n.) In SBus profiles, the facility by which the FCodes program can interrogate the host and determine the state of various parameters it addresses.

OPEN LOOK Intrinsics Toolkit

(OLIT) (n.) An X Window system-based widget set and library that is used to create applications which use the OPEN LOOK graphical user interface.

operating system

(OS) (n.) A collection of programs that monitor the use of the system and supervise the other programs that are executed by the collection.

option

(n.) A variation on or modification to a command, usually requested by use of a flag.

optional argument

(n.) An argument accepted but not required by a command.

ordinary file

(n.) In UNIX®, a file containing text data that is not executable. Contrast with executable file.

orthogonal

(adj.) Characteristic of a perpendicular or normal line.

OS

See operating system.

output

(n.) The information produced by a command, program, or such, and sent elsewhere; for example, to the terminal, to a file, or to a line printer.

output redirection

(n.) See redirection.

overlay

(1) (n.) A code fragment that is loaded into memory, replacing any previously loaded code fragment.

(2) (n.) A graphics image superimposed over a portion of another image; for example, when one window partially occludes another window.

overloading

(n.) The process of using one identifier to refer to multiple items in the same scope. In the Java^TM programming language, you can overload methods but not variables or operators.

overriding

(n.) The process of providing a different implementation of a method in a subclass of the class that originally defined the method.

overwrite

(v.) To write on an existing file, eliminating any previous text or graphics.

owner

(1) The person who created a file or directory.

(2) The attribute of a file or directory that specifies who has owner permissions.
